American mahjong questions, answered.

• You hold thirteen tiles and draw and discard one at a time until fourteen match a printed line.
• Three things separate it from Asian variants: eight jokers, the Charleston, and an annual card.
• Groups are identical tiles only — pungs, kongs, quints, sextets. No chows.

• A Chinese hand is four melds and a pair scored by faan; an American hand is one exact card line.
• No chows here, and eight jokers that work only inside groups of three or more.
• Every hand opens with the Charleston, a structured pass with no Chinese equivalent.
• 152 tiles rather than 144, and scoring is read off the card, not counted.

• You may claim a discard only to complete a pung, kong, quint or sextet, or to declare Mah Jongg.
• Consecutive numbers printed on the card, like 222 333 444, are three separate pungs, not a run; each one is built the ordinary way.
• If you learned riichi or Hong Kong rules, this is the first habit to unlearn.

• Honors: 16 winds (four each North, East, West, South) and 12 dragons (four each red, green, soap).
• Flowers: eight tiles in four designs, each printed twice. Jokers: eight wild tiles.
• That is a 144-tile Chinese set plus the eight jokers. Blank spares some sets include are not part of the count.

• Jokers are the only wild tiles and the only group a Chinese set lacks.
• Flowers are not extra: Chinese sets also carry eight flower and season tiles, but there they are bonuses drawn and replaced.
• In American play flowers stay in your rack and count toward the hand.
• A 136-tile Japanese set drops flowers entirely, so it cannot play American.

• 38 × 4 = 152, so every tile is in the wall — nothing is set aside.

• Groups you call go face up on the top ledge of the rack, where the table can read them.
• After the Charleston you should still have thirteen: you passed three and received three.
• Recount after every pung and kong; a drifting count is the most common dead hand.

• The deal moves on: the player to the current dealer's right becomes the new East.
• A dead hand often plays for a wall game on purpose, since it can no longer win.

• Because play passes to the right, that is the player on the discarder's right.

• You must already hold two of the tile for a pung, and three for a kong; you cannot call cold.
• A quint or sextet needs jokers, since only four copies of any tile exist.
• Required singles cannot be called for at all, and a pair must be two natural tiles, so neither is a claim.
• The claimed tile goes on top of your rack, exposed.

• You may never blind-pass a joker.

• It cannot sit alone as a single, and it cannot be half of a pair.
• It cannot fill a required single either, such as one wind in NEWS or a digit in a year hand.
• Jokers are never printed on the card; group size tells you whether one is allowed.
• A joker substitutes by tile identity, not by suit.

Read: Joker Rules·The NMJL Card

Also asked as: what can a joker be used for · are jokers wild in mahjong · can a joker be a flower · joker rules american mahjong

• Two naturals plus a joker is a legal pung — the restriction is about the size of the group, not about mixing.
• The same ban covers singles: NEWS needs four real winds, and a year hand needs real digits.
• Keep jokers at the far right of your rack, physically apart from your pairs, so you cannot miscount one.

Also asked as: can a joker be part of a pair · joker as a single · why can't jokers make pairs · joker pair rule

• The order is pick, rack, exchange, discard. Swapping before your turn begins kills your hand.
• You may take more than one joker in a turn, and you may exchange into your own exposure.
• A kong is no exception: a joker in an exposed kong can be redeemed too, and the group stays four tiles.
• Jokers in a wrongly exposed group are not redeemable.

• Two forms, not three: concealed (all four drawn by you, kept in the rack) and exposed (you held three, jokers allowed, and called the fourth).
• There is no "added" kong. Once you expose a pung and discard, that group is fixed — a fourth tile drawn later cannot join it.
• No replacement tile and no dead wall. Expose the kong, discard one, play on: the called tile was your tile for that turn.
• A kong made entirely of jokers is legal, but only while it stays concealed — the tile you call for an exposure must be a natural tile.

Also asked as: what is a kong in mahjong · types of kong · concealed kong exposed kong added kong · do you draw a replacement tile for a kong · kong dead wall · kong replacement tile

• Every other tile comes off the wall; calling a pung or kong from a discard makes the hand dead immediately.
• A concealed kong built from your own tiles is fine, and a joker exchange on your turn does not break concealment.
• The winning tile is the exception — you may claim a discard to declare Mah Jongg on a C hand.
• C lines print higher because they are harder to complete.

• Wrong tile count: thirteen in play, fourteen only at the instant of your draw or your declaration.
• A Mah Jongg call that does not match a line, or exposures that fit no line at all.
• A joker in a pair or a single, or exposing any part of a hand marked C.
• A joker exchanged before you pick, or a claimed tile named wrongly.

Also asked as: why is my hand dead · dead hand mahjong rules · what kills a mahjong hand · common dead hand mistakes

• Once the call is made and stands, you stop picking and discarding for the rest of the hand, and you pay the winner the full value of their hand.
• Before that call you are still in the hand: say nothing, discard only tiles that have been seen, and steer toward a wall game.
• Exposures you made stay on the table — jokers in them can still be exchanged, but not a joker in the exposure that killed the hand.
• Call someone dead and be wrong, and the hand plays on: at the end, whoever was wrong pays the other 50 cents or 50 points.

• Won off a discard: the thrower pays double, the other two pay single.
• Self-drawn: all three opponents pay double.
• A 25-point line therefore collects 100 on a discard and 150 on a self-draw.
• Zero jokers in the winning hand doubles the printed value, Singles & Pairs excepted — the card prints it, though a few tables treat it as optional.

Also asked as: how does scoring work in american mahjong · mahjong points explained · who pays who in mahjong · mahjong scoring for beginners

• A hand collects four times its printed value on a discard but six times on a self-draw — 50% more.
• That gap is why a strong player sometimes lets a claim pass and waits for the draw.
• It also means the player who feeds the hand carries the largest single share of the payment.

Read: Scoring & Payment

Also asked as: self draw vs discard mahjong · why is self picked worth more · mahjong payment rules · does everyone pay on mahjong

• The wall is four equal stacks, and every hand assumes four racks and four payments.
• A common workaround is "ghost": deal a fourth hand and auto-play its turns so the Charleston and the wall still work. It is a house variant, not NMJL.
• If you are short a player, find a fourth rather than improvising.

• The National Mah Jongg League publishes it every spring; the 152-tile set never changes, only the legal hands.
• A win is 14 tiles matching one printed line, including its suit rules and its X or C marker.

• 222 is a pung, 4444 a kong, 55555 a quint; a lone 8 is a single tile, not a group.
• Spaces separate groups; digits written together are one identical group.
• The suit comes from the line's colors, never the number — the card never prints "three of dots."

• NEWS means one of each wind — all four, never three, never a joker.
• Flowers are ordinary tiles, all eight interchangeable, never wild.
• Dragons lock to suits (Red = craks, Green = bams, White = dots) unless white is a zero, when it is suitless.

• Exposed is permission, not obligation — you can build an X line quietly and still win.
• Once you expose, the hand is locked to that line and the table can read your direction.
• The friendliest lines on any card are the pung-based X lines with no joker requirement.

• You may claim the 14th tile if it completes Mah Jongg; that is the single allowed exception.

• Group sizes, suit relationships, flower counts and the X or C marker all belong to the line.

• Two colors mean exactly two suits, never "this one must be bams."

• Dragons are the exception: they belong to a suit by identity, not by print color.

Read: The NMJL Card·Card Traps

Also asked as: do card colors mean suits · red green blue mahjong card · which suit do i use · same color same suit · can any color be any suit

• "(Any 2 Suits)" means two suits, assigned by you; it never names them.
• In a like-numbers line, "any" refers to the number: pick 3s or 7s, and every numbered group uses it.
• It does not loosen identity: a 5 in dots and a 5 in bams never make one pung.

Also asked as: what does any 2 suits mean · any 3 suits on the card · any like numbers meaning · what does any mean in parentheses · flexible suits mahjong

• The card never prints "joker"; the group size is what tells you one is allowed.
• A group in your own rack may be all jokers; an exposure cannot, because the tile you call has to be a natural tile.
• Scatter jokers through your rack and you will eventually treat one as half a pair; keep them at the far right.

Also asked as: can a joker be a pair · joker in a single · where can jokers go · joker rules on the card · how many jokers in a quint

• Quint and sextet lines are hostage to whether you actually hold the jokers.
• Dealt four of a kind when the line wants five? Hold all four; one joker is easier to find than a fifth natural.
• Singles & Pairs forbids jokers entirely, which is why it pays what it does.

Also asked as: how many jokers does a quint need · does this hand need a joker · sextet jokers · which hands require jokers · joker dependent hands

• A pung where the line asks a kong is the commonest.

• No credit for being "mostly" one line, or for the best parts of two.
• Cross-line hands usually break a suit rule too, so the error compounds.
• If you cannot point to the row you are building, it is not a legal hand.

• You do not compute anything: find the line, read the number.
• Higher values track difficulty, not luck — concealed, joker-dependent and singles-heavy lines pay more.
• Multipliers for self-draw, discarder-pays-double and jokerless sit on top; the line's printed value never changes.

• Lines built on the year digits commonly ask for that digit block more than once.

Also asked as: why does the card repeat the year · same group twice on the card · two identical pungs · does it mean two groups · repeated blocks in a hand

• Locking one hand before your first discard is the classic beginner error: the Charleston hands you tiles that invalidate it.
• Experts pick a direction in about three seconds because they know the card's structure, not seventy rows.
• Score candidates on joker requirement, group rarity, and X versus C; the line easy on all three is your default.

• Treat your hand choice as a live distribution: 40/35/25 at round 3, 60/30 at round 6, 85/15 by round 9.
• A beginner locks a direction by round 3 and then sits on dead tiles for the rest of the hand.
• Sunk cost isn't cost. Dropping a direction you already put four tiles into is correct when the math moves.

• A workable fold test: more than two or three tiles away once the wall is in its last third.
• Four-plus effective tiles out with fewer than 20 tiles left is a dead hand walking.
• Distance matters less than kind: a missing pair you cannot call is worse than a pung you can draw.

Also asked as: how many tiles away is too far mahjong · when is a hand too far behind · is my hand still winnable · how far off can you be in mahjong · wall running out hand not close

• You are more than two or three tiles away and the wall is in its final third.
• The tiles you need for a pair have already been discarded, because pairs cannot be called or joker-filled.
• An opponent has two or more exposures while you have shown none, or you keep drawing blanks while others progress.

Also asked as: when to fold in mahjong · should I abandon my hand · how do I know my hand is dead · when to stop building american mahjong · give up on a hand

• Safe: a tile already discarded two or three times, a suit no opponent is collecting, and any discarded joker, which can never be called.
• Dangerous: a tile nobody has thrown, the neighbor of a just-called group, and a flower late in the hand.
• No new calls. A pung from a folding hand spends a turn and advertises a line you are not going to finish.

Read: Defensive Play

Also asked as: what is folding in mahjong · how do you play defense american mahjong · safe discard when you can't win · what to throw when you give up · playing safe tiles

• Fastest means few of your needed tiles are gone, one line is clear, and nobody is exposed and close.
• Pushing is also cheap when your discard is safe anyway — if the throw can't deal in, attacking costs little.
• Re-run it every turn: draw, discard, observe, infer who is ahead, then choose. Most players skip the infer step.

Also asked as: offense vs defense mahjong · when to attack when to defend · should I keep pushing my hand · aggressive or safe mahjong strategy · balance attack defense

• At one tile out, stop optimizing. Don't switch lines; throw your safest tile, not your most useless one.
• A broken hand costs you a redeal. Dealing the winning tile costs you double. That asymmetry is the defensive game.
• A self-draw is paid double by all three; a discard only by the discarder, so holding one turn can be worth it.

Also asked as: when to stop pushing mahjong · should I keep going for mah jongg · one tile away what do I discard · is it worth folding when I'm close · stop chasing the win

• A pung of 4-dots plus a kong of 8-dots means dots, and every dot you throw is live danger.
• It also tells you what they are *not* doing, which is often more useful than what they are.
• One exposure gives direction, two confirm the target — and an early exposure usually means a fast player, ahead of you.

Read: Defensive Play·Reading the Table

Also asked as: what does an exposed pung mean · how to read exposures mahjong · what does a kong tell you · reading opponent melds · what can I tell from a pung

• An exposed hand cannot pivot, so you can read the rest of it off the card.
• A joker in an exposure is a loan, not a possession. Anyone with the natural tile can trade for it.
• Strong players expose false directions on purpose, so treat one exposure as a hypothesis, not a fact.

Also asked as: what do exposures hide mahjong · can I trust an exposure · why do good players expose a hand they aren't playing · false direction mahjong · reading exposed melds

• The dangerous tiles are the ones nobody has thrown yet, especially in a suit that has gone quiet.
• Add the pattern dangers: neighbors of a just-called group, flowers late, anything matching an exposed suit.
• Stage the risk by the wall: early is over 60 tiles left, mid is 30 to 60, late is under 30.

Also asked as: how to know which tiles are dangerous · safe tile tracking mahjong · counting discards american mahjong · what tiles should I avoid throwing · danger tile list

• What opponents pass in the Charleston previews what they will throw: craks pushed across the table make craks safer for you.
• One pass is noise. Three passes across a Charleston start to show a pattern.
• Late in the hand, a live tile in a silent suit is the most dangerous discard on the table.

Also asked as: what do discards tell you mahjong · reading discard piles · what suit is my opponent collecting · suit that never gets discarded · discard patterns meaning

• A discarded joker usually means one of three things: one tile from Mah Jongg and hunting a pair, a Jokerless hand, or pure defense.
• All three make the table more dangerous. Tighten your next few discards and stop feeding that lane.
• Off-suit tiles from someone with two exposures are usually a dying line, not a safe one.

Also asked as: why did they throw a joker · opponent changed suits late · what does it mean when someone discards a joker · desperate hand mahjong · reading a pivot

• If your line needs more jokers than that number, the line is finished. Pivot now, not four turns from now.
• One or two is the working range. Three or four means commit to a line that genuinely needs them. Five-plus is usually a trap.
• A concealed joker cannot be taken from you; an exposed one can. That is the whole timing problem.

Also asked as: how many jokers should I hold · joker counting mahjong · eight jokers strategy · how to budget jokers · joker math american mahjong

• One joker finishing a pung you will never draw beats two sitting in reserve.
• Joker value spikes after mid-hand: it may be your only fast route to the last tile, or your only way to change lines.
• Don't park a joker in an unfinished exposure — a half-built group stays visible, and stealable, longer.

Also asked as: when to use a joker in mahjong · should I save my jokers · best time to play a joker · joker timing · spend or hold joker

• A hand with no joker anywhere pays double, and doubles stack — Jokerless on a self-draw is four times base.
• Quints need at least one joker and sextets at least two, because only four copies of any tile exist. Flowers are the exception.
• Decide before mid-hand. Passing on an exchange commits you; after that, every joker in your rack is dead weight.

• Win rate climbs to about 55.7% at five jokers, then falls to 52.0% at six and 46.6% at seven in aggregate play data.
• Jokers can't fill a pair and can't be passed in the Charleston, so surplus jokers are frozen rack slots.
• Too many options can cost you the thread of the hand — that is the paradox-of-choice cost showing up in the numbers.

Also asked as: can you have too many jokers · is 5 jokers bad · joker hoarding mahjong · more jokers better · joker win rate

• Keep pairs and near-pungs. They are the skeleton of almost every line, and a pair is the one thing a joker cannot finish.
• Pass the lone 2-crak when nothing else in your rack is a crak.
• Never pass a joker. It is illegal, and passing one kills the hand outright.

Also asked as: what should I pass in the charleston · which tiles to pass mahjong · charleston passing strategy · what not to pass · first pass decision

• A tile you needed landing in your pass tray tells you that player doesn't want that suit or number.
• Wind-dumping is a loud tell: a player passing winds is unlikely to be on a Winds and Dragons hand.
• One pass is noise; three passes across a Charleston start to show a pattern. And players bluff, so treat early passes as hints.

• Want 2468 bams and holding a spare 1-crak? Pass a 3-bam and let them read "consecutive" instead.
• Once your shape is set, the last fixed pass can carry a decoy to the player across from you.
• The return pass is legal: send back a tile you received earlier. It cleans your rack and clouds their read.

• Tiles in your rack are not a commitment. A pung on the table is.
• Even a concealed line can fall back to an exposed line, but only if you have not exposed or called anything yet.
• Say the whole line to yourself before your hand goes down. Decide the line, then expose — never the other way round.

• Count your needed tiles in the discards before you commit. If they are all visible, the hand is over regardless of how it feels.
• Count jokers by subtraction, never by memory: eight minus yours, minus exposed, minus discarded.
• Track the wall's third. The same discard is reasonable at 70 tiles left and reckless at 25.

• Platform data has 89.3% of games ending in a win and 10.7% in a wall game, so an equal share of the wins is 22.3%.
• Below 20% over a long run points to a systematic flaw, not bad luck.

• A world champion put it at about 50% luck right after winning the title — not as modesty, as method.
• Grade decisions you can replay: the Charleston pass, the fold you made too late, the hand you wanted over the card's.
• Structure matters too: in one 2024 analysis, two kongs plus two pungs took 57.96% of wins; Singles and Pairs took least.

• Tilt, playing on after a bad beat, costs more points than any technical flaw.
• Stop when you're tired and take breaks; judgment decays over a long session, and the last hour is where hands get donated.
• Replay your worst decision of the night, then fix one recurring mistake that week. "Play better" fixes nothing.

• Don't announce it yourself. Saying it out loud hands the other three extra picks, which is exactly what they want.
• While you are still playing, throw only tiles that have already been seen and never pung or kong — a call only hands out information.
• Once it is called, your discards stop deciding anything; you keep your seat and pay the winner the full value of their hand.
• Payment is the same either way, so the defensive stretch is not wasted — it is the only part you can still influence.

Also asked as: what do I do with a dead hand · my hand is dead now what · can I still play with a dead hand · dead hand strategy · should I announce a dead hand

• A joker only pays when it replaces a tile you cannot otherwise get; three left in your rack at the end of a lost hand were wasted draws.
• Win rate peaks around five jokers and falls at six and seven, so "more is better" is measurably wrong.
• Keep the ones you have — never discard one — but spend them on your scarcest group instead of collecting them.

• Pairs matter because they cannot be called or joker-filled, so they are the hardest thing to rebuild. Early on, protect them.
• In full defense, breaking your own pair beats throwing a live tile into an exposed hand.
• The pair you cannot replace is the one whose tiles are all still unseen. The pair whose copies are already out is already dead.

• Call only if that tile serves the line you already chose and the group actually appears in it.

• Each player gets a rack, about 19 inches, with a sliding pusher at one end; four players need four.

• Look for "American" and either "152 tiles" or "166 pieces" in the listing.

• Thin tiles with printed faces lose contrast and are hard to read across the table.
• Cheap pushers stick, so the wall collapses and every deal slows down.
• Some inexpensive sets are 144-tile Chinese sets with joker stickers added, which breaks the card's count.
• The usual outcome is buying twice, and the second set costs more.

Also asked as: cheap mahjong set problems · why are mahjong sets so expensive · beginner mahjong set mistakes · are budget mahjong sets any good

• Premium and design-house sets run roughly $300–$500, buying tile weight, bigger faces and a hard case rather than a better game.
• Below about $100 you usually get tiles without racks, thin printed tiles, or a 144-tile set.
• Add the card: roughly $14 standard, $15 large print.
• Prices move with material and brand, so treat any figure as a band, not a quote.

• Melamine and denser composites feel heavier, shuffle deeper and hold engraved detail longer than thin acrylic.
• Upgraded racks are wood or acrylic with smooth pushers; cheap ones flex and jam mid-deal.
• A hard case protects the set in transit; a soft bag is fine if it stays home.
• At the top end you also pay for colour and design — a reason to spend, not a playing advantage.

• Red flags: "144 tiles", "Chinese mahjong", "Hong Kong style", no rack count, or "mini/travel" with no measurements.
• American tiles carry Arabic numerals beside the suits, so the faces read without Chinese characters.
• If the seller cannot tell you the joker count in a message, buy elsewhere.

• The NMJL releases a new card each April, and only that year's card defines the legal hands and values.
• It costs roughly $14 standard or $15 large print, and it is the most important purchase after the tiles.

• You need a flat, stable surface with room for four racks, the wall and four discard areas.
• A cloth or felt cover quiets the tiles and stops them sliding; some players use one, many do not.
• The standard kit is tiles, four racks with pushers, dice, a case and the card.
• On glass or a very hard table, a cover is worth it for noise and protection.

• Most people stop needing help after a handful of sessions at a real table — faster than studying alone, because someone corrects you before the mistake lands.

• One hand runs about 5–15 minutes; a full session usually runs two to three hours.
• The deal passes to the next player after every hand, so there's no natural finish line the way there is in a fixed-round game.
• Most groups pick a clock ("we stop at four") or a number of hands. Tournaments run timed sessions instead.

• With 152 tiles and a fixed card, a wall game — nobody wins, nobody pays — happens more often than beginners expect.
• Everyone works from the same menu of hands, so the edge comes from Charleston choices, when you expose, how you spend eight jokers, and what you refuse to discard late.
• Over one hand, variance dominates. Over twenty, it stops being the explanation.

• Reading the card: the hand builder walks a line tile by tile; the solver tells you which card section your tiles could fit.
• Tile recognition: solitaire and the memory game teach the faces faster than a rulebook does.
• None of it teaches the Charleston or table reading. Those need three other people, which is the point of the game.

• Groups meet on a video call with a shared digital board, or with physical tiles held up to the camera — both are common.
• Apps host pickup tables and private rooms, and enforce the card so nobody argues about a hand.
• The card, the Charleston and the joker restrictions are identical online, so nothing you learn there is wasted. Agree house rules in the chat first, and say your calls out loud.

• Nobody deals from a stack. The mess is the shuffle, and it's part of the pleasure of the game.
• Then each player builds a wall in front of themselves: 19 stacks, two tiles high, 38 tiles each.
• The four walls get pushed together into a closed square. Leave no gaps — a gap makes the break miscountable later.

• Everyone rolls once; the highest total takes East and deals the first hand.
• East rolls again, then counts that many stacks in from the right end of their own wall — that's the break, the equivalent of cutting a deck.
• Dealing starts from the break. East takes 14 tiles, everyone else 13. The dice never affect play after that.

• Lay the tiles in card order with the groups separated, and sandwich any joker between the naturals it stands for, so the table can read your line at a glance.
• Don't sweep the tiles up early. That's the fastest way to turn a win into an argument.
• If the winning tile came off someone's discard, call it before the next player draws — once they've drawn, that tile is dead and your chance is gone.

• It isn't a rule with a penalty attached; it's table etiquette, and it's what makes calling possible at all.
• American play has no silent claim and no "ron." If you don't name it, you slow the table and invite disputes.
• The other half of the habit: never comment on what someone else discarded. Name your own, stay quiet about theirs.

• Give a five-minute explanation, not a lecture: the goal, the turn, what a joker does, how calling works. Then deal.
• Play the first round open-handed so everyone can see a hand being built. Switch to hidden tiles for round two.
• Name one rule-reader with the cheat sheet in front of them, and settle house rules — second Charleston, stakes, wrong-call penalty — before the first deal, not mid-hand.

• Prop the card open at the one line you're playing instead of scanning all of it. Scanning is what eats the clock.
• Count to fourteen every turn. Most slowdowns are confusion, not thought.
• Ask short and fast — "whose turn?", "can I still call that?" A quick question keeps the rhythm; a long silent panic breaks it. And skip the apology tour.

• Mid-hand, ask short factual things — whose turn, whether a tile is still claimable, what a call meant. Those keep the game moving.
• Save "why did you do that?" and anything about strategy for after the hand. Nobody should be explaining their decisions while three people wait.
• Never ask what someone is building, and never coach another player mid-hand, even kindly.

• The barrier isn't arithmetic, it's reading the card and holding fourteen tiles on a rack built for adult hands.
• Shorten it: play open-handed, skip the Charleston for the first few games, or chase one simple line instead of the whole card.
• The 152 tiles and eight jokers are a lot to manage physically. A rack and a flat table matter more than the rules do.

• A cluster-randomized trial in Hong Kong nursing homes — 110 residents, twelve weeks, mahjong compared with tai chi and with simple crafts — found mahjong players held certain cognitive scores while the crafts group declined.
• That's maintenance in people who already had impairment, not a boost for a healthy adult.
• The likeliest active ingredient is the hour itself: seated, social, mildly demanding, and repeated weekly. That's a good habit, not a treatment.

• What the trials show is that structured activity can slow decline in some measured domains for people who already have cognitive impairment. Preventing a disease is a different claim.
• The impressive-sounding risk reductions come from observational studies, where people well enough to play weekly are healthier to begin with. That confound doesn't go away.
• Treat it as a pleasant, social habit. If you're worried about your memory or someone else's, that's a conversation with a doctor, not a table.

• Four seats, a fixed weekly time, and a game that pauses for conversation between hands — that's a standing appointment with three other people.
• It's why the game persists in libraries, JCCs, senior centers and church halls rather than in arcades.
• The failure mode is the opposite of loneliness: a table that becomes an obligation. Two hours, once a week, is the shape most people sustain.

• The NMJL sells a large-print card for about $15 against about $14 standard. Buy it. Reading the card is the whole game.
• Look for tiles around 30 mm and up with engraved, high-contrast faces — printed faces wear smooth and blur across a table.
• Lighter sets and smooth-gliding pushers matter more than tile weight. Nothing in the game requires fast hand movement, and the click of the tiles is a genuine aid.

• Every legal hand has a value printed on the card. Scoring is a lookup in points, not a bet.
• Many groups never put money on it at all. Where stakes exist they're usually nickels, dimes or quarters per point, and a session settles to a few dollars.
• Some tables use a "pie" — a capped buy-in so nobody can lose more than they brought. That's a house rule, agreed before the first deal. If a table's stakes make you uneasy, say so early or find another table.
