Mahjong Groups

The board is cut into real American sets. Clear a pung, a kong, a quint or a sextet by taking every tile in it. A tile only comes off when nothing covers it and one side is open, so which lane you open first decides what you can reach later.

The four sets on this board

An American set holds four of every tile and eight jokers. Anything bigger than four is therefore holding at least one joker, which is exactly how a quint or a sextet happens at a real table. Nothing here is bigger than six, and nothing is smaller than three.

Suits are worth craks 1, dots 2, bams 3, winds 4 and dragons 5. Finishing a set with a joker adds 10, and clearing two sets of the same suit back to back multiplies the second one by up to 4.

How to read the board

Playing it well

Why there are no pairs

Most tile-matching solitaires run on the Chinese 144-tile set, which has no jokers in it. With no wild tile available, the only move left is pairing two identical tiles, and the entire board gets built around that one idea.

The American set carries eight jokers, and a joker has a narrow job: it completes a group of three or more. It cannot be a single tile and it cannot make a pair. Once you take that rule seriously, pairs come off the table and the smallest legal set is a pung. Full detail is on joker rules.

What the board borrows, and what it changes

The useful parts of the tile-solitaire genre are all here, and most of them cost nothing: an open-sets counter that reads honestly, hints that never take points away, a no-clock mode for learning, and one board a day shared by everyone. The shuffle is deliberately expensive, twenty seconds once per board, so it stays a rescue instead of becoming a habit.

Two things are different. Deals are made by lifting whole waves backwards, so every wave stays open at the same moment and you get a real choice instead of one forced move. And when the remaining sets can no longer reach an empty board, the game says so out loud and re-lays for free rather than letting you clear tiles until nothing is left.
