Charleston Ledger

Nine tiles cross hands before a single discard is thrown, and most players have forgotten them by the time East lets go of the first tile. This drill makes those nine the opening entry of a running ledger, then asks what they actually prove. Some rounds are genuinely unreadable, and saying so is the right answer.

What does the Charleston plus what this seat has thrown tell you?

Members-only rounds

The eight-round set and the unreadable cases are part of the member plan. Those are the rounds that teach you when to stop guessing.

What this drill assumes, and what it never does

Every round is built so the right answer is forced by the tiles on screen. A seat that has exposed three of a kind has named its suit out loud; a seat that passed a suit away before the first discard and kept throwing it has told you the opposite. Nothing is left to a hunch, and no round asks you to recall a list.

Jokers never appear in a Charleston pass here. Passing one is not a clever move, it is a ruined hand, and a trainer that handed you a joker in a pass would be teaching the wrong habit.

This drill teaches generic table reasoning: suits, exposures, and the shape of what a seat keeps. It does not read the official NMJL card, it names no year's hands, and it stores nothing off your device. Your purchased card stays the authority on what any hand is worth.

About Charleston Ledger

Charleston Ledger turns the nine tiles you pass and receive into a written record, then helps you read what one seat must be collecting.

Keeping a ledger turns the Charleston from a blur of tiles into readable evidence. The free version covers four rounds; the member set adds the cases where the honest read is that nothing can be known yet.
