The book

Fifteen short chapters: the rules exactly, where the game came from, what thirty million games taught us, the one big idea and three adjustments, then a chapter per decision you face, playbooks for two players versus a full table and for leading, level, or behind, ten popular beliefs that lose, and twenty puzzles. A code at the end of every chapter leads here.

Your coach

It answers rules questions out of Hasbro's 2024 sheet, says plainly which four questions Hasbro has never settled, and gives every strategy number with its player count and its margin. It will not invent a number.

The research

An exact rules engine for 2 to 5 players, cross-checked against an independent engine; every strategy claim from Reddit, BoardGameGeek, and the strategy sites tested at 20,000 games a cell; a strategy evolved over millions of cloud games; and a search agent that shows where the remaining edge lives.

Deal World Championship

The first ever, unofficial. Online qualifiers played as duplicate deals: every table gets the identical shuffle in the same seat order, then rotates, so the standings measure how you played the same cards as everyone else. A live final with the broadcast table and every hand shown to the audience.

Leave your name to hear when qualifiers open, and tell us what else you'd play.
