Two full decks, one hundred four cards. Forty of them — the thieves — are dealt face-up into ten columns of four, and the other sixty-four wait in the stock. Build all eight foundations up by suit from ace to king to win.
The tableau builds down in matching suits, and here's the discipline: one card at a time. No run ever moves together, no matter how neatly it's ordered — every rescue is card-by-card labor. An empty column takes any card, and those open columns are the entire engine of the game.
The stock turns over a single card per tap, and there is no second pass. Every card that hits the waste and gets buried is a decision you already made. Forty Thieves is the biggest board in the app, and it plays like it — a long, deliberate siege.
Undo is unlimited and stacks back to the deal. If nothing can move, rewind and try a different line — or claim the board is stuck and end it there.
Double Forty Thieves deals both players the identical hundred-four-card layout and starts you together. No turns — you're both working the same siege at once, and the first to move all one hundred four cards home wins immediately.
You'll watch your opponent's foundation count climb while you work. If you both stall out — or the match clock expires — the higher count takes it, and a true tie is a draw.
Same deal, same single pass. The race is over who wastes fewer cards to the waste.
Play it quietly on your own, or race a real opponent. Quick Match seats you in seconds; private lobbies let you pick who's across the table.
Races deal both players the identical layout. Nobody draws the easier board — the only difference is how you play it.
Run a lobby untimed or on a match clock, with reconnect handling that doesn't cost you the game. Solo play whenever you just want a quiet one.
