Forty Thieves with unlimited deals
Forty cards in ten columns, two full decks, and a rule book with no mercy: one card at a time, same-suit builds, one trip through the stock.
This game starts a fresh deal after a reload. Use the deal number to replay the same layout.
Keyboard: Tab to a card or pile, then press Enter or Space to select it or make the move.
The played, win rate and W–L figures cover up to the 400 most recent deal outcomes stored in this browser, and the Daily streak continues across older outcomes. A deal is recorded when you win or leave it after making a move, so a dead end that Undo can still rescue does not count as a loss. The Daily counts once per UTC date, and replaying a recorded deal never adds another play. A later win on a lost deal replaces the loss. Unlimited results are kept separate.
How to play
Eight foundations climb ace to king by suit, and all one hundred and four cards belong there. On the tableau, build down in suit, moving a single card at a time. Any card may claim an empty column, and empty columns are the only spare room you get. The stock deals one card per tap and never recycles, so every draw is a commitment. This is the classic expert's solitaire, and raw win rates run low. Undo keeps your last 200 moves, even after you get stuck, so you can study a deal and try another line.
Questions people ask
Why is Forty Thieves so hard?
Single-card moves and a one-pass stock leave no slack. A buried card stays buried until you open an empty column, so plan space for buried cards before using the stock.
Why are there eight foundations?
Two full decks are in play, so each suit builds twice. Either matching foundation accepts a card.
Any opening advice?
Empty a short column early, even at some cost, because it's the only place to stage cards. Don't deal from the stock while any tableau move improves your position.
