Forty Thieves is a free browser game on SolitaireFelt, built for a short break that can stretch into a long session. There is no download, no sign-in, and no backend: the puzzle runs in this tab and your best results stay in local storage on your device. That keeps the page fast, private, and easy for Google to crawl as a real game page rather than an empty iframe.
Two decks, ten columns, build same-suit down. Foundations ace to king. It sits in our Solitaire & Cards collection because people already search for this mechanic by name. The rules below match the familiar version of the game, with original board art and a full felt table for play.
How to play Forty Thieves
Two full decks, ten tableau columns. Build down in the same suit. Eight foundations take ace through king in suit — two per suit. Empty columns accept any card.
Tips
Do not bury low aces in deep columns. Two foundations per suit means you can park a deuce early.
