Forty Thieves Solitaire is a popular version of Solitaire that is now available for Android users. The objective of the game is to place all the cards in each suit in stacks of descending suit sequence, similar to the version of Spider Solitaire that is playable on Windows. The game offers several features, including unlimited undo, auto complete to finish the game, statistics, and tablet support.

Players can either tap to move or drag and drop the cards. The game state is saved when interrupted, allowing players to resume the game from where they left off. The app is free to download and play, and it is developed by ElSayad Apps.
