Playing Double Klondike Solitaire means double the cards—104 instead of the usual 52. Sounds tough right? This puzzle is actually pretty simple to solve…with eight foundation cells instead of four, you’ve got loads of options to keep things moving. You can draw one or three cards (drawing three makes it a bit harder), and if you mess up, just hit undo as much as you like. The rules? Almost the same as classic Solitaire, so it’s perfect for new players to jump in and get a feel for the game without getting overwhelmed.
