Sweet Solitaire

Sweet Solitaire is classic Klondike (patience) with draw one and unlimited passes through the stock. Build the four foundations up from ace to king by suit, and build the seven columns down in alternating colours; only a king may fill an empty column. Drag cards, or just tap one and it jumps to the best place (its foundation first). Every deal is checked before you see it: a solver proves it can be won, and simply following the hints wins it too. If you do play into a dead end, the table tells you and offers to rewind to the nearest position that can still be won. Each card on a foundation scores 10; a win adds 500 and up to 300 more for finishing in few moves (the deal's par), while each undo costs 20 and a rewind out of a dead end costs 50 however far it goes. The daily deal is the same for everyone, so you can rank on the leaderboard or send a friend the very same deal.

1. Drag cards, or click one and it jumps to the best place (its foundation first).
2. Build the columns down in alternating colours and the foundations up from A to K; only a K fills an empty column.
3. Click the stock (or Space) to draw; ↶ or Z undoes (−20); when all cards are face up, the gold button (or A) finishes for you. H shows a hint.
