Solitaire

Build the four foundations from ace to king by suit. In the tableau, stack cards downward in alternating colors, and move face-up runs between piles; only kings may claim empty piles. Tap a card to pick it up, tap a destination to drop it — tap the same card twice to send it straight to its foundation. Draw from the stock when you're stuck; recycling the waste costs 100 points in draw-one. When everything is face up, Auto-finish sweeps the rest.

Keyboard: D/Space draw · F send to foundation · A auto-finish · U/Ctrl+Z undo · Esc deselect
