Move all 52 cards to the four foundations, building each suit up from Ace to King.
On the seven piles, build down in alternating colors. Only a King, or a run led by a King, fills an empty pile.
Tap or click a card to send it to its best spot (its foundation whenever it can go up), or drag a card or a whole run. A double-tap or double-click sends a card up too.
Tap the stock to draw; when it runs out, tap it again to turn the waste over.
Score: waste to pile 5, to a foundation 10, turning a card over 5, foundation back to a pile −15.
