📖 How to play

Ten columns, eight runs to finish. Line up a full suit from king down to ace and the run clears off the table into one of the slots up top.

Any card can sit on a card one rank higher, whatever the suit, so a 7 fits on any 8. To move several cards at once, though, they need to be the same suit and in order. An empty column takes anything.

Out of moves? Tap the stock to drop one card on every column; you get five of those. Undo takes back a mistake but costs a move. One suit is a warm-up, four suits is the real test.
