On your turn you draw one card, then play as many as you like:
Drag cards from your hand (or drag piles), or double-click a card to auto-play it (on touch screens, press and hold instead). Click the message bar for the move log.
Stuck in single player? The Hint button shows the best move (3 hints on easy, 2 on medium, none on hard).
Use the sound controls in this menu to set the volume or mute.
First player with no cards wins!
