Classic Solitaire card game. Play away all cards on the playing field.
You can move cards that are 1 higher or 1 lower in value to the open stack card (bottom right). If you cannot play a card, open up a new card by clicking on the first card of the closed deck.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
