Clone of the Solitaire game in Shenzhen I/O.

The goal is to remove all the cards from the board.

The three slots in the top left corner can be used to temporarily store a card.

If 4 aces of the same colour are exposed and a "temporary slot" is available, all four of those aces can be permanently moved to that slot.

Cards can be stacked in descending order and with alternating colours. Cards can not be placed on aces.

Cards can be permanently placed in the top right "permanent slots" in ascending order by colour.
