4 foundation piles: Build up from Ace to King in the same suit.
8 cells: Each cell holds one card. A cell card can be played to the foundations or the tableau. At the start of the game, every cell is dealt one card.
8 tableau piles: Build down within the same suit. The top card can be played to the foundations, an empty cell, or another tableau pile. Only one card moves at a time, so use empty cells to shuffle a longer run over card by card. Only Kings (or a King with cards on top of it) may fill an empty pile. Once the cells are dealt, the rest of the deck fills the eight piles face-up: the first four piles get six cards each, and the last four get five.
