The objective of this game is to move cards to the foundations from ace to king. Figure 1
A single card may be moved from the top of a tableau column to an empty free cell. Cards can be moved to the foundations from either the top of a tableau column or a free cell. Cards placed on the foundation must be of the same suit and one rank higher than the previous card. If the foundation is empty, an ace is placed. Cards from the top of a tableau column or from a free cell can be moved to the top of another tableau column. The moved card must be one rank lower than the top card of the destination tableau column and of the opposite color (red on black or black on red). Figure 2
A descending sequence of alternating red and black cards can be selected and moved as a group. Although only one card can physically be moved at a time, the program determines whether a group move is allowed based on the following formula.
Number of cards to move ≦ (1+N)×2M
N: Number of empty free cells
M: Number of empty tableau columns
If the destination column is empty, it is not counted among the empty tableau columns in the above formula. Figure 3
The game ends when all cards are moved to the foundations. Figure 4
