The object of this game is to build up ascending sequences of cards on the foundation piles (top) irrespective of suit.
The first foundation pile is built from Ace to King with each card being one greater than the previous. The second foundation pile goes up by two, the third by three and the fourth by fours.
For example, the second foundation pile would be built up in the following sequence:
2-4-6-8-T-Q-A-3-5-7-9-J-K
There are also four working heaps. As each card is dealt, it may be placed on any of the four heaps. Whenever a card appears that can be placed on one of the sequences, then it may be placed there instead.
Cards cannot be moved between the working heaps, but may be moved onto a foundation pile if it is the next card in the appropriate sequence.
Note that all sequences will finish with Kings, so it often pays to keep one working heap for holding the Kings until the end.
