A moderately difficult solitaire that requires a satisfying balance of skill and luck to win. The deck is dealt in seventeen groups of three overlapping cards, plus one card by itself. The aim is to release the aces and build each one up to king. Besides building on the aces, cards can be transferred between groups, provided the card being transferred is one rank higher or lower than the card it is being transferred onto. What makes this solitaire challenging is that no group of cards can ever contain more than three cards, and once a group is "used up", a new group cannot be started in its place. Careful planing is required to win at this solitaire.
