Strategy is a solitaire card game which uses a deck of 52 playing cards. It belongs to the same family as Sir Tommy and Calculation, and this can be regarded as the more difficult cousin of Sir Tommy.
The cards in the deck are dealt one at a time. Aces are placed onto the foundations right away and are built up by suit. Cards that cannot yet be built are placed on any one of eight wastepiles, the top cards of which are available for play. Once a card is placed on a wastepile, the next place it will go is to foundations; it cannot be moved to another wastepile.
The game finishes after all cards are dealt to the wastepiles and all appropriate cards are built. The game is won when all cards end up in the foundations.
