A strategy game or strategic game is a game (e.g. video or board game) in which the players' uncoerced, and often autonomous decision-making skills have a high significance in determining the outcome. Almost all strategy games require internal decision tree style thinking, and typically very high situational awareness.

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.
