Retrograde analysis is a technique employed to determine which events occurred leading up to a given situation.

The term has its origins in chess, where one must deduce the moves of play that led to a certain position of the game. But it can also be applied to other games such as Reversi, Tic Tac Toe, Dots and Boxes, Scrabble, Checkers, Bridge, Monopoly, etc.

In general, the term refers to "backward reasoning" applied to a specified outcome (that often appears to be unexpected or irrational), to trace the actions or intentions that led to it.
