<P> In 2012, researchers used evolutionary computation methods to create winning FreeCell players . </P> <P> The FreeCell game has a constant number of cards . This implies that in constant time, a person or computer could list all of the possible moves from a given start configuration and discover a winning set of moves or, assuming the game cannot be solved, the lack thereof . To perform an interesting complexity analysis one must construct a generalized version of the FreeCell game with 4 × n cards . This generalized version of the game is NP - complete; it is unlikely that any algorithm more efficient than a brute - force search exists that can find solutions for arbitrary generalized FreeCell configurations . </P> <P> There are 52! (i.e., 52 factorial), or approximately 8 × 10, distinct deals . However, some games are effectively identical to others because suits assigned to cards are arbitrary or columns can be swapped . After taking these factors into account, there are approximately 1.75 × 10 distinct games . </P>
