Match

Match is Concentration with a twist. Instead of having to find two identical pictures in a grid of tiles place face-down, the player must find two cards whose sum equals 63. Otherwise the rules are identical to Memory/Concentration, players take turns flipping a pair of tiles in the hope of having a match (the sum of 63 in this case). Each correct match earns the player a point and also an additional turn. The game can be played solitaire, with up to four players, or against the AI with up to nine different difficulty levels.
