MOD X is an abstract strategy game in which each player is provided 15 game pieces and 18 score markers, with the goal being to reach an established number of points (determined by the number of players). Players take turns placing a game piece on the board with the objective of creating specific scoring patterns (in the shape of either an X, a PLUS SIGN (+) or 5 in a row) while simultaneously trying to block their opponents from scoring with these patterns.
