Sudoku Tactics is the first true competitive game played on a sudoku board. Players take turns trying to complete rows, columns, and cells while stopping their opponents from doing the same thing. Built with a steady-state design in mind, any number of players can play, although two to eight players work best. Play to a time limit (until it stops raining!) or to a point score (for tournament play)--this game fits YOUR needs. It even includes "handicap" rules to balance the game for new players!
