Squary Movey

A Sudoku variant on a 9 x 9 spaces grid. Players may move their pawn (numbered from 0 to 8) one space onto an adjacent vacant space, if in the column and row and 3 x 3 zone this number is not present yet. The player who first has 5 of his pawns in the indicated area (varies according to the number of players) wins. Variation 1: You must have 6 instead of 5 pawns in the designated area. Variation 2: Throw the die to determine which pawn is to be moved.
