In Sudokill, two players alternate moves that consist of replacing a blank by a number. The first player is called the row player and the second is the column player. Initially, the row player can make any legal Sudoku move. Subsequently, the column player must move in the same column as the last move of the row player and the row player must move in the same row as the last move of the column player. If a player makes an illegal Sudoku move, even by accident, then that player loses.
If we represent blanks as 0s or letters and the row player moves where there is an x:
0 0 6 0 0 0 0 0 0 8 4 0 3 x 2 0 0 0 3 2 0 0 0 5 0 7 4 0 6 0 0 9 0 8 0 0 0 0 0 6 2 4 0 0 0 0 0 2 0 3 0 0 6 0 2 1 0 9 0 0 0 8 7 0 0 0 4 0 3 0 2 5 0 0 0 0 0 0 1 0 0
The the column player must replace a blank in the same column (marked with y's):
0 0 6 0 y 0 0 0 0 8 4 0 3 x 2 0 0 0 3 2 0 0 y 5 0 7 4 0 6 0 0 9 0 8 0 0 0 0 0 6 2 4 0 0 0 0 0 2 0 3 0 0 6 0 2 1 0 9 y 0 0 8 7 0 0 0 4 y 3 0 2 5 0 0 0 0 y 0 1 0 0
Suppose the column player chooses the one marked by an upper case Y:
0 0 6 0 y 0 0 0 0 8 4 0 3 x 2 0 0 0 3 2 0 0 y 5 0 7 4 0 6 0 0 9 0 8 0 0 0 0 0 6 2 4 0 0 0 0 0 2 0 3 0 0 6 0 2 1 0 9 y 0 0 8 7 0 0 0 4 Y 3 0 2 5 0 0 0 0 y 0 1 0 0
The row player must then move in one of the positions marked with a z:
0 0 6 0 y 0 0 0 0 8 4 0 3 x 2 0 0 0 3 2 0 0 y 5 0 7 4 0 6 0 0 9 0 8 0 0 0 0 0 6 2 4 0 0 0 0 0 2 0 3 0 0 6 0 2 1 0 9 y 0 0 8 7 z z z 4 Y 3 z 2 5 0 0 0 0 y 0 1 0 0
Toward the end of the game, the following rules prove important: If there are no blanks in the column where the row player last moved, then the column player may move anywhere. Likewise, if there are no blanks in the row where the column player last moved, the row player may move anywhere.
