Doctor Who: SuDocWho (2005)

Each Doctor can only appear one time in each row, column and 3x3 square. The Doctor Who SuDocWho game is a Sudoku game with nine Doctors. The same rules apply as in a normal Sudoku game. Instead of nine numbers nine Doctors can be added. Completing the puzzle reveals the next doctor.
