Bored to play "normal" Sudokus? Try and play unusual Sudokus. Various sizes: MultiSudoku generates Sudokus for kids, normal Sudokus, and large ones for real experts. Colors: add colors to your Sudoku. Each value can appear just once per color. Colors can be placed at the same position in each block or randomly on the field. Puzzle Sudokus replace the blocks with irregular but cohesive fields. Distribution: try to solve a Sudoku which has no cell filled in the center; or one where one value is not given at all. Or another which has its given values concentrated in one corner of the field or in the center. Diagonals: and if that is not enough, add one or both diagonals. So each value can appear just once on that diagonal. MultiSudoku is the challenge for real Sudukians.
