Sudoku 4×4 is a smaller size variant of Sudoku. Despite that size, it is more difficult than you may think and includes all the interesting parts of normal Sudoku. Sudoku 4×4 takes less time to solve. So it is suitable for killing time. I also recommend it to people whom normal Sudoku is too difficult for.
We make all puzzles have only one solution.
