Ninoma: X-Sudoku & Classic
Sudoku with a difficulty label that means something.
Sudoku on a 9x9 grid in two variants: Classic, and X-Sudoku where both diagonals must also hold 1-9. Tap a cell, enter a digit from the pad; pencil notes, undo and erase are available.
What makes it different
- Puzzles are generated on the device and graded by the solving techniques they actually require, from singles up to Jellyfish.
- Six difficulty tiers, each earned by the logic the puzzle needs rather than by how many digits were removed.
- Every puzzle is checked for a single solution before it is handed to you.
- Three-step hints: the area that proves the move, then the cell, then the number.
