Sudoku — MyCLI

1

Two dailies, one per size: a 9×9 with 25 givens and a 4×4 sprint with 8. Free play comes in both sizes (9×9: 20–40 givens, 4×4: 8–12).

2

No digit may repeat in a row, a column, or a box — 3×3 on the 9×9 boards, 2×2 on the 4×4 boards.

3

Clashing digits stay on the board, highlighted in red until you fix them.

4

Five hints per puzzle. Each reveals one correct digit — and puts the board on the assisted list.

One of each.
