About the game
A 9x9 grid split into nine small blocks, with a few digits already in place. You fill every empty cell with 1 to 9 so that no digit repeats in any row, column or block. Pick a difficulty first, and watch the mistake counter as you go.
How to play
- Tap or click an empty cell, then choose a number to place in it.
- Use the Notes button to jot down possible numbers without committing to one.
- Each digit may appear only once in every row, column and 3x3 block. Wrong placements count as mistakes.
