About the game
Nine small 3 x 3 boxes sit inside one big 9 by 9 field. Every line across, every line down and every box has to carry the digits 1 through 9, and each digit goes in once per line and per box. That rule is the whole job.
You fill the empty cells one at a time. Read the digits already sitting in that row, that column and that box, then tap one that breaks nothing. Levels get heavier as you climb, and older levels stay reachable when you want a calmer board. Slow counting keeps your head on the grid.
How to play
- Tap an empty cell, then pick a digit from 1 to 9.
- A digit fits only once in a row, a column or a 3 x 3 box.
- Every line and every box has to hold all nine digits by the end.
- Later levels are tougher; earlier ones stay open for an easier round.
