How It Plays
Every row, column, and box must contain 1 through 9
Sudoku is not about speed. It is about noticing which numbers already exist and using that information to eliminate the remaining spaces.

Fill the grid from 1 to 9, and let twelve stages slowly raise the logic pressure.
Clearer Progress
- Start with rows, columns, or 3x3 boxes that already have fewer empty spaces.
- The same number cannot repeat in the same row, the same column, or the same box.
- If one spot feels uncertain, leave it for later and come back once the grid gives you more clues.
