Simple Sudoku - Play Online
Classic number puzzle. Pure logic. Simple Sudoku strips away the fluff. Just you, a 9×9 grid, and digits 1 through 9. Brain training? Check. Endless replayability? Check. This is Sudoku at its core.
How to Play Simple Sudoku
The mission is simple. Fill the grid. Every row needs 1-9. Every column needs 1-9. Every 3×3 box needs 1-9. No repeats. Solve the puzzle without breaking the rule. That's it.
The Core Mechanic
Click a cell. Pick a number. Drop it in. Watch for conflicts. Red flags mean duplicate digits in the same row, column, or box. Erase mistakes. Try again. The grid won't lie to you.
Progression & Difficulty
Start easy. Build confidence. Move to medium when patterns click. Hard mode? That's where the brain sweats. Simple Sudoku offers three difficulty tiers. Each step up removes more pre-filled numbers. More blanks. More challenge.
Strategy Tips
Scan rows first. Hunt for missing singles. Cross-reference columns. Lock down the 3×3 boxes early. Stuck? Use the hint system. It reveals one correct digit. Don't spam hints. Save them for dead ends. Process of elimination wins games.
