About this game

Sudoku Puzzle is a free online Sudoku game. No registration, play instantly in your browser.

The classic mode offers four difficulty levels: Easy for beginners, Medium for steady practice, Hard for experienced players, and Expert for those who seek a real challenge. Additional game modes expand the standard rules: X-Sudoku adds diagonal constraints, Windoku introduces extra regions on the grid, Killer Sudoku requires groups of cells to meet a target sum, and Kropki adds ratio and difference markers between adjacent cells.

Every puzzle has exactly one solution, reachable through pure logic — no guessing required. If you get stuck, a step was missed somewhere, and it can always be traced back.

Sudoku Puzzle is also a competitive experience. Leaderboards track rankings by level, score, and wins. Personal profiles store game history and detailed statistics. The chat lets players connect, share strategies, and challenge each other.

This game runs on Playgama. Its internal scores are managed by the game provider and are not available to StreamWave's database.
