Sudoku the way it should be: calm, fair and made for people who love logic.

NO ADS WHILE YOU PLAY
Nothing ever pops up in the middle of a puzzle and there are no banners next to the number pad. The game is free; free players may see an ad between games, never during one. Premium removes them completely.

UNLIMITED MISTAKES ALLOWED
Mistakes are part of solving. Make as many mistakes as you need, fix them and finish your puzzle. A slip you correct right away doesn't count. Prefer to find your own mistakes? Turn automatic checking off, check only when you want to, and earn a small rating bonus.

HINTS THAT TEACH
Stuck? A hint doesn't just fill in a number. First it checks for a mistake, then it nudges you toward the next step, then it shows the logic behind it in plain words: "4 and 8 can only go in these two cells of row 2, so no other cell of row 2 can be 4 or 8." Every technique you meet goes into your own technique library, so you get better with every puzzle.

EVERY PUZZLE IS SOLVABLE WITH LOGIC
Each puzzle has one solution and can be finished without guessing. Difficulty comes from the hardest technique it needs: Easy, Medium, Hard and Genius.

DAILY CHALLENGE
A new puzzle every day, the same for every player at your level. Keep your streak going and watch your calendar fill up.

A RATING THAT GROWS WITH YOU
Two short placement puzzles find your level. From Newcomer to Master, your rating follows how you really solve, and a perfect solve never costs you points.

MEDALS AND RECORDS
Earn bronze, silver and gold medals for clean solves, streaks, speed and more. Track your best times and statistics.

GENIUS GAUNTLET
Three Genius puzzles every month, the same for everyone, for players who want a real challenge.
