Your daily moment of clarity.
One fresh puzzle. A shared challenge. Come back each day and make a little time for yourself.
A fresh puzzle arrives every day at 00:00 UTC. Everyone plays the same board.
One puzzle. A fresh start.
A new medium-difficulty Sudoku is released at midnight UTC. Everyone receives the same puzzle for the day, so you can make it a shared challenge or keep it as a quiet daily ritual.
Your progress is saved by date on this device. You can leave and return without starting over, and if midnight arrives while you are solving, the puzzle already on your board stays in place.
Start by scanning the fullest units and make one clear move. If you get stuck, candidate notes or a short break can help; there is no streak to protect and no need to race the timer.
How we make our Sudoku puzzles
We create our puzzle packs with our own Sudoku generator. Starting from a completed grid, it removes clues only when exactly one solution remains. Each puzzle is checked again before joining a pack.
Difficulty follows the logical techniques needed to solve the puzzle, rather than just the number of empty cells. Easy starts with single candidates; higher levels introduce techniques such as pairs, triples, X-Wing, and Swordfish.
Hints that explain the reasoning
Our hints explain the reasoning behind the next move, including candidate eliminations when needed. Use them to understand a pattern and try it yourself on the next puzzle.
