Sudoku Queen

Sudoku Queen is classic Sudoku, crafted like a wooden puzzle board on a quiet table. Every puzzle has exactly one solution, so every number you place can be worked out - no guessing, ever.

Fill each row, column and 3x3 box with the numbers 1 to 9. That is the whole rule. The fun is in the reasoning - and in the moment a row, a box or the whole board locks into place.

FEEL EVERY BREAKTHROUGH
- Complete a row, column or 3x3 box and a wave of light sweeps out from the number you just placed.
- Close several at once for a combo bonus.
- Finish the board and the whole grid lights up with a shower of confetti.

A NEW PUZZLE EVERY DAY

- Difficulty builds through the week, from a gentle Monday to a Master-level Sunday.
- Solve it to mark the day complete.

FOUR DIFFICULTY LEVELS
