Kyu Sudoku

Kyu Sudoku is a sudoku to rest your mind. In Japanese, 九 (kyu) means nine, and 休, also read kyu, means rest.

A wooden tray appears in front of you, in your own room, in mixed reality. Play by touch: tap a cell, tap a digit. Or swap your room for a quiet loft, at sunset or at night, with the city outside.

Puzzles that never run out

Every puzzle is created on the spot and has a single solution you can reach with logic alone. Pick one of five levels, from Easy to Master, or let Surprise choose.
