Description
The classic number puzzle, made to be calm and comfortable to play with a finger.
Pure logic. Every sudoku has exactly one solution and can be solved step by step, never by trial and error. The level is set by the techniques it needs, not by how many numbers are missing.
Hints that teach. When you get stuck, the hint shows you where to look and why, instead of just giving you the number. That is how you move up a level.
Three modes. Classic (Easy, Medium, Hard and Expert), a Daily challenge with the same sudoku for everyone each day, and Zen, with no timer.
Genuinely calm. No ads, no purchases and no accounts. Your games, stats and achievements stay on your device.
For everyone. Dark, light and high-contrast themes, large numbers, left-handed controls and a reduce-motion option.
