HOW TO PLAY
Sudoku is simple to learn and endlessly satisfying to master. Fill every row, every column, and every 3x3 box so that each digit from 1 to 9 appears exactly once. Tap a cell, choose a number, and use a hint whenever you want a gentle nudge. Turn on notes to pencil in candidates, and let the clean candy board keep everything easy to read.
Every skill level is welcome. Beginners can start with gentle, well-hinted boards that teach the basics, while seasoned solvers can jump straight into hard and expert grids that demand real strategy. As you improve, the smart hints step back and let your own logic lead.
Candoku is more than a game - it is a small daily ritual for a calmer, sharper mind. A few quiet minutes of number logic can help you focus, slow down, and step away from a noisy feed. Because everything works offline, it is the perfect companion for flights, commutes, waiting rooms, or a relaxing wind-down before bed - just you and the puzzle.
WHO IT IS FOR
Candoku is perfect for lifelong Sudoku lovers, newcomers learning the basics, puzzle and brain-game fans, and anyone who wants a calm, screen-friendly mental workout during a commute, a coffee break, or a quiet evening at home.
