About the game
Zion Sudoku is a clean, calm sudoku made to be easy on the eyes, on phone and computer. Choose Easy, Medium, Hard or Expert. Every board has a single solution, and its level comes from the logic it needs, not just from how many numbers it gives you.
Write notes, undo any move and use three hints per board that explain why a number fits. As on paper, the game only marks a number that repeats in its row, column or box, and tells you where; whether a number is right shows only when you ask for a hint. Play with no limit, or end the board at the third repeat. The puzzle of the day is the same for everyone and builds a streak, and every solved board adds its points to the weekly ranking.
How to play
- Tap a cell, then a number to fill it.
- Turn on Notes to jot small candidate numbers.
- Each row, column and 3×3 box holds 1 to 9 once.
- Stuck? A hint places the next number and says why.
- Fill the whole grid to solve the board.
