About game
In Sudoku Domino, you'll find tranquil logic challenges where domino tiles with dots substitute for numbers. Your task is to complete each row and column so that each value shows up just once.
Begin with a 4×4 grid and progress to larger ones, up to 9×9. Collect coins for victories and use them in the shop to enhance your grid and discover new domino skins.
Choose between two modes:
- Infinite: tackle as many puzzles as you wish.
- Calendar: enjoy a fresh puzzle each day.
How to play
1. To start, press Play on the main screen or choose a date in the calendar.
2. Pick an empty space on the grid.
3. Select a domino half at the bottom — 0 stands for a blank half.
4. Complete the grid so that every row and column has each number exactly once. This rule applies to 4×4, 6×6, 8×8, and 9×9 grids.
5. Incorrect answers won't be placed and will count as mistakes. You can make up to five mistakes per puzzle.
6. Use the bottom tools: undo, pencil, erase, check.
7. Watch a short ad to get a hint that fills one cell.
8. Earn coins to upgrade your grid and buy skins in the shop.
