How to Play
Dots Sudoku: The basic rules
Fill the 9x9 grid so every row, column, and 3x3 square contains digits one through nine. Tap cells to input numbers using standard Dots Sudoku controls. If you see a white dot, those neighbors must differ by exactly one. A black dot means they differ by exactly half.
How to play Dots Sudoku effectively
Look for the gaps. If there is no dot between two cells, those numbers cannot differ by one or half. This is how to play Dots Sudoku without guessing. A common mistake is forgetting that 1 and 2 can have both dot types. Watch those edges, as the expert levels get brutal.
