Skeedoku: Free Online Sudoku
Play number-placement puzzles using row, column, and box logic, with notes for possible values.
How to play
- Fill each row, column, and outlined box with every number from 1 to the board size, without repeats.
- The starting clues cannot be changed. Select an empty cell, then enter a number using the keyboard or number buttons.
- Use Notes mode to record possible values without filling the cell. Remove candidates as you rule them out.
- Complete every cell correctly to win. Mini boards use smaller number ranges and boxes; standard boards use 1–9.
A quick example
If a standard row contains every digit except 7, its remaining empty cell must be 7. Check the column and box too.
