Sudoku rules are simple, but they require attention. The player must complete all empty spaces in the grid with numbers from 1 to 9.
The three essential rules
- Each row must have numbers from 1 to 9, without repeats.
- Each column must have numbers from 1 to 9, without repeats.
- Each 3x3 box must have numbers from 1 to 9, without repeats.
Does Sudoku require calculation?
No. Sudoku uses numbers, but it does not require arithmetic. The game depends on logic, observation, and eliminating possibilities.
