🎯 How to Play a Sudoku 6×6 Board
The rules of this grid are incredibly intuitive. If you are looking for a sudoku 6×6 easy warm-up, simply select “Easy” from the dropdown above and follow these core rules:
- The Numbers: Instead of 1 through 9, you will only use the numbers 1, 2, 3, 4, 5, and 6 to fill the board.
- Rows & Columns: Every horizontal row and vertical column must contain the numbers 1-6 exactly once.
- The Rectangular Blocks: The board is divided into six distinct 2×3 rectangular blocks. Each of these blocks must also contain the numbers 1 through 6 without repeating.
- Smart Controls: Select an empty cell on the board, then click the number on the keypad below to place your answer.
