How to play

Fill every row, every column, and every 2×3 box with 1, 2, 3, 4, 5, and 6 exactly once.

Start with easy patterns: look for a row, column, or box that is missing only one symbol.

Keyboard help

You can also use keyboard keys 1 to 6, plus Delete or Backspace to clear the selected square.

Why 6×6 Sudoku works for kids

A 6×6 grid expands the player's attention span without jumping straight into a full 9×9 board. It helps learners practice scanning longer rows and columns while still finishing puzzles in a manageable amount of time.

This page continues the children's Sudoku track at Sudoku School with the same shared skins, teaching-friendly hints, and touch-friendly layout used by the 4×4 version.
