What is Mini Sudoku?

Mini Sudoku is a streamlined, faster-paced variation of the classic 9x9 Sudoku puzzle, typically played on a 6x6 grid. It offers all the logical depth of traditional Sudoku but can be solved in a fraction of the time.

Because the grid is smaller, Mini Sudoku is perfect for beginners learning the ropes of logical deduction, or for experts looking for a quick mental sprint during a coffee break.

How to Play

The 6x6 grid is divided into six 2x3 sub-grids. Your goal is to fill the empty cells with numbers from 1 to 6.

Every row, every column, and every 2x3 sub-grid must contain the numbers 1 through 6 exactly once. No number can repeat in a row, column, or block.

Strategy & Tips

Start by scanning for rows, columns, or blocks that are already mostly filled. If a row has five numbers, the missing number is trivial to deduce.

Use 'cross-hatching' to scan rows and columns for a specific number to see where it must go in a block. Because the grid is only 6x6, cross-hatching is extremely fast and effective.

Benefits

Mini Sudoku is a fantastic entry point for children and beginners to develop critical thinking and problem-solving skills.

It provides a quick dopamine hit from completing a puzzle, reducing stress while keeping cognitive functions sharp and focused.
