How to Play 6×6 Sudoku

The goal of a 6×6 Sudoku is to fill the grid so that every row, column, and 2×3 box contains the numbers 1 through 6 without repetition.

Rules

Each row must contain the numbers 1-6 without repeating
Each column must contain the numbers 1-6 without repeating
Each 2×3 box must contain the numbers 1-6 without repeating
Some cells start with given numbers
Use logic to deduce the remaining numbers

Tips

Look for singles: Check rows, columns, or 2×3 boxes to find numbers that can only fit in one place
Use elimination: Remove numbers that already appear in the same row, column, or box
Notes mode: Use the notes feature to mark possible numbers and support your logic
Start simple: Fill in the obvious numbers first, then work through the tougher spots
