How to Play Mini Sudoku (6x6 Format)
Master the compact 6x6 Mini Sudoku format with 2x3 boxes - perfect for quick puzzle sessions.
Step 1: Understand the Grid
The 6x6 grid is divided into six 2x3 boxes (2 rows, 3 columns each). This compact format is perfect for quick puzzle sessions and brain training.
Key Rule: Each row, column, and 2x3 box must contain numbers 1-6 exactly once.
Step 2: Start with Singles
Look for cells where only one number can fit. In a 6x6 grid, scan each row, column, and 2x3 box to find cells with only one possible number.
Pro Tip: Start with the most filled rows, columns, or boxes first.
Step 3: Use Notes Wisely
Click the Notes button to mark possible numbers in each cell. This helps track candidates and spot patterns more easily in the 6x6 format.
Technique: When you place a number, remove it from notes in the same row, column, and 2x3 box.
Step 4: Master 2x3 Boxes
Focus on the 2x3 boxes - this is what makes Mini Sudoku unique and compact. Each box must contain numbers 1-6 exactly once.
Strategy: If a box needs only 1-2 numbers, check which cells can accommodate them.

Common Mini Sudoku Mistakes to Avoid
Learn from these frequent beginner errors to improve your solving speed and accuracy in Mini Sudoku puzzles.
Ignoring the 2x3 Box Rule
Many beginners focus only on rows and columns, forgetting that each 2x3 box must also contain numbers 1-6 exactly once. This is the most common error in Mini Sudoku.
Solution: Always check all three constraints (row, column, and 2x3 box) before placing a number. Use visual scanning to identify which numbers are missing in each box.
Guessing Instead of Logic
Rushing to fill cells without proper analysis often leads to contradictions and unsolvable puzzles. Every Mini Sudoku has exactly one solution.
Solution: Take time to analyze each cell systematically. Use the elimination method and only place numbers when you're certain they're correct.
Not Using Notes Effectively
Trying to solve Mini Sudoku without tracking possible numbers in each cell makes it much harder to spot patterns and logical deductions.
Solution: Use the Notes feature to mark possible candidates in each cell. Update notes as you place numbers to maintain accuracy.
Overlooking Single Candidates
Missing cells where only one number can fit is a common oversight that slows down solving progress significantly.
Solution: Regularly scan for "naked singles" - cells where only one number is possible based on row, column, and box constraints.
Frequently Asked Questions About Mini Sudoku
Get answers to the most common questions about Mini Sudoku rules, strategies, and benefits.
What is Mini Sudoku and how is it different from regular Sudoku?
Mini Sudoku is a 6x6 version of the classic 9x9 Sudoku puzzle. Instead of using numbers 1-9, you only use 1-6. The grid is divided into six 2x3 boxes instead of nine 3x3 boxes. This makes it perfect for beginners, children, or anyone wanting a quicker puzzle experience that takes just 2-5 minutes to solve.
What are the rules of Mini Sudoku?
The rules are simple: Fill the 6x6 grid so that each row, each column, and each 2x3 box contains the numbers 1, 2, 3, 4, 5, and 6 exactly once. No number can be repeated in any row, column, or 2x3 box. Every puzzle has exactly one correct solution that can be found through logic alone.
Is Mini Sudoku suitable for children and beginners?
Absolutely! Mini Sudoku is specifically designed to be more accessible than traditional Sudoku. The smaller 6x6 grid is less overwhelming for beginners, and the reduced complexity makes it perfect for children aged 6 and up. It's an excellent way to develop logical thinking, pattern recognition, and problem-solving skills without the intimidation factor of larger puzzles.
How long does it take to solve a Mini Sudoku puzzle?
Most people can solve an easy Mini Sudoku in 2-3 minutes, medium puzzles in 3-5 minutes, and hard puzzles in 5-8 minutes. Beginners might take longer initially, but with practice, solving times improve significantly. The quick completion time makes Mini Sudoku perfect for short breaks, commutes, or whenever you have a few spare minutes.
What are the cognitive benefits of playing Mini Sudoku?
Regular Mini Sudoku practice enhances working memory, improves concentration, develops logical reasoning skills, and strengthens pattern recognition abilities.
