How to Play Mini Sudoku

The rules are simple: fill the 6×6 grid so that every row, column, and each 2×3 box contains the numbers 1 through 6 exactly once. No guessing—just pure logic and satisfying “aha!” moments.

Start by looking for rows, columns, or boxes with the most numbers already filled in. Use process of elimination and keep an eye out for unique placements. As you practice, you’ll get faster and more confident with every puzzle.

How Mini Sudoku Differs from Standard 9×9

Feature	Mini (6×6)	Standard (9×9)
Grid size	36 cells	81 cells
Box shape	2×3 rectangles	3×3 squares
Digits used	1–6	1–9
Average solve time	1–3 minutes	5–40+ minutes
Techniques needed	Naked singles, hidden singles	Varies by difficulty
Difficulty range	One level	Easy through Evil

The smaller grid means fewer candidates per cell, so pencil marks are rarely needed. This makes Mini Sudoku ideal for learning the core logic of scanning rows, columns, and boxes without the overhead of managing complex notation.

Tips for Solving Mini Sudoku Faster

Start with the most-filled unit. Look for rows, columns, or boxes with 4 or 5 digits already placed — the remaining cells are trivial.
Use cross-hatching. Pick a digit (say, 3) and scan the grid to find where it’s already placed. The remaining rows, columns, and boxes narrow its placement quickly.
Don’t overthink it. Mini Sudoku rarely requires anything beyond simple scanning. If you’re stuck, you’ve likely overlooked a constraint.
