Mini Sudoku vs Sudoku: Which One Should You Play?
23 October 2026 · 2 min read
Mini Sudoku or classic Sudoku? Both use the same idea, so the real question is how much time and attention you want to spend. Here is how they differ and which one to pick for which moment.
The rules are the same, the grid is not
In a classic Sudoku the grid is 9 by 9, split into nine boxes of 3 by 3. Every row, column and box holds the numbers 1 to 9 exactly once. Mini Sudoku shrinks that to 6 by 6, with six boxes of 2 by 3 and the numbers 1 to 6. Same logic, far fewer squares.
How long does each one take?
On PuzzleDose the scoring assumes a typical Mini Sudoku takes around 80 seconds and a typical Sudoku around five minutes. That is the whole difference in a nutshell: Mini Sudoku fits between two meetings, Sudoku asks for a proper break.
Which one should you play?
- Pick Mini Sudoku if you are new to sudoku, short on time or want a quick win. With only six numbers it is easy to see what is missing from a row, column or box.
- Pick Sudoku if you want to stretch your mind. The bigger grid has more room for techniques like scanning for a number across several boxes.
- Play both if you like a warm-up. Mini Sudoku first, then the big one, works well.
Habits that help in both
- Scan one number at a time across the whole grid ("where can every 7 go?") instead of looking at one square after another. It is usually faster.
- Start with the rows, columns and boxes that are nearly full: they have the fewest possibilities.
- Use notes. On PuzzleDose you tap a number again to turn it into a small note, and once more to clear it.
- Every puzzle can be solved by logic alone, so if you feel the urge to guess, look for another number to place instead.
Each day brings a new Sudoku and a new Mini Sudoku, free to play without an account. If you like both, try Tectonic next: it uses the same number logic on a grid of irregular regions.
