What makes Mini Sudoku different from classic Sudoku?

Same rules, smaller grid. Mini Sudoku uses 6×6, 8×8, or 10×10 boards instead of the classic 9×9. The logic patterns are the same — you just finish faster, which is part of the appeal.

Is Sudoku good for your brain?

Probably. Sudoku is a focus and pattern-recognition exercise, and there's research suggesting puzzle games help maintain those skills. We won't promise it changes your life — it's mostly just a fun thing to do for a few minutes.

How often should I play?

Whatever feels right. A short daily puzzle is enough to keep getting better at the patterns. The streak counter helps if you like that kind of nudge.

Is Mini Sudoku good for beginners?

Yes. The 6×6 grid is much friendlier than 9×9 — fewer cells, fewer candidates to track. It's a good way to learn the basics before stepping up.

Can I play on my phone or tablet?

Yes. The whole site is built for phone first. Big tap targets, no fiddly controls.

Yes. Hints, pencil marks, and conflict highlighting are all optional toggles. Use them when you want help, leave them off when you don't.

Will you add larger Sudoku boards?

Solving Techniques

A few patterns that make Mini Sudoku faster. Start with the fundamentals; the rest is optional.

Fundamentals

Naked singles: a cell where only one digit fits.
Use pencil marks. Update them every time you place a value.
Look at each region for the digit that's missing — it's often easier than scanning the whole board.
After every placement, re-check the row and column for new singles.

Intermediate

Hidden singles: a digit that can only go in one cell within a row, column, or region.
Naked pairs: when two cells share the same two candidates, those digits can't go anywhere else in the unit.
Compare row and column patterns to find contradictions early.
Box-line reduction: if a digit in a region is confined to one row or column, remove it from the rest of that row or column.

Speed & Habits

Use 6×6 as a warm-up before timed runs on bigger grids.
Place all candidates for one digit at a time. It's faster than scanning cell by cell.
Play daily. Pattern recognition gets noticeably faster within a week.
