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 row or column can only go inside one region, remove it from the rest of that region.
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.
