Solving Techniques
Advance beyond the basics with bite-sized tactics tailored to Mini Sudoku grids, from easy warm-ups to sudoku hard brain workouts.
Fundamentals
- Scan for naked singles — cells where only one candidate fits after marking conflicts.
- Use pencil marks consistently, updating notes whenever you confirm a value.
- Look for missing digits within a region to quickly place hard-to-find numbers.
- After each placement, sweep the affected row and column to spot immediate conflicts or new singles.
Intermediate
- Spot hidden singles: when a candidate appears only once in a row, column, or region, it’s the answer.
- Leverage pairs — if two cells share the same candidate pair, eliminate that pair elsewhere in the unit.
- Compare row and column patterns to uncover contradictions and drive progress.
- Apply box-line reduction: when a candidate in a region is confined to one row or column, remove it from the rest of that row or column.
Speed & Habits
- Solve 4×4 boards as warm-ups before diving into streak or timed runs.
- Group similar moves to reduce back-and-forth between pencil marks and placements.
- Practice daily to recognize patterns, finish LinkedIn-style puzzles faster, and hit new streak milestones.
