Mini Sudoku Techniques for Faster Solves
Build a solving toolkit that scales from quick 4×4 warm-ups to LinkedIn-style 6×6 puzzles. Apply pencil mark tactics, hidden singles, pointing pairs, and speed drills to crush daily Sudoku challenges.
Beginner Mini Sudoku Techniques
Start with these rock-solid fundamentals to gain confidence on 4×4 boards and keep mistakes out of 6×6 grids.
Fundamental #1
Scan for naked singles — cells where only one candidate fits after marking conflicts.
Fundamental #2
Use pencil marks consistently, updating notes whenever you confirm a value.
Fundamental #3
Look for missing digits within a region to quickly place hard-to-find numbers.
Fundamental #4
After each placement, sweep the affected row and column to spot immediate conflicts or new singles.
Intermediate Tactics for 6×6 Grids
These moves unlock harder puzzles and mirror the techniques used by LinkedIn Mini Sudoku speed-solvers.
Intermediate #1
Spot hidden singles: when a candidate appears only once in a row, column, or region, it’s the answer.
Intermediate #2
Leverage pairs — if two cells share the same candidate pair, eliminate that pair elsewhere in the unit.
Intermediate #3
Compare row and column patterns to uncover contradictions and drive progress.
Intermediate #4
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.
Advanced Mini Sudoku Plays
Ready to tackle sudoku hard or streak leaderboard boards? Layer these tactics after you master the fundamentals.
Locked Candidates
When a candidate only appears in one row or column within a region, eliminate it from the rest of that row or column to force progress.
Pointing Pairs & Triples
If a pair (or trio) of cells inside a region share the same candidate, remove that candidate from other cells in the intersecting row or column.
Simple Coloring (6×6)
Assign two colours to a candidate pair across the grid. If one colour causes a contradiction, eliminate it to solve the pattern quickly.
