Fast solving isn’t a different skill from accurate solving — it’s the same logic, with less wasted motion. These are specific habits, not general encouragement.
Fix your scan order
Random scanning wastes time. Pick a consistent path — rows top to bottom, then columns left to right, then boxes — and run it the same way every time you sit down with a new grid. A fixed order means you’re never re-checking the same cell twice out of uncertainty about whether you already looked at it.
Solve singles before anything else, every time
Naked and hidden singles cost almost nothing to find once you’re used to the scan, and placing them quickly often reveals more singles immediately after. Resist the urge to jump to a pair or a locked candidate you’ve spotted while there are still obvious singles sitting unplaced — clear them first, then reassess.
Keep notes minimal, not exhaustive
Writing every candidate into every cell takes real time and most of it won’t matter. Mark candidates only in the specific area where you’re stuck, and only once singles have stopped producing results there. A board half-covered in pencil marks is slower to read than one with notes only where they’re earned.
Recognize patterns, don’t re-derive them
Once you’ve found a naked pair or a locked candidate a few dozen times, the shape becomes recognizable at a glance instead of something you reason through step by step. That recognition is most of what separates a fast solver from an accurate-but-slow one — it comes from repetition, not from a trick.
Don’t second-guess a placement you’ve already verified
If you checked a digit against its row, column, and box and it’s clean, write it down and move on. Going back to re-verify placements you’ve already confirmed is one of the most common places solvers lose time without gaining accuracy.
Use the timer as feedback, not pressure
Our board has a built-in timer with pause — use it to notice which difficulty levels are actually taking you longer than you’d guess, rather than to race against yourself mid-puzzle. Reviewing your own stats (games played, average time per level) tends to be more useful for actually getting faster than trying to go faster in the moment.
