Tecniche di risoluzione per il livello Esperto
| Tecnica | Descrizione | Livello |
|---|---|---|
| Region Overlap Analysis | Each Hyper region overlaps with two standard 3×3 boxes. Any digit placed in the standard box cells within a Hyper region also constrains the full Hyper region. | Principiante |
| Extended Naked Singles | With 13 regions total (9 standard boxes + 4 Hyper), naked singles appear far more often than in classic Sudoku. | Principiante |
| Pointing Pairs (Hyper) | If a digit in a Hyper region is locked to one row or column of that region, eliminate it from the rest of that row or column. | Intermedio |
| Hyper–Box Interaction | A digit placed in a standard box cell that falls inside a Hyper region removes that digit from the entire Hyper region. | Intermedio |
| X-Wing across Hyper | Hyper regions can serve as a fifth unit type in advanced X-Wing and Swordfish patterns. | Avanzato |
Tecniche da padroneggiare a Esperto
- Tecnica X-Wing — Expert hyper grids give few digits away; fish patterns on candidates already pruned by the four windows are the intended path through the endgame.
- Swordfish technique — The windows shrink each digit's candidate field enough to make three-row Swordfish patterns genuinely findable — expert Windoku saves its last placements for them.
