Sådan spiller du Samurai Sudoku
Fem overlappende 9x9 Sudoku-gitre. Hvert undergitter skal uafhængigt opfylde standard Sudoku-regler (1-9 i hver række, kolonne og boks). Hvor to undergitre deler en 3x3 hjørneboks, skal den boks opfylde begge gitre samtidigt. Løs undergitre med flest ledetråde først, brug derefter delte bokse til at låse op for andre.

Løsningsteknikker for Svær niveau
| Teknik | Beskrivelse | Niveau |
|---|---|---|
| Sub-Grid Independence | Each of the five 9×9 sub-grids satisfies standard Sudoku rules independently. Solve each one using all standard techniques. | Begynder |
| Overlap Box Exploitation | The four corner boxes where sub-grids meet are shared between two grids. Any digit placed in a shared box eliminates that digit from two sub-grids at once. | Mellemniveau |
| Cross-Grid Cascade | Completing a corner box in the central grid forces values in the corresponding corner grid's box, which may cascade further through that grid. | Mellemniveau |
| Shared Box Forcing | When a shared box is nearly complete, use both sub-grids' row and column constraints to force the remaining digits. | Avanceret |
| Global Number Counting | Across all five sub-grids, each digit 1–9 appears 5×9=45 times total. This global count can confirm placement decisions near the end. | Avanceret |

Teknikker at mestre på Svær
- Hidden Pairs technique — Cross-grid eliminations through shared boxes thin candidates in cells you weren't watching — periodically recount the boxes bordering each overlap, per grid, to catch hidden pairs.
- X-Wing-teknik — Fish stay inside a single 9×9 — never build an X-Wing from rows of two different sub-grids — but a fish elimination inside a shared box still exports to the neighbour grid.
