Hvordan spille Cube/3D Sudoku
To 9×9 Sudoku-ristre overlapper i en felles 3×3 hjørneboks. Ristre A (blå fargetone) dekker radene 1–9, kolonnene 1–9. Ristre B (grønn fargetone) dekker radene 7–15, kolonnene 7–15. Den felles boksen (radene 7–9, kolonnene 7–9) tilfredsstiller begge ristrene. Hvert ristre må uavhengig oppfylle standard Sudoku-regler.

Løsningsteknikker for Vanskelig-nivå
| Teknikk | Beskrivelse | Nivå |
|---|---|---|
| Shared Box Exploitation | The overlapping 3×3 box satisfies both grids. Digits placed here eliminate from rows and columns in both Grid A and Grid B simultaneously. | Nybegynner |
| Grid A/B Isolation | Outside the shared box, each grid operates independently. Apply standard 9×9 Sudoku logic to each grid in turn. | Middels |
| Cross-Grid Cascade | Completing the shared box often cascades through the adjacent rows and columns of both grids, rapidly resolving nearby cells. | Middels |
| Overlap Constraint | The shared box must satisfy: Grid A's bottom-right box rules, AND Grid B's top-left box rules, AND both grids' overlapping row/column constraints. | Avansert |
| Twin Digit Counting | Each digit appears 9 times in Grid A and 9 times in Grid B, but only once in the shared box. This counting helps verify near-complete grids. | Avansert |

Teknikker å mestre på Vanskelig
- Hidden Pairs technique — Cross-grid traffic through the overlap silently prunes the boxes adjacent to it — recount those eight boxes (four per grid) regularly; hard cube grids hide pairs exactly there.
- X-Wing-teknikk — Build fish strictly within one grid — rows of grid A and grid B never combine — but prioritise X-Wings whose eliminations touch the shared box, since those feed both grids.
