Expert Klon Sudoku
Skuggade regioner är kloner — identiska i sifferinnehåll och position. En placering uppdaterar alla dess kloner samtidigt.
Expert Clone Sudoku. De svåraste pusslen på sidan — varje placering följer från precis korsklon och standardresonemang. Ingen gissning.

Lösningstekniker för Expert nivå
| Teknik | Beskrivning | Nivå |
|---|---|---|
| Clone Pair Deduction | Any digit placed in one clone region immediately forces the same digit in the corresponding cell of the other clone region. | Nybörjare |
| Constraint Propagation | A clone placement propagates through standard row, column, and box constraints in both regions simultaneously. | Medel |
| Clone-Box Interaction | If both clone regions share boxes with heavily constrained cells, the clone constraint rapidly resolves entire boxes. | Medel |
| Mirror Elimination | When a digit is eliminated from a position in one clone region by standard logic, it can be eliminated from the same position in the other clone region. | Avancerad |
| Multi-Clone Logic | With two clone regions, solving either provides equal information about both. Alternate deduction paths between clones for maximum efficiency. | Avancerad |
Tekniker att bemästra vid Expert
- X-Wing-teknik — Expert clone grids position the twins so fish eliminations in one region's rows force placements in the other — alternate fish scans with mirror updates until the loop closes.
- Swordfish technique — The clone constraint synchronises candidate patterns between distant bands, manufacturing the row-repetition a Swordfish needs — expert clones are built on this echo.

Relaterade varianter
Chaos Construction
Structure-as-puzzle taken to the limit: instead of mirroring known regions, you deduce where the regions even are.
Jigsaw Sudoku
Region-shape reading without the mirroring — nine snaking regions replace the standard boxes.
Diagonal Sudoku
Like clone cells, diagonal cells link distant parts of the grid — placements echo far beyond their own box.
