Sådan spiller du Sukaku
Hver celle starter med et sæt kandidatcifre vist som blyantsmarkeringer. Tryk på et tal for at fjerne den kandidat fra den valgte celle. Når kun én kandidat er tilbage, placeres cifferet automatisk. Celler der viser et enkelt stort ciffer er faste og kan ikke ændres. Standard Sudoku række-, kolonne- og boksregler gælder.

En blyantsmarkerings-stil variant, hvor ledetråde er givet som kandidatsæt
Hvad er Sukaku?
Sukaku (数角) er en Sudoku-variant, hvor i stedet for givne digits, får hver celle et sæt mulige candidates. Løseren skal eliminere candidates ved hjælp af standard Sudoku-logik, indtil hver celle har præcis én tilbageværende candidate. Nogle Sukaku-puzzles giver meget sparsomme candidate sets (næsten komplette givens), mens andre giver fulde eller næsten fulde candidate lists, hvilket kræver avancerede techniques for at løse.

Sådan løser du Sukaku
| Teknik | Hvad det gør | Niveau |
|---|---|---|
| Candidate Scanning | Start by scanning rows, columns, and boxes — any candidate appearing in only one cell in a group must be placed there. | Avanceret |
| Cross-Hatch Elimination | When a digit is placed (or reduced to one candidate), eliminate it from all cells in the same row, column, and box. | Avanceret |
| Nøgne enere | A cell with only one remaining candidate is a naked single — the digit is forced. In Sukaku, this happens automatically when you eliminate down to one candidate. | Avanceret |
| Skjulte enkeltcifre | A candidate that appears exactly once in a row, column, or box must be placed in that cell regardless of how many other candidates that cell shows. | Avanceret |
| Pair Elimination | Two cells in a group that share only the same two candidates form a naked pair — both candidates can be eliminated from all other cells in that group. | Avanceret |

Ofte stillede spørgsmål
What is Sukaku?
Sukaku is a Sudoku variant where every cell in the 9×9 grid starts pre-filled with a set of pencilmark candidates instead of given digits. Your task is to eliminate incorrect candidates using standard Sudoku rules until exactly one digit remains in each cell. All 81 cells begin with multiple possibilities.
Hvordan adskiller Sukaku sig fra almindelig Sudoku?
In classic Sudoku, some cells are pre-filled with confirmed digits. In Sukaku, no cell has a confirmed digit — instead, each cell shows a subset of possible digits as pencilmarks. The starting pencilmarks are curated by the puzzle constructor and are always consistent with the unique solution.
Are the starting pencilmarks always correct?
Yes. The pencilmarks shown at the start of a Sukaku puzzle represent a valid subset of candidates for each cell — they are never wrong, but they may include more candidates than strictly necessary. Your job is to eliminate all but the correct digit using logical deductions.
What techniques work best in Sukaku?
All standard Sudoku elimination techniques apply: naked singles (when only one candidate remains in a cell), hidden singles (when a digit can only go in one cell within a row, column, or box), naked pairs, pointing pairs, and advanced techniques like X-Wings and Swordfish. The absence of given digits means you rely entirely on elimination.
Is Sukaku harder than regular Sudoku?
Easy Sukaku is more forgiving than classic Sudoku because the pencilmarks are already provided — you never have to work out candidates from scratch. Hard and expert Sukaku puzzles with minimal starting candidates require the same advanced techniques as difficult classic Sudoku.
How long does Sukaku take to solve?
Easy puzzles take 5–15 minutes. Medium puzzles run 15–30 minutes. Hard puzzles average 30–60 minutes and expert puzzles can take over 90 minutes. Solve time scales with how many eliminations each technique step provides.
