안티 연속 스도쿠 플레이 방법
표준 스도쿠 규칙이 적용됩니다. 추가 규칙: 직교로 인접한 셀(모서리 공유)은 연속된 숫자를 포함할 수 없습니다. 셀이 5를 보유하면 네 이웃 모두 4와 6을 피해야 합니다.

안티-연속 스도쿠이란 무엇인가요?
안티 연속 스도쿠(Non-Consecutive 스도쿠의 더 엄격한 형태)는 직교적으로 인접한 두 셀이 연속된 정수를 포함할 수 없다는 규칙을 부과합니다. 이 변형은 제약 조건만으로도 많은 candidate 쌍을 제거하기 때문에 종종 더 적은 주어진 숫자가 필요합니다. 때로는 Anti-King 또는 Anti-Knight와 결합하여 극도로 제약된 퍼즐을 만듭니다.

| 기법 | 기능 | 레벨 |
|---|---|---|
| Global Candidate Pruning | For every filled cell, remove its ±1 neighbours from all orthogonally adjacent cells immediately. | 고급 |
| Digit 5 is Most Constrained | 5 cannot be adjacent to 4 or 6. Use this to restrict placement of 5 across the entire grid. | 고급 |
| Chain Propagation | Placing a digit propagates constraints along rows and columns, often triggering a cascade of forced placements. | 고급 |
| Forbidden Pair Maps | Build a map of forbidden digit pairs for each adjacent pair of cells and use it to eliminate candidates systematically. | 고급 |

자주 묻는 질문
Anti-Consecutive Sudoku란 무엇인가요?
Anti-Consecutive Sudoku is a variant where no two orthogonally adjacent cells (horizontally or vertically neighbouring) may contain consecutive digits. The rule applies everywhere on the grid without any markers. Standard Sudoku rules also apply throughout.
How is Anti-Consecutive different from Non-Consecutive Sudoku?
Anti-Consecutive and Non-Consecutive Sudoku are the same constraint — the name is used interchangeably by different puzzle communities. Both mean: no two horizontally or vertically neighbouring cells may hold digits that differ by exactly 1.
Which digit placements trigger the most eliminations?
Digits in the middle of the range (4, 5, 6) eliminate two consecutive neighbours simultaneously. Placing a 5 removes both 4 and 6 from all four orthogonal neighbours, and placing those 4s and 6s in turn removes 3 and 7 from their neighbours — creating a cascade effect. Starting with central digits often unlocks large portions of the grid.
Is Anti-Consecutive Sudoku accessible for beginners?
What is the best approach to Anti-Consecutive Sudoku?
Treat the anti-consecutive constraint as an additional elimination layer. After every digit placement, immediately update all four orthogonal neighbours to remove ±1 from their candidate lists. The more given digits you have to start with, the more these cascade eliminations interact.
How long does Anti-Consecutive Sudoku take to solve?
Easy puzzles take 5–15 minutes. Medium puzzles run 15–30 minutes. Hard puzzles average 30–55 minutes and expert puzzles can take 60–90 minutes. Expert puzzles with very few given digits rely entirely on the anti-consecutive constraint for deductions.
