비연속 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.

논-연속 스도쿠이란 무엇인가요?
Non-Consecutive Sudoku는 전역 제약 조건을 부과합니다: 모서리를 공유하는 두 cell (직교적으로 인접)은 연속된 digit을 포함할 수 없습니다. 따라서 cell이 5를 포함하면, 모든 이웃은 4와 6을 피해야 합니다. 이 단일 규칙은 candidate 배치를 극적으로 제한하고, 여전히 유일하게 풀 수 있는 puzzle을 생성하면서 standard givens count를 줄일 수 있습니다.

|---|---|---|
| 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
Non-Consecutive Sudoku란 무엇인가요?
Non-Consecutive Sudoku is a variant where no two horizontally or vertically adjacent cells may contain consecutive digits. There are no markers on the grid — the non-consecutive rule applies globally to every pair of neighbours. Standard Sudoku rules also apply.
How does the global non-consecutive rule constrain the grid?
Every pair of adjacent cells cannot differ by exactly 1. This means you cannot place a 4 next to a 3 or a 5. For every digit you place, you must eliminate that digit ±1 from all orthogonal neighbours. This propagates eliminations across the entire board immediately after every placement.
Which digits are most affected by the non-consecutive rule?
Digits 1 and 9 can only be invalid next to 2 and 8 respectively — so they are least affected. Digit 5 cannot be adjacent to either 4 or 6, which is a moderate restriction. Digits 4, 5, and 6 are most affected because they are adjacent to two common digit pairs simultaneously.
Non-Consecutive Sudoku가 regular Sudoku보다 harder한가요?
Yes, typically. The global constraint eliminates many more candidates than standard rules alone. Easy puzzles are accessible and resolve quickly. Hard and expert puzzles compensate with fewer given digits, making the non-consecutive constraint the primary source of all deductions.
What is the best first strategy for Non-Consecutive Sudoku?
After placing each digit, immediately mark all orthogonal neighbours as unable to hold ±1. Scan rows and columns for digits that can now only go in one cell due to these combined eliminations. Digit 5 is particularly useful as a placement anchor — wherever 5 is placed, both 4 and 6 are eliminated from all four neighbours.
How long does Non-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. Non-Consecutive Sudoku rewards players who apply the constraint globally and systematically after every move.
