렌반 스도쿠 플레이 방법
표준 스도쿠 규칙이 적용됩니다. 각 보라색 선은 임의의 순서로 연속된 숫자 집합을 포함해야 합니다. 선의 길이는 정확히 몇 개의 연속 숫자가 필요한지 알려줍니다 - 예: 4셀 선은 3,6,4,5를 포함할 수 있습니다.

Purple lines must contain consecutive digits in any order
렌반 스도쿠이란 무엇인가요?
Renban Sudoku는 grid에 purple lines를 그립니다. 모든 purple line의 digits는 연속된 정수 세트(예: 3,4,5 또는 7,8)를 형성해야 하지만, line을 따라 어떤 순서로든 나타날 수 있습니다. line의 길이는 정확히 몇 개의 연속된 숫자가 포함되는지 알려줍니다. 이는 강력한 범위 제한을 만듭니다: 5-cell Renban line은 가능한 범위 1–9에서 오직 5개의 연속된 values만을 포함할 수 있습니다.

렌반 스도쿠 푸는 방법
| 기법 | 기능 | 레벨 |
|---|---|---|
| Length-Based Range | A Renban line of length L must contain L consecutive integers. The starting value is between 1 and 10−L, giving 10−L possible ranges. | 고급 |
| Shared Cell Intersection | If two Renban lines share a cell, that cell's value must fit both lines' consecutive ranges. Intersect the ranges to find valid values. | 고급 |
| Single-Range Reduction | When a Renban line's valid range reduces to a single starting value, all cell values are fully determined (in some order). | 고급 |
| Renban–Box Interaction | Digits on a Renban line within one box restrict the box's remaining cells. Use box uniqueness to narrow the line's range. | 고급 |

자주 묻는 질문
Renban Sudoku란 무엇인가요?
Renban Sudoku is a variant where purple lines are drawn across the grid. Every purple line must contain a set of consecutive digits (in any order along the line). For example, a 4-cell renban line might hold 3,4,5,6 or 6,4,5,3 — any arrangement, as long as the set forms a run of consecutive numbers. Standard Sudoku rules apply.
Do renban digits have to be in order?
No. The digits on a renban line must form a set of consecutive numbers, but they can appear in any order along the line. A 3-cell renban line holds three consecutive digits arranged in any sequence — it's the set that matters, not the sequence.
renban line에서 숫자가 반복될 수 있나요?
No. Because the digits must form a consecutive set and each digit in a set is unique, no digit can repeat on a renban line. This is an implicit constraint: a 4-cell renban line always contains exactly four distinct consecutive digits.
How do I start solving Renban Sudoku?
Start with the shortest lines and look for lines that share cells with highly constrained rows, columns, or boxes. A 2-cell renban line can only hold adjacent digit pairs (1&2, 2&3, ..., 8&9). Identifying which consecutive set fits each line, then cross-referencing with standard Sudoku constraints, is the core technique.
Is Renban Sudoku harder than regular Sudoku?
Easy and medium renban puzzles are comparable in difficulty to classic Sudoku at the same level. Hard and expert puzzles become significantly harder because you must track which consecutive sets are possible for multiple overlapping lines simultaneously, which requires combinatorial thinking on top of standard Sudoku logic.
How long does Renban Sudoku take to solve?
Easy puzzles take 8–18 minutes. Medium puzzles run 18–35 minutes. Hard puzzles average 35–60 minutes and expert puzzles can take over an hour. Solve time is most affected by the number and length of renban lines — more lines mean more interacting constraints.
