Hur man spelar Renban Sudoku
Standard Sudoku-regler gäller. Varje lila linje måste innehålla en uppsättning på varandra följande siffror i valfri ordning. Linjens längd berättar exakt hur många på varandra följande nummer som behövs - T.ex. en 4-cellslinje kan innehålla 3,6,4,5.

Lila linjer maste innehalla konsekutiva siffror i valfri ordning

Vad är Renban Sudoku?

Renban Sudoku ritar lila linjer på rutnätet. Siffrorna på en lila linje måste utgöra en uppsättning på varandra följande heltal (som 3,4,5 eller 7,8), även om de kan förekomma i valfri ordning längs linjen. Linjens längd talar om exakt hur många på varandra följande tal som ingår. Detta skapar kraftfulla intervallbegränsningar: en 5-cells Renban-linje kan bara omfatta 5 på varandra följande värden från det möjliga intervallet 1–9.

Hur man löser Renban Sudoku

TeknikVad den görNivå
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. Avancerad
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. Avancerad
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). Avancerad
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. Avancerad

Vanliga frågor

Vad är Renban Sudoku?
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.
Kan siffror upprepas på en renban line?
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.
