Jak hrát Sudoku Konsekutivní
Bary mezi buňkami znamenají, že ty dvě číslice jsou konsekutivní
Pravidla
Standardní sudoku pravidla platí: naplňte každý řádek, sloupec a 3×3 box číslicami 1–9, každá objevující se přesně jednou.
Consecutive Sudoku označuje pruhy mezi páry sousedních buněk. Pruha znamená, že dvě číslice v těch buňkách se liší přesně o 1 — jsou po sobě jdoucí. Když se použije s negativním omezením (bez pruhy = nejsou po sobě jdoucí), to dává informaci o každém sousedním páru v celé mřížce, vytvářejíc mocnou síť omezení.

Časté otázky
Co je Consecutive Sudoku? ▾
Consecutive Sudoku is a variant where white bars appear between some adjacent cells. A white bar means those two cells hold digits that differ by exactly 1. Crucially, all consecutive adjacent pairs are marked — if there is no bar between two cells, they are guaranteed not to be consecutive.
How does the no-bar constraint work? ▾
Every adjacent pair that is NOT consecutive has no bar. This negative information is extremely powerful — it eliminates all consecutive digit pairs from unmarked cell boundaries. Experienced players apply no-bar eliminations as aggressively as the positive bar clues.
What pairs count as consecutive? ▾
Consecutive digits differ by exactly 1: 1&2, 2&3, 3&4, 4&5, 5&6, 6&7, 7&8, 8&9. The constraint applies to horizontally and vertically adjacent cells only — diagonal neighbours are not considered.
What is the best first move in Consecutive Sudoku? ▾
Look for long chains of consecutive bars — a chain of four bars forces four consecutive digits in those five cells. Also, digits 1 and 9 can only be consecutive with 2 and 8 respectively, so any cell surrounded by no-bar neighbours cannot hold 1 or 9 unless those specific partners are available nearby.
Is Consecutive Sudoku harder than regular Sudoku? ▾
At easy difficulty it is comparable to medium classic Sudoku. The bars and no-bars together provide a dense constraint web that makes early eliminations fast. Hard and expert puzzles become much more demanding as bar chains grow longer and interact with more rows, columns, and boxes.
How long does Consecutive Sudoku take to solve? ▾
Easy puzzles take 8–18 minutes. Medium puzzles run 18–35 minutes. Hard puzzles average 35–65 minutes and expert puzzles often exceed 90 minutes. Applying both bar and no-bar logic simultaneously is the key to efficient solving at all levels.
