Како играти Ирегулар Дијагонал Судоку
Сваки ред, колона, обојена регија, и обе главне дијагонале (истакнуте у ћилибару) морају садржати сваку од 1–9 тачно једном. Регије замењују стандардне 3×3 блокове.

Шта је Ирегуларна Дијагонала Судоку?
Неправилни Дијагонални Судоку комбинује два варијантна типа: неправилне џигсо регионе из Џигсо Судокуа и дијагонална ограничения из Дијагоналног Судокуа. Обе главне дијагонале и сви неправилни региони морају садржати 1–9. Комбинација ствара високо ограничене загонетке с уникалном логиком решавања.

Како решити Ирегуларна Дијагонала Судоку
| Техника | Шта ради | Ниво |
|---|---|---|
| Map All 29 Units First | You have 9 rows + 9 columns + 9 irregular regions + 2 diagonals = 29 constraint units. Identify all irregular regions and both diagonals before starting. | Напредно |
| Diagonal–Region Intersection | Cells on a diagonal that also sit in the same irregular region create a powerful two-unit intersection — use both constraints simultaneously. | Напредно |
| Diagonal Pointing Pairs | If a digit on a diagonal is confined to one irregular region, eliminate it from all other cells of that region. | Напредно |
| Region Coloring for Diagonals | Trace which irregular regions each diagonal passes through. Regions with many diagonal cells are the most constrained. | Напредно |
| Chain Deduction Across Units | With 29 units, a forced digit in one unit often cascades through 3–4 other units. Track chains carefully to avoid errors. | Напредно |

Често постављана питања
Шта је Irregular Diagonal Sudoku?
Irregular Diagonal Sudoku combines two variants: irregular jigsaw-shaped regions replace the standard 3×3 boxes, and both main diagonals of the 9×9 grid must each contain 1–9 exactly once. Cells on a diagonal therefore belong to four groups: row, column, jigsaw region, and diagonal. It is one of the most constraint-dense variants available.
How many constraint groups does a diagonal cell belong to?
A cell on one of the main diagonals belongs to four groups simultaneously: its row, its column, its jigsaw region, and its diagonal. The centre cell belongs to five groups — both diagonals, plus row, column, and region. This extreme constraint density makes every placement very powerful.
Is Irregular Diagonal Sudoku the hardest variant?
It is among the most constrained variants. The combination of irregular regions and diagonal constraints means almost every cell interacts with an unusually large portion of the grid. Expert puzzles in this variant are among the most demanding logic puzzles on the site.
What order should I tackle the constraints?
Start with the diagonals, since diagonal cells carry the most constraints. Find hidden singles on each diagonal first. Then scan the jigsaw regions, keeping diagonal eliminations active. Update all four constraint groups — row, column, region, diagonal — after every single placement.
Can I use standard Sudoku techniques?
Yes — all standard techniques apply. You simply treat each diagonal as an additional house alongside the nine rows, nine columns, and nine jigsaw regions. The diagonal pointing pair (where a digit in a diagonal is confined to one row or column) is a particularly powerful technique unique to diagonal variants.
How long does Irregular Diagonal Sudoku take to solve?
Easy puzzles take 10–20 minutes. Medium puzzles run 20–40 minutes. Hard puzzles average 40–75 minutes and expert puzzles often exceed 90 minutes. The combined constraint density means that even easy puzzles require tracking four constraint groups simultaneously.
