ハイパー数独の遊び方
標準の数独ルールが適用されます。緑色で網掛けされた4つの領域は追加のボックスです。それぞれにも1～9が含まれなければなりません。候補を排除する際は、標準の3×3ボックスとまったく同様に扱ってください。

4つの追加の網掛けされた3×3ボックスはそれぞれ1～9を含まなければならない
ハイパー／ウィンドウ数独とは？
ハイパー数独（ウィンドクとも呼ばれる）は、標準グリッドに4つの追加の影付き3×3領域を追加します。これらの領域は通常のボックスと重なり、標準のボックスと同様に、それぞれ1～9のすべての数字を含む必要があります。追加の制約により候補数が劇的に減少し、多くの場合、パズルは最初に見えるよりも簡単になります。

ハイパー／ウィンドウ数独 の解き方
| テクニック | それが何をするか | レベル |
|---|---|---|
| Region Overlap Analysis | Each Hyper region overlaps with two standard 3×3 boxes. Any digit placed in the standard box cells within a Hyper region also constrains the full Hyper region. | 上級 |
| Extended Naked Singles | With 13 regions total (9 standard boxes + 4 Hyper), naked singles appear far more often than in classic Sudoku. | 上級 |
| Pointing Pairs (Hyper) | If a digit in a Hyper region is locked to one row or column of that region, eliminate it from the rest of that row or column. | 上級 |
| Hyper–Box Interaction | A digit placed in a standard box cell that falls inside a Hyper region removes that digit from the entire Hyper region. | 上級 |
| X-Wing across Hyper | Hyper regions can serve as a fifth unit type in advanced X-Wing and Swordfish patterns. | 上級 |

よくある質問
Hyper Sudokuとは何ですか？
Hyper Sudoku (also called Windoku or Hyper-Sudoku) adds four shaded 3×3 regions to the standard 9×9 grid. Each shaded region, like a standard box, must contain the digits 1–9 exactly once. This gives a total of 13 uniqueness groups: 9 rows, 9 columns, 9 standard boxes, and 4 hyper regions — though many cells overlap between groups.
Where are the four hyper regions?
The four hyper regions are positioned symmetrically, offset from the standard boxes. They occupy the 3×3 areas starting at rows 2–4/columns 2–4, rows 2–4/columns 6–8, rows 6–8/columns 2–4, and rows 6–8/columns 6–8. Each hyper region overlaps with four standard boxes, creating a dense web of mutual constraints.
How do the hyper regions help solving?
Any cell inside a hyper region carries five constraints simultaneously: its row, column, standard box, and the hyper region. This extra constraint eliminates candidates faster than standard Sudoku. After every digit placement inside a hyper region, scan all five groups for new eliminations.
Is Hyper Sudoku harder than regular Sudoku?
Easy Hyper Sudoku is often easier than equivalent classic Sudoku because the extra constraints resolve the grid more quickly. Hard and expert Hyper puzzles are comparable in difficulty to their classic equivalents — the additional constraints help but also create complex multi-group interactions that require careful tracking.
What is the best first move in Hyper Sudoku?
Focus on cells inside hyper regions, especially those at the intersections of a hyper region and a standard box. These carry the most constraints and are the most likely to resolve immediately. Always scan all four hyper regions after every placement.
How long does Hyper Sudoku take to solve?
Easy puzzles take 5–12 minutes — often faster than classic Sudoku of equivalent difficulty. Medium puzzles run 12–25 minutes. Hard and expert puzzles take 25–60 minutes. The extra regions speed up early solving but hard puzzles compensate with fewer given digits.
