Како играти Клон Судоку
Стандардна правила Судокуа се примењују. Два истакнута подручја (Клон А у ћилибару, Клон Б у љубичастој) морају садржати идентичне распореде цифара — одговарајуће ћелије морају имати исту цифру. Постављање цифре у једном клону аутоматски ограничава исту позицију у другом клону.

Marked regions must contain identical digit arrangements
Шта је Клон Судоку?
Clone Sudoku означава парове regions (clones) на grid. Сваки пар clone regions мора садржати тачно исти аранжман digits — ако један clone има 3 у својој top-left cell, други clone мора такође имати 3 у својој corresponding cell. Clone constraints стварају моћне symmetry-based deductions које могу решити целе regions одједном.

Како решити Клон Судоку
| Техника | Шта ради | Ниво |
|---|---|---|
| Clone Pair Deduction | Any digit placed in one clone region immediately forces the same digit in the corresponding cell of the other clone region. | Напредно |
| Constraint Propagation | A clone placement propagates through standard row, column, and box constraints in both regions simultaneously. | Напредно |
| Clone-Box Interaction | If both clone regions share boxes with heavily constrained cells, the clone constraint rapidly resolves entire boxes. | Напредно |
| Mirror Elimination | When a digit is eliminated from a position in one clone region by standard logic, it can be eliminated from the same position in the other clone region. | Напредно |
| Multi-Clone Logic | With two clone regions, solving either provides equal information about both. Alternate deduction paths between clones for maximum efficiency. | Напредно |

Често постављана питања
Шта је Clone Sudoku?
Clone Sudoku is a variant where two highlighted regions of the same shape appear on the grid. The two regions are 'clones' — they must contain exactly the same digit arrangement. Every cell in one region holds the same digit as the corresponding cell in the other region. Standard Sudoku rules apply.
How do the clone regions correspond?
The two clone regions are the same shape and size. Each cell in one region is paired with the corresponding positionally-equivalent cell in the other region. Placing a digit in any cell of one clone immediately fixes that digit in the matching cell of the other clone.
Can clone regions overlap with the same rows or columns?
Yes. The puzzle constructor ensures that the clone constraint is always consistent with Sudoku rules — the two regions are positioned so that corresponding cells are in different rows, columns, and boxes, allowing the same digit to appear in both without violating uniqueness.
Is Clone Sudoku harder than regular Sudoku?
The clone constraint effectively halves the number of independent cells to solve — every deduction in one region automatically applies to the other. Easy Clone puzzles resolve noticeably faster than classic Sudoku. Hard and expert puzzles use the clones to create complex bi-directional constraint chains.
What is the best strategy for Clone Sudoku?
Treat the two clone regions as a single constraint. Whenever you eliminate a candidate from a cell in one region, immediately eliminate it from the corresponding cell in the other. Focus on the rows, columns, and boxes that interact with both regions simultaneously.
How long does Clone Sudoku take to solve?
Easy puzzles take 6–15 minutes. Medium puzzles run 15–30 minutes. Hard puzzles average 30–60 minutes and expert puzzles can take 60–90 minutes. The bilateral nature of the clone constraint makes mid-game breakthroughs especially satisfying.
