크롭키 스도쿠 플레이 방법
표준 스도쿠 규칙이 적용됩니다. 두 인접 셀 사이의 검은 점: 한 숫자가 다른 숫자의 정확히 두 배입니다. 흰 점: 두 숫자는 연속됩니다(1 차이). 점 없음: 두 조건 모두 적용되지 않습니다.

흰색 점 = 연속된 숫자; 검은색 점 = 한 숫자가 다른 숫자의 두 배

크롭키 스도쿠이란 무엇인가요?

크롭키 스도쿠는 인접한 셀 쌍 사이에 점을 배치합니다. 흰 점은 두 숫자가 정확히 1만큼 다름을 의미합니다(연속). 검은 점은 한 숫자가 정확히 다른 숫자의 두 배임을 의미합니다(예: 2와 4, 또는 3과 6). 점이 나타나지 않는 경우, 두 조건 모두 적용되지 않습니다. 일부 크롭키 퍼즐은 '부정 제약'을 사용하여 점이 없으면 두 조건이 모두 성립하지 않음을 보장하여 더 많은 정보를 제공합니다.

기법기능레벨
White Dot Pairs White dots mark consecutive digit pairs: (1,2), (2,3), …, (8,9). Cross-reference with row and column constraints. 고급
Black Dot Pairs Black dots mark double-relationship pairs: (1,2), (2,4), (3,6), (4,8). Only these four combinations are valid. 고급
Negative Constraint No dot between two cells means they are neither consecutive nor in a 1:2 ratio — a powerful elimination on every unmarked adjacent pair. 고급
Dot Chain Analysis A sequence of connected dots forms a digit-value chain. Enumerate valid digit sequences for the entire chain simultaneously. 고급
1-2-4 and 2-4-8 Chains A black dot adjacent to a white dot often forces the common 1→2→4 or 2→4→8 chain. 고급

자주 묻는 질문

Kropki Sudoku란 무엇인가요?
Kropki Sudoku is a variant where dots appear between adjacent cells. A black dot means one of the two cells holds exactly double the value of the other. A white dot means the two cells hold consecutive digits (differing by 1). Standard Sudoku rules apply, and crucially: if there is no dot between two adjacent cells, they are guaranteed NOT to be consecutive and NOT to have a double relationship.
What does a black dot mean?
A black dot between two cells means one digit is exactly twice the other. For example: 1&2, 2&4, 3&6, 4&8. Note that 1&2 satisfies both black (1×2=2) and white (|2-1|=1) conditions — in Kropki Sudoku, a black dot is used when only the doubling relationship holds, not the consecutive one, unless specified otherwise.
What does a white dot mean?
A white dot between two cells means the digits differ by exactly 1: they are consecutive. Valid pairs are 1&2, 2&3, 3&4, 4&5, 5&6, 6&7, 7&8, 8&9. The order doesn't matter — either cell can hold the higher or lower digit.
How does the no-dot constraint work?
In standard Kropki Sudoku, every possible black dot and white dot relationship is marked. This means that if no dot appears between two adjacent cells, you can be certain those cells are neither consecutive nor in a 1:2 ratio. This negative information is just as powerful as the positive dot clues.
Is Kropki Sudoku harder than regular Sudoku?
Easy Kropki puzzles are accessible and make excellent teaching tools for the variant. Hard and expert puzzles are significantly more challenging than classic Sudoku because you must simultaneously track dot relationships and the negative no-dot constraint across every pair of adjacent cells.
How long does Kropki 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. Mastering the no-dot constraint is the key to faster solve times at all levels.
