Како играти Палиндром Судоку
Стандардна Sudoku правила важе. Свака сива линија је палиндром - Низ цифре се чита исто с оба краја. За линију од 5 ћелија која чита 3,7,5,7,3, позиција 1 = позиција 5 и позиција 2 = позиција 4.

Шта је Палиндром судоку?

Палиндром Судоку означава линије на мрежи чији низ цифара мора бити палиндром — читање исто у оба смера. Ако линија има ћелије A-B-C-D-E, тада A=E и B=D, док C је централна цифра. Ово ствара парове ћелија које морају делити исту вредност, делујући као моћна ограничења једнакости преко мреже.

Mirror Pair Identification In a palindrome of length L, cell i and cell L+1−i must share the same digit. Identify all mirror pairs before solving. Напредно
Centre Cell Freedom The central cell of an odd-length palindrome has no mirror constraint — it is only restricted by standard row/column/box rules. Напредно
Mirror Propagation Once one cell of a mirror pair is determined, immediately set its partner to the same value. Напредно
Multi-Palindrome Intersection If two palindromes share a cell, that cell must satisfy both palindrome relationships simultaneously. Напредно

Често постављана питања

Шта је Palindrome Sudoku?
Palindrome Sudoku is a variant where grey lines are drawn across the grid. Every grey line must read the same forwards and backwards — meaning the first cell mirrors the last, the second mirrors the second-to-last, and so on. Standard Sudoku rules apply throughout.
How does the palindrome constraint work?
For any palindrome line, cell positions are mirrored around the centre. On a 6-cell line, cells 1 and 6 hold the same digit, cells 2 and 5 hold the same digit, and cells 3 and 4 hold the same digit. This immediately links distant parts of the grid — placing a digit at one end fixes the digit at the other end.
Can palindrome lines have repeated digits?
Yes, palindrome lines inherently require digit repetition — each mirrored pair shares the same digit. However, standard Sudoku rules still apply, so a repeated digit must be in different rows, columns, and boxes. Palindrome lines are carefully constructed so that this repetition is always consistent with uniqueness rules.
Is Palindrome Sudoku harder than regular Sudoku?
Easy palindrome puzzles are often easier than classic Sudoku because the mirroring immediately links cells across the board, providing extra deductions. Harder difficulties become quite challenging because you must track mirrored constraints across long lines while maintaining standard Sudoku logic.
What is the best first move in Palindrome Sudoku?
Find palindrome lines where one endpoint cell is already constrained by its row, column, or box. Placing a digit there immediately fixes the mirrored cell at the other end. Also look for odd-length lines — the centre cell has no mirror partner, so it's only constrained by standard Sudoku rules.
How long does Palindrome Sudoku take to solve?
Easy puzzles take 8–15 minutes. Medium puzzles run 15–30 minutes. Hard puzzles average 30–60 minutes and expert puzzles often exceed 90 minutes. The difficulty increases sharply when multiple long palindrome lines overlap across the same region of the grid.
