Game Rules:
Hitori is a unique puzzle game where the goal is to eliminate adjacent repeated numbers. In each board, you need to follow these three rules:
Uniqueness Rule: No row or column can contain the same number. In other words, identical numbers cannot be adjacent in each row or column.
Black Block Rule: Some cells are initially marked as black blocks. Numbers in black blocks cannot be adjacent.
Isolation Rule: There should not be two adjacent white blocks. No white block can be surrounded by other white blocks, forming an isolated area.
