A PUZ file consists of a header section followed by a data section. The header section contains information about the puzzle, such as its name, author, copyright information, and grid dimensions. The data section contains the puzzle’s grid, which consists of cells that can be either filled with letters or left blank. Each cell in the grid is represented by a single byte, and the value of the byte indicates the type of cell. A value of 0 represents an empty cell, while a value greater than 0 represents a filled cell. The value of a filled cell indicates the letter that occupies that cell.
