The block size of argument is refers to the size of a 3x3 square area for a game that is 9x9 overall. The argument must be an object of { width: number, height: number }. The length of one side of the game (width multiplied by height) must be 3 or higher, and less than 9. If a larger size is specified, it will take longer to generate the game.
