This is a simple block-sliding game.
The rules are only three:
1. Move all the blocks on the board by sliding them up, down, left, or right within an 8x8 grid.
2. After a block is moved, the next block will be generated in a random empty space. The game ends if there is no space to generate a new block.
3. Filling an entire row or column will eliminate the blocks. Eight or more adjacent blocks of the same color will also be eliminated.
