There are a total of 7 shapes in the Tetris classics game, named according to their shapes, namely long bar, T shape, square, L shape, reverse L shape, Z shape, and reverse Z shape.
The rules of the game are that players need to adjust and transform randomly falling blocks of different shapes and fill them into the appropriate positions. The filled rows will be automatically eliminated.
Players can eliminate 1 to 4 rows at a time, and as the total number of eliminated rows increases, the blocks will fall faster and faster.
Once a block is placed beyond the height of the original rectangle, the game ends automatically.
