In this game, you will play the classic Tetris game with different levels. A group of 4 blocks will drop from the top of the screen; you can move the blocks and rotate them until they drop to the bottom of the screen, and then the next group of 4 blocks appears. You should arrange the blocks so that the blocks fill up a complete row, and then the row of blocks will be destroyed. After destroying a certain number of rows, you can advance to the next level. If the pile of blocks reaches the top of the screen, then you lose. As the game progresses, the speed of the dropping blocks will increase, making the game more and more difficult. Control the blocks so that complete rows are filled. Use the left and right arrow keys to move, up arrow key or x to rotate clockwise, z key to rotate anti-clockwise, and the down arrow key to drop.
