The first piece will start falling as soon as you click Start. You can move the piece back and forth with the left and right arrow keys. Pieces will also be rotated each time you press the up arrow key. When you're happy with the position and rotation of a piece, you can quickly send it to the bottom of the screen with the down arrow key.
Your goal throughout the game is to create even rows. Doing so will eliminate the row and increase your score. It will also keep the pieces from filling up the screen and bringing your game to an end.
One cool feature of this game is the ability to toggle between songs. You can switch between three songs using the bar on the right side of the screen.
