Your goal is to control falling shapes made up of four blocks. You need to rotate them and move them from side to side in order to create unbroken horizontal lines. As soon as you make a line, it vanishes and you earn points. The objective is to achieve the highest score before the blocks reach the top of the screen, which will end the game.
How to play
Move the piece across the playing field by using the left and right arrow keys. To make the piece fall faster, press the down arrow key. The up arrow key is used for rotating the current shape. Most shapes can be rotated clockwise, which may help them fit into available spaces better. Press Enter to immediately return the current piece to the very bottom of the playing field.
