Here you can play Tetris which is one of the most popular puzzle games of all time. The game was originally developed by Alexey Pajitnov and released in 1984 and is available on nearly every gaming platform available. The object of tetris is to make horizontal rows out of the various different shapes as they fall. Upon creating a row it will disappear, and as you progress though the levels, the shapes start to fall faster and faster. The game play is so simple, yet very addictive since it becomes very challenging as the shapes start to stack up and you feel the pressure of running out of room. Should the shapes stack up to the top as a result of you failing to clear a rows faster than they are falling, the game will be over for you.
