Tentris

This is a Tetris clone. You will get 100 points for every full line that gets removed. You will also get points for every new stone from 1 to 5. The game speed increases every level till level 10. The game ends when no new stone can put at the top of the play field because there is no space left. The up-arrow key rotates the stones and the left- and right-arrow keys move the stones left and right. The down-arrow key let move the stone down faster.
