Tetra

Tetra is a puzzle game using tetrominoes. A tetromino is a grouping of four blocks, of which there are only 7 distinct combinations. These tetrominos are thrown into the top of a 10×20 grid one at a time and fall to the bottom of the play area. The purpose of the game is to line up 10 in a row, which makes the row disappear. You get more points per row if you eliminate multiple rows at a time. You also get points for landing a tetromino. For every 10 lines you clear you go to the next level where the tetrominoes fall faster and are worth more points. Try to get as many lines and the highest score that you can.
