A puzzle game where seven different types of blocks continuously fall from above and you must arrange them to make horizontal rows of bricks. Completing any row causes those blocks to disappear and the rest above move downwards (completing four rows at once is called a Tetris). The blocks above gradually fall faster and the game is over when the screen fills up and blocks can no longer fall from the top.
You must arrange bricks to form rows without the ‘wall’ getting too high, or it’s game over. You can rotate bricks so that they fit into the wall and once a row is complete it will disappear, thus lowering the wall. Eliminated rows will lower the number of lines you need to complete a level. Bricks fall faster in the higher levels and sometimes there are already bricks in the field that block your path. Often, when you try to make a Tetris (four rows of lines that are removed at once), you end up waiting a long time for the long red brick (the only way of completing a Tetris). It is interesting to note that every brick is made up of exactly four blocks.
