Turn Any Block Into Red Block
Tengen's version of the game Tetris is the best there is (except for the Atari Games coin-op), and with this little trick you could find your Tetris scores soaring!
The quickest way to big points is to score a "Tetris" - the elimination of four lines of blocks simultaneously. The only way to rack up a Tetris is to have plenty of bricks already on the screen and, if the computer is nice, a long red block will appear to neatly fit down a one block wide opening.
Now you can always be sure of getting a Tetris with this tip that changes an existing block into a long redbrick! When a block is falling, press 'Start' to pause the game, and then push Up, Up, Down, Down, Left, Right, Left, Right, 'B', and then 'A'. A long red block will replace the existing block at the top of the screen!
Level Select/Piece Removal
To initiate the level select in Tengen's excellent version of Tetris, you must first press 'Start' to pause the game, and then press Up, Down, Up, Down, Left, Right, 'B', 'B', and then press the 'A' button to choose any level of play up to seventeen!
We've all played Tetris and made a mistake that proved to be costly, and this second Tetris trick lets you correct your errors before they cost you the game.
First press 'Start' to pause play, and then press the pad Left, Down, Right, Up, Left, Down, Right, followed by 'B' and then 'A'. The piece will appear again at the top of the screen where it was before you goofed! There's only one catch - you can use this super trick only once per game!
