The Graphics of the game re-create what all tetris games looked like. The Shapes seem to look the same, but of course higher quality since this is a 3DS, not an older device capable of Tetris.
Sound tracks I have found so far seem to be identical to Tetris Party LIVE for DSiWare. I cannot say much in this category. The sound quality depends if you are using the 3DS speakers, or headphones. You should notice a difference there.
I have counted 18 different Game Modes. Each Unique in their own way.
Traditional Marathon, you know...
Ten Computers will challaege you to battle in tetris one by one.
Play in a narrow Matrix to clear as many lines as you can in 60 seconds. Coins can be exchanged for items to help you clear lines.
Play in a narrow Matrix to clear as many lines as possible as incoming lines slowly make their way to the top.
Use tetris pieces to finish a jigsaw puzzle.
Place tetris pieces into the backround's shadow to complete the picture.
Shoot tetris pieces into holes in the plane of the same shape to clear them.
Stack tetris pieces on a Cylindrical Matrix to guide a white climber to the top of the Matrix
Clear lines with bomb pieces in tetris pieces to destroy blocks.
Stage Racer Plus
Race through a course using tetris pieces.
Cover stars on the Matrix with tetris pieces from the "front" and "back" to obtain them.
Tetris pieces fall at their fastest from the start.
Clear 40 lines as fast as possible
Augmented Reality Marathon. That sounded repetitive.
Augmented Reality Tower Climber. Repetitive once again.
I find this game very convenient to just kill time. With so many different modes to play.
Replay Value: Very High
