It is a classic made modern AND it's good to go!
First is Push mode. Push is sort of like standard Tetris, but you play it against another person. Your goal is to clear lines of 2 or more to 'push' your opponent to the end of a red line. The first person to do it, wins.
Next is Touch mode. You use your stylus to move tetriminoes left or right. In the normal mode, you must clear tetriminoes until a cage of balloons reaches the ground. In puzzle touch mode, you clear objectives on pre-made levels.
Puzzle mode is where you must choose the right shape to go into the 'missing space'. If you make the wrong move, you must start all over. In some ways, this is sort of east because yo uwill evntually get the right combination.
Standard, is the original Tetris, but you can choose to play with or without items. The items are: star, lightning, red shell, banana, boo, and mushroom. Mushroom makes a random opponent's blocks fall faster for a short period of time. The star makes you invulnerable to other items and gives you only 'I' tetriminoes for a sort period of time. The Banana randomly scrambles an opponent's placed tetriminoes. The Boo covers an opponent's 'next' blocks, lowering strategic maneuvers. The red shell clears the bottom 2 rows of your already placed tetriminoes. The lighting paralyzes your blocks so that you can't move them!
In mission mode, you also have to clear objectives in a certain amount of time. If you don't clear it fast enouh, you will lose hearts.
Finally, there is catch mode. Probably the the most 'different' form of Tetris, thismode has you catching tetriminoes as they fall. You objective is to make a 4 by 4 square and then detonate it by pressing the 'X' button. Metroids fall down also, kill them to score big points.
Overall a great game to have and enjoy. With 10-player single-card multiplayer and Nintendo Wi-Fi connection, this game is a must have for multiplayer fans.
