Tetris DS

[Edymion]

The ultimate puzzle game is back in bold fashion! You can now challenge friends over Nintendo's free WiFi Connect to determine just who has the fastest brain wink You control the blocks with both careful button presses and attention to touch-screen goodness!

Many different modes install a feel of novelty to this ageless game, and they introduce you to a whole new look and feel!

If you are going to do play it online it has a great 4 player mode. It takes most of the Mario Kart weapons and drops them into the game. The items can either destroy your foe or give you infinte long pieces. eek Then the thunderbolt is kill your foes, reason why is because they wont be able to turn there blocks. I have only played it a couple times only cause my wifi network in my house wont work with my ds. crying But if you get the chance to play it online, play 4 player first, the one on one play is kinda to plain for my tastes.
