Best single device multiplayer iPad games?

[Primoz]

Worms and Tank trouble.

For me, the best of the best is Greedy Bankers vs.
Then of course Marble Mixer, Fruit Ninja HD, That's My Fish, and Carcassonne.

A hidden gem that is actually a forgotten classic is ORBITAL, you are your own worst enemy in this game so crappy ai won't ruin the enjoyment. They have a lite version for Iphone. Unfortunately it isn't universal but it is available in HD for ipad. (http://itunes.apple.com/app/orbital-hd/id364600320?mt=8)

Another game that me and the wife have enjoyed is KING OF OPERA (http://itunes.apple.com/app/king-of-opera/id408697793?mt=8).

Agreeing with Ice Rage. That game is deceptively simple. Scoring goals is a huge cause for celebration, heh.

iAvoid! This is a really good 2 player on one device game!

Tap tap Revenge with different songs, i think the best game for me.
