I am going to a conference in a couple of weeks (hosting a stand) and we will have a couple of iPads and/or Galaxy Tab 2's (We have 3 iPads and 2 GTabs at our disposal).
Normally we run a game on a nintendo Wii (like Ten-pin bowling) for the delegates to have a go, and top score at the end of the conference wins something.

This year, we thought we would do iPad games, with the same thing, so that the delegates can get hands on with a tablet, and be in to win something. The delegates are all small/medium business owners, not necessarily tech savvy. I need a game that doesn't take too long to play, and will give a score to beat. Rugby Kicks is one thought we have had, but I am asking here for any others we can look at.

It must be:
* Relatively simple
* Quick (no more than 3 or so minutes)
* Have a score range that can produce a winner
* Look good.

What say you mighty Geeks?
