Circo almost lost an eye putting a touch screen into my bartop. He sort of looked like this:

I keep telling him to post the pictures, or make a thread based on cabinet injuries. He ended up getting safety goggles for X-mas.
Back to the topic. I found that the touch screen adds a lot to my machine. For the first time there are games that my wife will actually play. The touch screen also gives some games an extra kick. The great thing about a touch screen, you can add games to your cabinet that would not be put on a regular cabinet. I actually like my bartop better than my fullsize.
Here is a partial list of some fun games. The best thing, you can demo these from the Reflexive site to see if you like them.
The address is:
http://www.reflexive.com/These are matching type games:
Bejeweled 2
Chuzzle
Madcaps
Chainz
Combo Chaos
Balloon Blast
Casino Games and Card Games
These are my favorite type, they play like you're at a casino, but you do need a keyboard on some to enter how much you want to spend at the beginning.
Video slots- (Real Deal made by Phantom- or Slots from Bally Gaming)
Video poker-
Video Blackjack- I play either Real Deal Casino, or Casino Island.
Solitaire- These games are just more fun when using a touch screen.
Trivia type games:
Trivia Machine- found on the Reflexive sight.
Trivia Net Challenge- Haven't tried it yet, but it seems like it would work.
Trivial Pursuit- Haven't tried these yet either.
You Don't Know Jack- I haven't tried this one on the machine yet, but Circo is coming over Friday and we'll give it a tryout.
Word, matching, and Misc. type games:
Spin and win
Slingo
Puzzle Word
Mirror Magic- I like this one. You have two pictures that look identical. You must find 5 or 6 things that are different. You just touch the different items.
Flip Words
Mahjong games- Like solitaire, these games get a little kick when playing. Not everybody likes tile matching games. Super Mahjong and Mahjong towers are fun.
Anyways, this is a start. My next project is going to add a touch screen jukebox to it. I'm not an audiophile, but I do think it will be a great feature.
