One of the cool ones is an the Auction Fever game. When one player triggers the ‘Auction Bonus’, all players on that bank of games enter the bonus an bid against each other for the virtual items. As pointed out, the player is not able to change how much is won, but it does make for a spot of fun. (Here’s a bit of trivia you won’t read anywhere: The game was originally branded as eBay, but before the launch they decided that they didn’t want to be associated so closely with gambling.)

What always amazes me is that the fancy games rarely do as well as the simple ones. The ones that I find the most boring to work on, seem to do the best business over time. I guess when a person’s money is on the line, they tend to go with a game that they completely understand?
