Big Top-Is it Clowntastic?

About Big Top, from BoardGameGeek:

Come one, come all to Big Top! Hire the wildest and most wonderful acts to attract crowds of delighted spectators. In this fast-paced auction game you'll bid on show-stopping acts to draw crowds to your circus, but beware - each winning bid will make your competition that much richer. But that's not all! Even the attractions you've already won will affect bids in future auctions. Each attraction card lists a number - bid that amount in any auction to place a coin on that card and gain the points! That means you don't need to win an auction - or even WANT to win it - to benefit from bidding! In this competitive world of circuses, you'll have to keep a close eye not just on your winnings, but on all of your opponents' bids. -description from publisher
