It's really simple, right now bitcoin is trading at $91

If the auction is for one bitcoin http://www.dreamybids.com/action.php?id=374

for the auction to start we need at least 5 players seated in the auction.. each player needs to have $18 in bids (37 bids) in their account.

$18 x 5 =$91 the cost of the bitcoin

Only 1 person will win the auction, so the auction winner gets 1 bitcoin for the $20 they used to buy bids.

What's really cool is you can win the $20 in bids you need in the arcade. So you never have to spend money.

Set the high score then earn bids each time another player fails to beat your high score.

Take the piles of bids you won in the arcade to go win you some bitcoins.

You get 2 free bids when you sign up.
