The Wikipedia article does not support your view (I think they'd mention if it was a poker game
). You can't just make up rules on the spot to win arguments. This isn't Calvinball
Fake edit: in fact, here: http://www.heretical.com/pound/dollar.html
1. (As in any auction) the dollar bill goes to the highest bidder, who pays whatever the high bid was. Each new bid has to be higher than the current high bid, and the game ends when there is no new bid within a specified time limit.
2. (Unlike at Sotheby’s!) the second-highest bidder also has to pay the amount of his last bid – and gets nothing in return. You really don’t want to be the second-highest bidder.
(In case you didn't catch that- it's from an actual, published, book by someone who actually knows something)
