	// A unique bid auction is a type of strategy game related to traditional auctions where the
	// winner is usually the individual with the lowest unique bid, although less commonly the
	// auction rules may specify that the highest unique bid is the winner. Unique bid auctions
	// are often used as a form of competition and strategy game where bidders pay a fee to make
	// a bid, or may have to pay a subscription fee in order to be able to participate.
