English Auction

In English auctions, players take turns bidding in ascending order until no one outbids the last offer. This classic auction style appears in games like Power Grid, where careful resource management complements competitive bidding.
Open Auction

An open auction allows all players to bid publicly, raising the stakes until one emerges as the winner. This mechanic fosters player interaction and tension, as seen in Modern Art, where strategic bidding is crucial.
Dutch Auction

In Dutch auctions, the price starts high and decreases until a player accepts it. This creates a sense of urgency and reward for bold decisions, seen in games like Keyflower, where timing is key to securing valuable resources.
