High Society is an established auction game that already has a proven track record of success as a solid filler. It's a brilliant bidding game that offers a lot of tension and fun for the 20 minutes of time it takes to play. Both the Misfortune cards as well as the rule that the player with least money at the end is ineligible to win help create deliciously difficult choices. Being slightly more complex than For Sale, it's well-suited for gamers, but it can be enjoyed with non-gamers as well.
If you're look for a quick and tense filler with some meat on it, grab this edition while you can! While not as accessible as For Sale, it's arguably more tense and skilful, and provides agonizing but satisfying decisions and exciting game-play. This classic Knizia auction game is a super filler for gamers, and guaranteed to please.
