Welcome to the Roaring 20s, when you will try to attract the trendiest dinos to your glamorous party.

Each round, you bid on a dino or pass. As every dino has different preferences, you need either the right snacks to lure it or splendid gems to bribe it. If you want to jump out of the bidding, place your "Mine!" card on one of the bid cards available; the earlier you pass, the more choices you have. Whoever sticks in the bidding long enough wins the dino, then they decide whether to pay with snacks or gems, with no change if you overpay.

Your goal is to have the most points at game's end. Each dino is worth 1-5 points on its own, with pairs and triplets being worth 3 and 6 points. That said, you can choose to discard an acquired dino if it's a duplicate in order to transform your "Mine!" card into a joker. Why would you want to do that? Because sequences of dinos are also worth points, with six in a row being worth 15 points, for example.

If you make clever bids, occasionally pass at the right moment, and get the most valuable guests, you’ll be crowned the ultimate prehistoric party animal!
