Imposter!: The After-Dinner Mystery Game is a board game released in 2019 for 3–16 players, 30 minutes per game, and ages 8 and up. Its main mechanics are Simultaneous Action Selection, Memory, and Team-Based Game.
Imposter is a lively after-dinner game in which players use debate, bluff and logic to win points. A Murder Mystery-style deduction game: Imposter! is a conversation-based mystery game of social deduction and bluffing. All of you are guests at the Earl of Simpleton’s country estate, but some of you are trying to make off with his treasures undetected. Each round, a selected postmaster will choose some guests to send things out of the castle in the Royal Mail bag. The bag’s contents are revealed at the end of the round, and Imposters score a point if any treasure has made its way into it. Now it’s time to figure out which of those chosen players put that treasure in there. Are they looking a bit shifty? Are they a bit quick to pass the blame to others? You have your suspicions, but let’s see how they behave in the following rounds…The first team to five round victories wins the game, but the Innocents will win if they can unmask the Imposters before that point! —description from the publisher's website
