Adventure Party: The Role-Playing Party Game

Adventure Party delivers a robust role-playing experience that can be enjoyed within 2 minutes of explanation. In this cooperative guessing game, 3-6 players take the roles of adventurers in a classic fantasy role-playing world, facing monsters and attempting heroic deeds.
Over the course of 3 Adventure scenarios, the party will work together and collectively attempt to score the most
Experience Points possible. Players will take turns, rolling their 20-sided die in secret. Based on how well or poorly they rolled, they will describe what their character does; first outlining their plans and then describing the outcome of their actions. The goal of which is to provide enough detail so that the GM for that turn can GUESS the number they rolled as closely as possible, earning the entire party Experience Points.
