Scoop: Friends Prediction League

Scoop is a zero-real-money friends prediction league for adults. Friends can host a private league, make predictions on sports, pop culture, or personal challenges, and stake virtual 'Scoops' (bragging points). If a call is lost, a silly photo-proof forfeit is owed, which the league votes to verify.

The Casebook: Monthly Co-op Detective Mystery

The Casebook is a monthly co-op detective mystery game designed for couples. It is an asymmetric two-player game where one partner works with the Evidence Board (crime-scene photos, documents, a timeline) and the other works with the Witness Files (interview transcripts). Neither partner can solve the case alone; the game encourages conversation and sharing information unique to each role.
