JUDGI is a social party game for the over-18 crowd that fosters hilarious conversation and debate by providing snarky award prompts based on the presentation of the holiday cards you received and their respective senders. More about the game below: -Only one person per group needs the app to play, and it’s perfect for any holiday gathering, whether it’s a small group of friends having a fun night in, or a big family coming together for the yearly gift exchange. -You can play with just the cards you received, but JUDGI is best enjoyed with a combination that includes cards from people you don’t know (judging a book by its cover is encouraged here). -The first six prompts are free, but the full access to all the prompts is available for a one-time purchase of $2.99.
