Friendly prediction markets to turn trips into a running tournament

On a trip with my friend, he introduced me to Kalshi and Polymarket and was shocked at how degenerate it was being able to bet on literally anything. So naturally I built an app ironically where we could do the same thing (with fake money) on group outings!

Managed to get a prototype finished in time for our big 14-person annual ski trip and we had a blast 'betting' on things like "Will [friend that always breaks his phone] break his phone?" and "Who will win the first game of Jackbox?" Having a low-stakes running leaderboard during our trip was so fun that I decided to flesh it out and share it with others for their trips, wacky professors, etc.

*How It Works*

1. Create a group for your trip and give your friends the group code to join.

2. Everyone starts with the same amount of Tokens/Points/Ski-bux that they can wager on each question.

3. Place bets on the options that you think will win - the more bets on an option, the more it costs to pick that option.

4. Anyone can propose when an outcome has happened and everyone gets 24 hours to dispute it.

5. Every share of the winning option pays out as 1 Token once the 24 hours has passed. So if you bet 2 tokens when the odds were 50%, you win 4 Tokens!

Please let me know what you think and what features I should add to make it even more fun for your friend groups!
