temporarily down due to issues with blockchainI made a simple Bitcoin investing game with a friend:
http://www.bitmajority.comBasically, there are two teams, and people can send bitcoins to "invest" in either team and raise the team's score, with the game lasting 24 hours.
When the game ends, the team with the higher score wins and splits the total investment from both teams based, while the losing team gets nothing.
The winning investors get a share of the profit proportional to their score contributions.
A twist is that investing earlier gives you a higher score multiplier, a bigger share of the pot if you win, but is of course riskier.
The game is fully deterministic, and all transactions are recorded on the web site.
Fee is 2% for now. Transactions coming in after the game ends are returned minus 0.0005 fee.
Functionality for multiple overlapping games (4 24-hour games separated by 6 hours each) is done but I'll enable that if there is more interest.
If you guys have any suggestions or advice on how to improve the game, feel free to tell me.
Edit: blockchain.info is down, so I can't get any updates, will refund game if doesn't go back up soon
Edit2: all money for round has been refunded. 2 of the refunds were done manually.
