I've decided to make a spreadsheet game called the 50/50 game. It's called the 50/50 game simply because both opponents have a 50% chance to win, it requires no skill at all and purely luck based.
Example of how it works
Player 1 is the round starter. He PMs me or posts on this thread and I'll give him/her a deposit address. After I get the deposit, I'll update the spreadsheet so anybody can challenge him or her. Player 1 has the option to either remain anonymous or I could post the name. After the deposit is listed on the spreadsheet, anybody can challenge him/her by sending me a PM or posting on this thread and betting exactly the same amount as player 1. Then I will either use a random number generator or have a video of me flipping a coin (only if 1BTC+ though because I don't want to waste my time) to select the winner. The winner gets 99% of the pot and I keep 1% as a house fee.
How to read the Spreadsheet
Player 1: The person who started the round, could also be anonymous
Amount: The amount of money bet
Method: The method used to determine the winner random number generator (RNG) or coin flip with a youtube video (1BTC+ only)
Player 2: The person who plays against player 1
Winner: The winner of the round
Payout info: Blockchain.info link to prove the transaction was paid out
How the RNG method works
I use a random number generator with the option between 1 and 2. 1 Means player 1 wins. 2 means player 2 wins.
How the coinflip method works
I'll flip a coin while recording. Heads means player 1 wins, tails means player 2 wins. Video will be uploaded for all to see.
How do I know you won't cheat?
I will NOT be playing the game myself. That would be incredibly unfair. I have no reason to rig the game for anybody. https://docs.google.com/spreadsheet/ccc?key=0ArprjLNQsg4PdFVaMDhuVjJ4OHk1dm5fcFNoQ25ub3c
