I have thought of that as well. How many participants are you requiring before the game starts?
How many sets of games have you had already?
We just want to know if you got a lot of participants. It's actually the first time that I have heard about this kind of game and I find it interesting.
Today is the first round of the game and I had been testing for a few weeks at Rinkeby testnet till a few hours ago.
Game was already started 2 hours ago and you can check it on the website

Game will be started once I deposit 1 eth to the contract. and it will be end within 24 hours. Contract will automatically send prize ethers to the last address updated.
