ethCasino POC

ethCasino is a hub that allows users to launch Games from the casino offering.

For this POC I have implemented a TicTacToe 2-player game (that doesnt rely on randomness).

The idea is that players can bet some ether, which is frozen during the game, and gets released to the winner, or splitted in case of a draw. Each game is a new smart contract deployed by the Casino smart contract the UI connects to.

The Casino contract keeps track of the active games and redirects the users to the actual game's smart contract address.

It is also funny to see the drastic effect of the gas fees on bets under 10 ether, but it is annecdotical for this POC.
