Provable fairness for multiplayer games ?

[MrDrowner]

Hello everybody,

"Provable fair" concept became very clear within last years for classical gambling between player and house. There are already standards known both by industry and most players.

However, what is "provable fairness" for multiplayer games such as poker, where betting is between players rather then between Player and House ?

I'm interested in it because some people ask either our game https://drownhim.com is provable fair ?

What we could do in this case to prove our fairness ?
