To play the game, one of the players—either the user or the program—has to go first. Alternatively, we can use a probability to make the choice. For example, we can give the same choice for two players, i.e., 50/50 odds by default. Or, we can give the program a better choice of going first, i.e., giving the house a slight edge.
So in the above context, what is the meaning of house? I can't understand the usage of house here.
Sorry for my poor English to adapt the original for the above context.
Thanks in advance.
