in a casino, and you decide to play a game on one of the casino's computers,
just like you might play solitaire or chess. The computer can make moves in the game, just like a human player.

and the computer will play first. It can choose to flip the coin or not,
but you don't get to see the outcome. Next, it's your turn.
You can also choose to flip the coin or not, and your move will not be revealed to your opponent, the computer.
Finally, the computer plays again, and can flip the coin or not, and after these three rounds,
the coin is revealed, and if it is heads, the computer wins,
if it's tails, you win. So it's a pretty simple game,
