That's gross. Plus, in a well-maintained revolver, the single bullet will usually drag the spinning chamber to the bottom, making that the smart move. That doesn't seem to be a factor here.
It's always the smart move even if it's totally random, anyway, isn't it? 1/6 chance instead of at least 1/5? You should get more points if you don't spin.
Good game, nice music. But why does it matter whether you spin the chamber or not? How does it change the odds Fridge? (maths never was my strong suit)
