I would reccomend doing it with two fakes, the first one you pass back if it's a fake I'll generally unlock it.
Then the fun begins, I'll often start to have some fun then.
Maybe tweak the odds for or against you you wont know.
I currently have someone I'm playing card roulette with 6 cards one of each type.
The reset is the live bullet, if they hit that the whole thing will start over.
I made the cards visible for that one so he can see his odds as he draws 💕
