Lucky coin

You are the player at the right in the bar in 1899

An enemy sits right in front of you, he puts a gun in front, the gun has live as well as blank rounds inside, and he challenges you to test your luck.

A coin is tossed every time to see who will pick the gun up, after picking up the gun you have the option either to shoot yourself or shoot him. You bet on if it's a live round or a blank round. You turn stays if it's a blank round and you shoot yourself, if not well...at least you have 3 hearts. If you shoot the enemy with a live round, his one health vanishes. You have to kill him 3 times to win

Test your luck to see if you can defeat the enemy without dying.
