the machine is a Olympia evaluational model. It says King Shark on the tag on the front of the machine it says Crafty Shark Kingdom it is totally written in Japanese or Chinese not sure which. I don't know a thing about this machine if it has a story or anything. All i can do is put in the tokens and push the bar down and stop the wheels. I wish i knew anything about the machine. Do You know anything about the machine :-?
