A good friend of mine who I bought the little slot machine off has one of these little badboys.
this was also a trade stimulator but I believe it is a skill type? from what i have researched abut trades stimulators
they had a few classes for trade stimulator
gambling which is the type I showed before and then skill types like this game below
Any ways the idea of this game is you have some ducks in the back and you put a penny in the gun and you shoot the penny at the duck, if you hit the duck you get a gumball and your penny back if you miss you only get a gumball and you loose your penny.
