Another variation.

Hi,
In the top right corner it says "look out for mystery award". Was this to make this game more attractive or was there a mystery award? I have put some pennies through it but have only won a penny and got the ball back.
Thanks.

Without the benefit of an internal view, these were all standard mechs returning just one penny and a free ball so I would guess this is an operator note, as you mention junior, to make the game more attractive.

I guess the operator could place a token into the coin stack as the mystery bonus to eventually be paid to a player?
