The harder setting means you have to hit the spinners 10 times to get him to come up and then have to hit him seven times once he comes up in order to light the jackpot. I played a game where he came up after three shots to the spinner. The confusing thing is you are spelling out iron monger but there are only lights for monger so I have people asking me if the spinners are not registering. It is easier to follow now that the new code allows you to check your progress.
