I'm on level 2064 and have never hit the jackpot. The odds are 8 to 1. Usually no matter where the jackpot is when I stop the spin I get the lollypop hammer 50% of the time. COME ON!
That's the problem with the booster wheel in general, it makes you think you have an 8 to 1 chance but the reality is that the wheel is just there for aesthetics. As with anything electronic, I imagine the outcome will be determined as soon as you hit spin.
