In the event I guess I shouldn't have been surprised that Williams decided to chop a few of the craziest wins out of the game upon it's on-line release - they did the same with the original Wizard of Oz after all. When those bubbles start landing on the screen don't get your hopes up for that five reels wild hit then, because it's simply not in the game - the maximum is four reels wild and the maximum multiplier has been reduced from 10x to 5x in this version as well. What a cop out!
So much of the games RTP is tied up in the bonus rounds that it's a real struggle to get yourself in front from the base game alone and if you don't get lucky with the Ruby Slippers feature you'll find your bankroll running down very fast indeed. Also, like many WMS games the jackpot symbol does not award a win if the line features any wild symbols so you'll be praying that you DON'T see any of those during a stacked wild spin as they will serve only to block other winning combinations. I hate the fact they did this and it's nearly enough to make me not want to play the game at all.
Overall Ruby Slippers feels like a huge disappointment to me and I really think this shows that Williams are much more interested in the Las Vegas / land casino market than their on-line fan base.
