Free All Star Knockout Ultra Bonus slot
Please be patient, some games take longer to load than others!
All Star Knockout Ultra Bonus slot by Yggdrasil was developed by an in-house studio called Northern Lights and is an identical game to All Star Knockout slot. Here, you simply get an Ultra Gamble Wheel which is a feature purchase. You pay a fee depending on how many stars you've accumulated at that point, the more already present the costlier it is. A 50-50 gamble wheel will decide whether you get the free games and extra stars, or nothing. The game aside from this remains just as dreadful as the original and the RTP is 96.10% with no bonus buys, to 97.80% using the most expensive.
