The All Star Knockout: Ultra Gamble slot game is produced by Yggdrasil Gaming. Yggdrasil Gaming take their name from Norse mythology where Yggdrasil is a magical tree where dragons lived and Odin sacrificed himself. Yggdrasil Gaming are one of the smaller slot development companies on the market at the moment – primarily focusing on lottery and scratch card game – and do not offer a full casino platform. They lease their games out to casinos using other platforms as a bolt on package. Yggdrasil Gaming publish the Return to Player/House Edge of their slots games within the game help file. The House Edge of All Star Knockout: Ultra Gamble is 3.9%.
All Star Knockout: Ultra Gamble is a 5 reel game that is 4 symbols high. It has 20 paylines, playing from left to right.
The All Star Knockout: Ultra Gamble slot is essentially a traditional fruit machine. You get the symbols you would normally associate with the kind of slots normally found in pubs and bars.
Wild – There is no Wild symbol in this slot.
Stars – Stars symbols can land on any part of the grid and when they do they will be added to the award board that sits beneath the reels. They will fill up random blank stars on the award board and once on set of stars has bee filled you will trigger the All Star Knockout Bonus. At the start of your spins 12 stars will be added to the award board and once you trigger the All Star Knockout Bonus the stars that did so will disappear.
All Star Knockout Bonus – If you trigger the All Star Knockout Bonus you will be given 5 Free Spins, with an additional 2 every time you manage to fill up another awards board during the feature. Any symbol that is filled with stars on the awards board will be removed from the spins and before the feature begins you will be awarded a multiplier of x2, x3, x4 or x5 the bet on every winning spin.
Random Bonus – There is a random chance that the Win Spin Respin feature can be trigger on any of your spins. If this happens you will be guaranteed a spin that results in a win. The reels will spin again and if you win again the will spin again, but if you do not the feature will end. As long as you keep winning, the reels will keep on spinning.
Low Spin Bonus – If the total number of stars on the awards board is between 1 and 4 then you will respin will be awarded with additional stars added to the reels to help fill them up.
Gamble Feature – At any point you can choose to gamble to play the Free Spins. The amount you need to pay will be dependant on the size of your bet and on the number of Bonus Stars already collected. Without any stars you will pay 5.6x the bet. However, this amount will increase as you collect Stars. If you change the size of the bet the number of stars collected will reset, as will the amount you need to pay to play the Free Spins. Return to any previous bet amount and the number of stars collected will be saved, meaning the mount you pay to play will also revert back.
Of all the slots that Yggdrasil could have decided to revive, this is probably the one I could have done without. I won’t lie, this is a departure for Yggdrasil. I expect slots that look incredible and perhaps that is because the software giants have spoiled us over the years, but compared to previous games this one really doesn’t come close. Given that this little more than a traditional fruit machine there isn’t too much going on here to discuss in terms of features either. The star collection is engaging but it is still pretty rudimentary in the grand scheme of things. What makes this slot different to the original is the addition of a pay to play feature, something doesn’t add enough to make this one we’ll ever get all that excited about. The house edge is offering decent value but nothing to get all that excited about.
