As stated All Star Knockout Ultra Gamble is a game with low volatility, meaning players can land cash prizes more often, but perhaps not with the same big money win potential as those with high volatility. The slot itself is a five-reel game with 20 paylines, filled with retro symbols such as cherries, 7s, and stars.
The graphics are enticing in its simplicity as players will feel like they have been teleported to a retro TV set. The game has what feels like 1980's disco music, a talk show host voiceover at times and an aesthetically pleasing blue background with stars emanating throughout which compliment the colourful game symbols. Don't let the simple layout or the low volatility of the game fool you, the max prize is 4503x your stake, so there is plenty of opportunity for some big real money wins!
The smooth gameplay is complimented by some exciting features such as Random Bonus and the All Star Knockout Bonus. This is an online slot game that will suit all level of enthusiast, regardless of experience.
All Star Knockout Ultra Gamble is a very easy game to understand and getting started is very easy. The paytable and general game settings can be accessed by clicking on the triple line symbol on the top left hand side of the game. Online casino players first task will be picking a stake and these range from just C$0.20 per spin, up to the max bet of C$150.00.
As already stated the game operates with 20 paylines, on 5 columns and typically the name of the game is combining symbols from low paying fruit symbols, to the higher paying KO symbol which can reward up to 100x your stake. An additional facet of the game is collecting stars and these appear underneath the reels and as you spin you will notice these stars begin to accumulate, as you hit 5 in one section you will activate the Bonus Star Knockout function.
Autoplay is easy to access as well by selecting the play button on the right hand side of the reels, and on the left hand side of the reels is the Ultra Gamble button which can kick off the free spins level depending on whether you are successful or not with the gamble.
The main feature of the All Star Knockout Ultra Gamble slot is the suitably named All Star Knockout Bonus. This feature is kicked off when a player collects 5 stars beside a symbol under the reels. As players start the game 12 stars randomly land across the 40 spots on the board. As you continue to spin, stars will begin to appear and will drop randomly on this "star board" and once any symbol has five stars beside it, you will earn free spins.
The symbol that triggered the bonus disappears from this round, so it's far easier to combine other symbols as you negotiate this round. A random multiplier of between 2 and 5 is revealed before the free spins begin and is applied to any wins.
As you continue to spin more stars can appear which can mean that you can keep adding on free spins, thus increasing your chance of wins! If a player is lucky enough to combine another 5 stars with a symbol, this will also disappear from the game. This feature can lead to big wins as it is possible that there is only one symbol left if you are particularly fortuitous. Once the round ends, any five-star symbols have their stars removed.
One of the other features includes the aforementioned Ultra Gamble option. Click the Ultra Gamble button on the left hand side of the game, and for an additional stake, you can gamble on a mini wheel. If it stop on the colour green you get free spins, if it stop on red you lose your stake.
There’s also a random bonus feature which drops at any time during the game and this re-spins the reels for guaranteed wins. This function will continue until you don't win. Stars appear also during the random bonus feature so if you combine 5 stars here you can get even more free spins!
The game has 8 symbols with varying values as online slot players would expect with the lemon being the lowest value and the KO symbol being the highest - combine 5 of these on a payline and you can win up to 100x your stake!
This is a low volatility online slot, with a decent RTP of 96.1%. As previously stated the low volatile nature of this game can lead to more wins, but frequently these tend to be of lower amounts. Saying that, despite the low volatility, online casino players can still win big with a max win of 4503x your stake and a max cash win of C$675,450.
This is a properly fun retro slot game from Northern Lights and Yggdrasil, and its definitely one to check out for all levels of slot enthusiast. The graphics are extremely simple and smooth, and the gameplay matches this as it's a brilliantly easy game to play and understand.
The retro theme works really well overall and is complimented by some brilliant bonus features. The All Star Knockout Bonus, the random bonus feature and the Ultra Gamble option offers plenty of excitement throughout and crucially offer plenty of opportunities for some big real money wins.
Those of you who like a similarly retro feeling slot game, Yggdrasil's classic slot Joker Millions might be worth checking out.
