All-Star Knockout Slot (Yggdrasil)

All-Star Knockout SlotAll-Star Knockout is a slot game that has been developed by Yggdrasil in partnership with Northern Lights Gaming. Yggdrasil seems to be following in the footsteps of Microgaming, who are known for the partnership while developing their games.

A Personal Review of This Classic Fruit Slot

Although All-Star Knockout is a classic fruit slot, Yggdrasil has incorporated some modern features which make it appear quite pretty.

All-Star Knockout is a 5x4 slot game which gives it a large gaming area unlike what you would expect in a slot that has 20 betting lines.

Fr the features, you will come across some free spins, a Random Bonus and 5x multipliers.

Betting and Prizes

After registering to play this slot game using my mobile phone, it was time to head to the gaming section to try my luck.  All-Star Knockout allows betting prices of between $0.20 and $400 per spin. Given that the slot game has a total of 20 lines, this translates to about $0.01 to $20, per line.  

I like the slots payscale, and on a lucky day, you can take home their top payout of 4,500x the stake. Although this is not the highest jackpot that I have seen around, it is quite good especially when you consider the game’s low to medium volatility.

The RTP is equally good, and currently, it sits around 96.09%.

All-Star Knockout Slot Features

I’m used to using the wild symbol in most other slots that I have played. However this is not the case with All-Star Knockout as the wild symbol is conspicuously missing, and it seems to have been replaced with another two features. One of these features appears randomly, while the other one via collected symbols.

The Random Bonus automatically gets activates when you lose some spins. It awards you with 3 win spins and each round comes with some sort of prize.  

The second feature shares a name with the slot’s title and it’s called a Knockout Bonus.  This feature is responsible for enabling you to collect some symbols from the slot’s reels. These are then added to the meters in the nearby reels, within the Award Board. To trigger the free spins, you are required to collect the attest 5 stars.

I managed to get this far and the slot game awarded me with 5 free spins that were accompanied by a random multiplier of 5x.

Theme & Design

If you enjoy classic fruit-themed games, then you will find this slot a lot of fun. Personally, I don’t, so I’m not quite impressed with the whole game setup.

Yggdrasil has used the Star symbol as part of the features, but additional features include the KO logo, Blue 7, Red 7, Cherries, Plums, White 7, Oranges, as well as some Lemons. The slot lies somewhere in between a modern slot machine, and a classic one.


I find all Star Knockout quite unusual and, honestly, I did not really enjoy the game. However, its good payout, excellent RTP, and low-medium volatility make it a good slot choice for players of all levels.
