All Star Knockout Slot Review

From first glance, All Star Knockout appears to be a retro online slot; something that wouldn’t have been out of place at an online casino in the early 2000s.

However, Yggdrasil have intentionally developed this release with the classic casino-theme in mind to potentially appeal to the nostalgic gambler, whilst introducing a few special features that fans of more modern slots will also enjoy.

With a gameshow-esque soundtrack playing in the background, your goal is to rack up Bonus Stars on the Award Board to trigger the Free Spins on All Star Knockout where you will have an even greater chance of landing some huge wins.

Obviously, the base game can be rewarding in itself, but it’s these special features that make this Yggdrasil online slot one that you’ll want to play.

Make sure to continue reading our All Star Knockout review to discover precisely what these features do and how they’re activated.


All Star Knockout Features

The idea behind this slot is that the majority of the special features come together to eventually result in a number of Free Spins being awarded.

Whilst there is a base game feature that can provide up to 3 chances of hitting a winning combination, there isn’t necessarily another All Star Knockout bonus to speak of.

We would have liked to have seen some Wild symbols incorporated into this slot as they’re becoming a staple of any modern release.

Bonus Stars

When you initially load up All Star Knockout for the first time, or when the the Award Board is completely empty, you’ll receive 12 Bonus Stars. These populate the Award Board at random and cannot trigger Free Spins.

Award Board

Below the reel set lies the Award Board. There are 5 spots for each award, each of which can be filled up with stars.

Whenever a Star symbol lands on the reels it will transfer to a random position on the Award Board. Your goal is to completely fill 1, or more, of these awards to activate the All Star Knockout Free Spins feature.

Note that the Award Board remains persistent per stake and stars will not be transferred when altering your bet.

All Star Knockout Free Spins

When one, or more, award is filled up with stars, the All Star Knockout Bonus is triggered. You will receive an initial 5 Free Spins for activating this feature, along with an additional 2 Free Spins for every other award that is completed, before or during this feature.

Any award symbol that starts the bonus is removed from the reels for the entirety of your Free Spins. Any subsequent awards that are filled during Free Spins will result in additional symbols being eliminated – increasing your chances of hitting a big win.

Before the All Star Knockout Free Spins begin a multiplier ranging from 2x – 5x is selected and will be applied to all wins until the end of the bonus.

We found this to be a feature that has incredible potential. Imagine you are awarded a 5x multiplier and you manage to eliminate every single symbol, except the premium KO symbol, you’d be looking at a reel set entirely populated with the most valuable payouts!

Random Guaranteed Win Spins

As we touched upon earlier, the base game isn’t devoid of any special features. There is, in fact, a random bonus that can be awarded after any losing spin.

If this activates, a guaranteed win spin will occur. You can receive up to 3 spins per bonus and this can also trigger the All Star Knockout Free Spins feature.

Gamble Feature

Depending on which online casino you play at, and also your country of residence, the gamble feature may be enabled.

You can use this to guarantee entry into the All Star Knockout Free Spin bonus, but the cost of doing so will depend upon your chosen stake and the current state of the Award Board.


All Star Knockout RTP & Technical Data

All Star Knockout is considered to be a medium variance online slot; rated at 71.5 on Yggdrasil’s volatility scale. Additionally, it has a 96.1% Return to Player (RTP).

The reel set layout contains 5 Reels, 4 Rows and 20 Fixed Paylines.

All Star Knockout has the following hit frequencies:

  • Any win: 33.8%
  • Entry Into Free Spins: 1 in 49

Bet Limits

Similar to all of Yggdrasil’s online slots, All Star Knockout has a decent range of betting options for you to choose from.

New customers can spin with smaller stakes by playing with the €0.20 min bet, whereas those of you who prefer a high risk versus reward approach can deploy the €400 max bet.

There are many additional stakes in between these limits, so you’ll be sure to find a wager that you feel comfortable playing with. All of these are listed in the table below.

2€0.40

Maximum Win

If you manage to land a knockout blow on this slot, you can potentially walk away with a default maximum prize of up to 4,500x your total stake.

In pure cash, All Star Knockout’s default maximum win is €675,450 – a fantastic amount of money to be won that’s more in line with a modern online slot title, rather than one that looks like it could’ve been released at the turn of the millennium.


All Star Knockout On Mobile

If you’re looking to fit in a few spins during a break at work, or when you’ve got a spare few minutes, you’ll be glad to hear that All Star Knockout can be enjoyed on the smaller screen.

This online slot is compatible with Android and iOS smartphones or tablets, along with a range of other market-leading devices.

Grab a deposit bonus at one of our recommended online casinos, which are fully mobile compatible, to get the same great slot experience. Just make sure to take a look at the terms and conditions to see if there are any wagering requirements!


Xpert Verdict

Yggdrasil have released many creative games in recent years, which incorporate a number of innovative features for you to trigger. The release of All Star Knockout sees this provider take a much more classic approach to online slot gameplay, whilst including various bonuses that can generate some fantastic payouts.

We believe that although this slot will appeal to those of you who have played similarly themed games before, it doesn’t necessarily have the initial attraction that will draw in a great deal of new players.

The visuals are hardly groundbreaking and the theme has been done time and time again.

However, if you do decide to give All Star Knockout a go, you won’t be disappointed. This slot delivers regular base game wins often enough to keep your account balance ticking over as you go in search of the highly lucrative Free Spins bonus.

When this feature does trigger, you’ll be counting your lucky stars as the Award Board fills up to eliminate extra symbols and improve your chances of hitting a win. Additionally, the multiplier that’s awarded at the beginning of the bonus serves to greatly enhance your overall payouts.

As you’ve probably heard before: you should never judge a book by its cover. This is certainly something that should be applied to All Star Knockout. Although it may not appear to be particularly interesting at first, you’ll soon discover how much fun this slot can be and the 4,500x top prize is certainly worthy of a 2020 release.

Overall, we give Yggdrasil’s latest title two GambleXpert thumbs up and a solid recommendation. Try it for yourself to see if you can hit that 5x multiplier
