All Star Knockout Slot Review

Yggdrasil has brought you many fun slots in the past, but this time working closely with the novice studio, Northern Lights Gaming, they’ve taken it back to basics with the All Star Knockout slot.

It’s an expanded fruit slot that offers 5 reels and 4 rows instead of the traditional 3×3 setup. But does it have what it takes to beat a classic fruit slot? Let’s find out in our All Star Knockout slot review.

All Star Knockout Bonus Features

The All Star Knockout bonus features aim to knock out symbols from the reels using the Northern Star icons. When they appear on reels, they are collected in one of 4 scoreboards. Also, there are two bonus games that we will cover further down this All Star Knockout review.

It’s also worth noting that if you change bet levels in the All Star Knockout online slot game, then your star collections will be reset to zero. However, if you go back to the previous bet level, you’ll see the game has saved your progress.

Random Bonus Feature

As you play, a losing spin will trigger the All Star Knockout free spins feature aka the Random Bonus feature that comes with up to 3 free spins. The best part is that you’re guaranteed to win from these free spins – the reels will keep on spinning until they land on a winning combination.

All Star Knockout Bonus Feature

To activate the All Star Knockout Bonus feature, you need to collect 5 stars in one of the above-mentioned scoreboards. When you amass 5 stars next to one of the symbols in the scoreboard, you’ll trigger 5 free spins. During this feature, you’ll also have a random multiplier of up to x5 applied to the spins.

Stars will keep showing up on the reels during the free spins, which can help or hinder your efforts to win. Five or more stars will remove a certain symbol which is great if you’re trying to get rid of any lower-paying symbols. But not so great if they knock out something that pays out more.

All Star Knockout Jackpot

There isn’t an All Star Knockout progressive jackpot, but the maximum win of 4,500x times your stake makes up for it if you play with a max bet.

RTP and Volatility

The All Star Knockout RTP works out at 96.09%, which is pretty decent and above the industry’s average. The All Star Knockout volatility is considered to be low, which makes sense considering the old school appeal of the game itself. Plus, you’ll be landing lots of small wins in the process.

All Start Knockout Bonus Spins

As easy-going as it sounds, the slot is still worth playing for fun first before you risk your real money. To test the slot, seek out some All Start Knockout bonus spins at the top UK online casinos. Dunder and LeoVegas, for example, offer no deposit bonus spins on registration to test their online slots for free.

All Start Knockout on Mobile

If you’re a mobile casino slots player, you can take the All Star Knockout slot game with you at all times. It works just fine on all handheld devices including Android, iOS and tablet.
