All Star Knockout Slot Review

Introduction to All Star Knockout

When I first opened All Star Knockout, it looked like a straight-up retro fruit machine. On the surface you get classic slot symbols, simple 3D graphics and a blue background with a white explosion effect behind the reels. After a few spins, though, the Award Board packed with stars at the bottom of the screen and the constant hint of bonuses made it clear this is more than a basic three-reel throwback.

All Star Knockout is a 5x4 video slot with 20 fixed paylines, created by Northern Lights Gaming in collaboration with Yggdrasil. You spin from 0.20 a go up to a chunky 400 per spin, so it caters for low-ball sessions as well as serious high-roller play. The top win sits at 4,500x your stake, which is pretty generous for a game that leans towards low to medium volatility.

How to Play All Star Knockout

Playing All Star Knockout is very straightforward. I pick my stake using the plus and minus buttons, then hit the large spin control on the right. There are 20 fixed paylines, paying left to right, and you need at least three matching symbols on a line starting from reel one. If I want to grind the game, I use the auto spins tool and set anything from 10 up to 1,000 automatic spins with a chosen total stake.

RTP & Volatility in All Star Knockout

All Star Knockout comes with an RTP of about 96.09% to 96.1%, which is bang on average for this style of video slot. Official literature puts volatility in the low to medium range, and that matches what I see in practice. Wins come around fairly often, especially smaller line hits, so the balance does not fall off a cliff as quickly as on some high variance fruit slots.

Because the variance is on the gentler side and the hit rate feels decent, I tend to stretch sessions out and ride the features rather than hunt for one monster spin. The 4,500x maximum win is still there if the free spins and multipliers line up, yet the game also works nicely for shorter, lower-risk play, which suits players with more limited bankrolls.

Stake-wise, All Star Knockout lets you set wagers from 0.20 up to 400 a spin, or 150 at some casinos, using the stake control on the main screen. That means casual players can spin for pennies while high rollers can push serious amounts through the game. There is no progressive jackpot, but the advertised max win of about €675,450 on a full-power setup shows what the free spins, multipliers and stacked symbols can do.

How to Win on All Star Knockout

To get paid on All Star Knockout you line up the eight regular symbols across the 20 paylines. The deck is classic slot all the way, with lemons, plums, oranges and cherries at the lower end, then blue 7, white 7 and red 7 as the higher regulars. The standout icon is the KO game logo, which is the most lucrative symbol and pays up to 5x your total stake for five of a kind on a line.

There are no wilds in All Star Knockout, which keeps the paytable very clean. All symbols can land stacked in sets of one, two or three, so full-screen hits are possible when the reels line up. I often check the paytable by tapping the information button, as the payouts for every symbol combination update dynamically when I adjust my total bet, which is handy for seeing exactly what each line can return.

The real key to bigger returns lies in how the symbol collection works on the Award Board. Each symbol has five empty star spots beneath the reels. Whenever a star icon lands, it gets added to one of those symbols at random. Filling all five stars for a symbol not only triggers the All Star Knockout Bonus but also removes that symbol from the reels during the feature, which can thin out low pay icons and help stronger combinations land.

Free Spins and Bonuses in All Star Knockout

All Star Knockout actually has two main features that keep the base game ticking. First up is the Random Bonus, which can trigger after a losing spin. When this kicks in, you receive win spins that guarantee at least one paying result. The reels keep going until there are no more wins, so even a dry patch in the base game can flip into a small streak out of nowhere.

The highlight for me is the All Star Knockout Bonus. Once any symbol on the Award Board collects five stars, you get five free spins. Before they start, the game picks a multiplier of x2, x3, x4 or x5 and applies it to every win in the round. During these free spins, more stars can land, filling other symbols and adding extra spins while knocking those icons off the reels once they hit five stars.

Overall Review of All Star Knockout

From a pure visuals standpoint, All Star Knockout is not going to blow anyone away. It looks like an older retro-themed slot and the graphics are fairly basic, even if the jazzy 70s soundtrack and animated effects give it some charm. Once I got past that, the Award Board, the star collection and the guaranteed win spins made the gameplay feel much more engaging than the simple fruit machine styling suggests.

For me, the mix of low to medium volatility, frequent smaller hits and the chance to grind towards those five-star awards works really well. You can build up several symbols near the trigger point, hit one bonus, then watch others fill during the free spins for extra rounds and better symbol sets. All Star Knockout will not suit everyone, but if you like classic slots with a twist and decent 4,500x potential, it is well worth a session.
