Are you ready to rumble? You better put your boxing gloves on because ELK Studios are taking us ringside to Knockout Diamonds. This slot is a part of the Classic Series. ELK Studios have released several slots that mimick the style of the old school slot games. So far they have been fairly successful, especially with such titles as Diablo Reels and Hit it Hard. Most of these slots highly resemble the old fruit machines which you could find in your local pub or gambling establishment.

Knockout Diamonds has gone with a boxing theme. With all the latest fights between boxers and YouTubers, this seems like a very relevant theme to use. Knockout Diamonds is as classical as it gets, this slot uses a 3 Reel single line layout, so yes, there is 1 row and just a single possible combination way. It may sound rough for newer generation players, but this is exactly how it used to be back in the day. Nonetheless, this slot has a decent win potential of 2,500x, so single liners are not dead just yet.

Gameplay and Payouts

Knockout Diamonds has that bustling ambience of a land-based casino plus some additional boxing match crowd noises mixed in. Sound-wise it’s a very busy slot, but the slot’s model itself is rather simple. The slot machine is situated in the middle of the screen. It’s a single line slot which consists of three symbols. Above the reels, we see payout values for all the possible combinations. Below we see the current bet and the overall balance left, just like it is on a land-based slot machine. Knockout Diamonds background shows us the main boxing ring and the blurry stands around it. This presentation obviously is not the flashiest nor the prettiest, but for a classical slot, we didn’t have high expectations in the first place.

It’s simple, place a bet and match 3 symbols on the single row. Knockout Diamonds offers the classical fruit machine style symbols. Starting with the lowest value we have the knockout logo, cherry, “any bar”, blue bar, a green bar, purple bar, bells, number 7 and finally the wild symbol. You could call wild an addition of the new world, as these symbols didn’t make an appearance in the earliest slot machines.

If you know a thing or two about classical slots, then you should also know that payouts not always are the kindest. With Knockout Diamonds the situation is a bit different, overall the payouts are not that shabby. Sure, we are not looking at some huge numbers, but still, you have a good chance to toss in a single coin and receive some shiny gold coins in return. The max potential for Knockout Diamonds is 2,500x, while the bet range is 0.25 – 100, so the max win is 250 000. Volatility, of course, is high, being rated 8/10 by ELK Studios. The RTP is surprisingly decent, being exactly 96%. Perhaps the worst news is the actual Knockout Diamonds hit rate. We are looking at 12.8%, which could take us to the whole 12 rounds.

Bonus Features

What you don’t always see on classical slots are bonus features and on Knockout Diamonds, we have multiple ones. Wild symbol by itself is a new addition to these type of games, but they can also come with Multiplier Wilds of 2x and 3x, which then multiplies the whole line win.

The other helping hand comes from Ringside Rumble. Completely identical symbol sets on the 1st and 2nd reel will trigger this feature. In case of no winning combination, the third reel will respin 3 times while 1st and 2nd reels stay locked in.

Surprisingly, Knockout Diamonds also has a main bonus feature, which is called the Knockout Spins. This feature is triggered by 3 bonus symbols which are 3 Knockout Diamonds logos. Knockout Diamonds start with 3 Free Spins. Every new win or bonus symbol resets the Free Spin count back to 3. The main objective is to collect as many bonus symbols as possible. The more you collect the bigger the payout. Exact payout values can be seen above the reels. Award for 10 Knockout Spins symbols is the max win of 2,500x.


For a classical slot, Knockout Diamonds is a pretty decent game. The main game is as simple as it gets, just try to match 3 symbols on a single line. The addition of bonus features should be a welcoming sign for newer generation players, who number seven symbolotherwise would pass up on such games. When it comes to the design of the game, the whole boxing theme isn’t really that prominent. We have a couple of sound effects and the boxing ring in the background but that’s about it, so for boxing sport fans Knockout Diamonds will be a slight disappointment. Overall, Knockout Diamonds is a satisfactory addition to the classical series, it’s definitely not the worst of the bunch but also not the best.
