Knockout Diamonds slot review

ELK Studio has long since demonstrated their talent for twisting the classic slot genre into very playable and unique games. Knockout Diamonds is no exception, and you’ll get a mix of fruit machine nostalgia combined with a ringside boxing match experience here. Granted, there are no actual fights going on in that ring, but it’s fun to hear the speaker grandiosely announce the features you trigger.

Why someone would place a slot machine ringside is another question, but it all works out pretty well. You can place bets between 25p and £100 per spin, which is decent, and the max win is capped at £250,000. The paytable is on display above the reels, and the top payer is the wild symbol offering 100x for 3 on a row. Anyone interested in the retro experience, albeit with a modern twist, should definitely check this one out. .

Knockout Diamonds Slot Reel Screen

Knockout Diamonds Features

Whenever you land matching symbols on reels 1 and 2, you trigger the Ringside Rumble Respins. You will then see reel 1 and 2 lock in place, while the third reel respins 3 times. This feature is basically an extra chance to land a winning combination.

In this game you will also benefit from multipliers that can hit all the reels to increase your winnings by 2 or 3 times. Of course, the wild multiplier also comes in for all regular characters, just like regular wild.

You will also benefit from multiplier wilds in this game, and these can land on all reels to boost your winnings with either 2x or 3x. Of course, the multiplier wild also steps in for all regular symbols, just like the regular wild does.

You will collect any bonus symbols that land, and this will lead to a jackpot prize that’s paid out in the end. You can check out the Knockout Spins paytable above the reels, as this will tell you how much you’ll win per collected bonus symbol.

We’ll reveal it for you here also, and the fixed jackpot prizes you can land are as follows: 5, 10, 25, 50, 100, 250, 500 or 2,500 times your stake when you collect 3, 4, 5, 6, 7, 8, 9, or 10 bonus symbols, respectively. You can also win the top 2,500x jackpot by landing 3 bonus symbols on the same Knockout Spin.

The 200 Spins Knockout Diamonds Experience

It’s amazing how a 1-line classic slot can sound so complicated when you read about. However, it’s much easier to get the gist of it by simply playing. You can also check out our 200 spins highlights video below to get a visual feel for how the game plays out. We’ve edited out all the boring parts, and the video is less than 2 minutes long. ere, and you can win up to 2,500x your stake.

Review Summary

Knockout Diamonds will appeal to all fans of classic slot machines for sure, and the boxing ring theme frames the game pretty well. It’s cool to hear the speaker announce the different features, and you will get plenty of the Ringside Rumble Respins to help you along. In the middle of the ongoing struggle for evermore win ways and reels, ELK Studios’ Classic Series can be a welcome break.

The gameplay is a lot simpler than it might sound when you read about it, and it’s really all about the Knockout Spins. Granted, the 2x and 3x multiplier wilds can lead to some decent base game payouts, but the real thrillride comes when you collect bonus symbols to go for the one-punch 2,500x KO. Amongst classic 3-reelers, Knockout Diamonds is a pretty solid alternative.


  • Ringside Rumble Respins
  • Multiplier wilds of 2x and 3x
  • Free spins with symbol collection
  • Up to 2,500x symbol collection jackpot prizes


  • Will not appeal to players who dislike classic slots and/or boxing

If you love Knockout Diamonds you should also try:

Win Win - is something as rare as a classic 3-reeler with the possibility of “indefinite” free spins. The bonus round also comes with a progressive win multiplier, and this can lead to payouts up to 5,000x your stake. This is one of the best in ELK’s Classic Series in our humble opinion.

Hit It Big - is also part of ELK’s Classic Series, although it plays out on 5 reels, 3 rows and 5 paylines. The Game Show feature can land you the big prize of 2,500x your stake, and you will also benefit from 4 unique base game features here.

Hit It Hard - is ELK’s follow-up title to the one above, and it comes with multiplier wilds up to 5x on the third reel. You can also look forward to a Dice Bonus Board Game with 7 extra features. The volatility is medium to high here, and you can win up to 2,500x your stake.
