Knockout Diamonds Slot Online

Put on your boxing gloves and meet the Knockout Diamonds slot game, the eight title in ELK’s portfolio of classic-themed slots. Even though we’re not associating this developer with classic titles, they’re showing that they can merge two completely different topics and gamify the content.  With only one active payline, this slot game pays relatively well, precisely up to 2,500x your bet. This attractive payout is triggered with multiplier wilds, respins and free spins as bonus features. Find out how they work in our detailed Knockout Diamonds Slot Review.

About Knockout Diamonds Slot

The Knockout Diamonds slot takes you to a boxing ring where the biggest superstar is the retro slot machine on 3 reels and 1 active payline. In this match, you’ll have the opportunity to spin the reels and win pretty decent prizes. It’s not called “A Knockout” for no reason, since it includes Ringside Rumble feature and a Knockout Spins round, where you get to spin the reels for free.
To start the first round of spins, make sure to set your preferred betting level ranging from £0.25 to £100 per spin. This level gives you more than enough options to place your desired bet, even if you’re not one of those players that sets the stakes to a maximum level. In the settings, you can activate the Quick Play option or select the auto spins mode which allows you to place up to 100 auto spins. The Knockout Spins will bring maximum win potential and action on the reels, offering you a chance to win up to 2,500x your bet, which you can trigger in multiple ways. We’ll elaborate these features in short, now, onto the template and features.

Design, Symbols and Graphics 

As the title announces, this game is all about the action, strength and excitement happening on a boxing match. The graphics are impressive, and the overall template looks very clean and sharp. The developer didn’t want to go over the top with the reel setup and allowed the traditional slot machine to shine in the spotlight. The sounds and music in the background are ambient, noisy and authentic for the overall competitive, boxing ring atmosphere.

The paytable contains a set of classic fruit symbols, along with the wilds and scatters that give the general identity of the gameplay. In order of values, we have the cherries, single double and treble bars, lemons and lucky 7s. The lucky 7 symbol pays up to 75x your bet for 3 of a kind. The wild symbol is represented with the Knockout Diamonds logo which triggers the knockout free spins session. This symbol might come with a multiplier attached to it and pays 100x your bet for 3 of a kind before you proceed with the bonus game. We have to admit that this is pretty impressive for a slot game that looks relatively simple and modest.

RTP, Variance and Payouts for Knockout Diamonds Slot 

The Knockout Diamonds slot’s RTP is capped at 96% which is the industry average for online slots. Regarding the math model, the game’s variance is set to high, rated with 8 out of 10 from the slot analysts. The hit rate of 12.8% is relatively low so expect a few lost rounds before landing a winning one. This means that on average you’ll land a winning line once on every 8 spins. However, these insights are theoretical and based on over million spin tests, so it might not be the same for you once you start the game. As we’ve mentioned above, the most you can win from a single spin in this game is 2,500x your total stake. You can read more about different math models in online slots in our detailed Variance, Volatility and RTP guide.

Gameplay and Features on Knockout Diamonds Slot 

This boxing-themed slot match comes with a couple of bonus features. As we’ve mentioned, few of them are pretty standard. The multiplier wilds feature will squeeze the most out of the spin potential, while the Knockout Spins is the classic free spins round found in many slot games. The Ringside Rumble feature allows you to respin the third reel if you’re waiting for a matching symbol. Let’s explain the bonus features in more detail:

Multiplier Wilds Feature

Generally speaking, the wild symbol serves as a substitute for all standard symbols when it makes up a winning combination, and the Knockout Diamonds slot is no exception. In this game, wilds come with a 2x or 3x multipliers that maximise your total score. 

Ringside Rumble 

This feature comes into play once you land identical symbols on reels 1 and 2. When this happens, the first two reels lock for 3 consecutive respins. This gives you the chance to link up the third required symbol or go with a wild one.

Knockout Spins

This feature is triggered once you land 3 Knockout Spins symbols on the active payline. The goal in this game is to collect as many Knockout symbols as you can. Each time you manage to land one of them on the reels, the number of free spins resets to three and then the symbol is added to a meter. To trigger a prize, you need to collect at least 3 Knockout symbols to win 5x your bet. For a maximum of 10 symbols, you’ll land the big prize capped at 2,500x your bet. Another way to trigger the 2,500x jackpot is by landing 3 Knockout symbols in a single spin.

Knockout Diamonds Slot on Mobile 

You’ll receive the same high-quality design and animations of the Knockout Diamonds slot when you play it from a mobile device. The game is developed with HTML5 which allows it to adjust on any small screen. You can easily access the game on any Android, iOS and Windows device where it will work and play very nicely.
