What is the theme of Knockout Diamonds slot?

If I had to describe Knockout Diamonds in one word it would be ‘loud’. Forget the actual soundtrack, which is a combination of boxing ambient noises and some heavy rock. The real loudness comes from the design itself. Three reels are set on a roomy grid packed with numbers, symbols and a flashing digital sign. Despite the extreme visual business of the game, there’s a distinct lack of diamond symbols for a game called Knockout Diamonds.

The theme is undeniably a boxing one. You’ll even be treated to echoing narrations from the match announcer. Accompanying this theme is an old school classic feel. You’ll experience a much smaller reel set, only one possible payline (both in and out of the special features) and the symbols themselves are almost all throwbacks to the original one armed bandits.

The entire grid is set on a static image of a boxing ring, complete with spotlights and cheering crowd. The symbols are a combination on cherries, single, double and treble bars, lemons and Lucky 7s. The Lucky 7 almost makes it to the top of the food chain, surpassed only by the Wild symbol, which is capable of wins of 100 times your bet for three on a winning payline.

How to play Knockout Diamonds slot

Underneath all the flashing lights, dinging bells and spinning symbols, Knockout Diamonds has buried three separate special features. Read on to find out how one of your spinning punches can land you an extra lucrative bonus round.

Knockout Spins

Knockout Spins

This feature is undoubtedly the main event of the entire game. Aside from the fact that it’s where you can uncover a rewarding set of Free Spins, it’s also how you can trigger the game’s maximum 2,500 x payout. You can kickstart the Knockout Spins fight by lining up three Knockout game logo symbols (these are the Scatters). This sets you up with just three Free Spins, but you’ll get three more each time another Knockout symbol lands. Each Knockout Diamond collected will boost your strength with bigger and better wins. Collect 10 of them and walk away with the 2,500 x prize.

Ringside Rumble

Ringside Rumble

It took me a while to figure out how this bonus game is triggered. Essentially, all you need to do is land identical symbol sets on reels one and two.When this happens the two reels will lock into place and the third reel will spin alone three times. Your three respins will give you the chance to link up a final matching reel with Wilds or regular symbols for a very punchy payout.

Multiplier Wilds

Multiplier Wilds

This is the easiest feature to understand. Knockout Diamonds comes with both Wilds and Multiplier Wilds, either of which can substitute for any symbol except the bonus symbol. The Multiplier Wilds come in two varieties, either 2 x or 3 x your bet. If you land any of these in a winning payline then you’ll be rewarded with a boosted payout.

What is the RTP on Knockout Diamonds slot?

Canadian players who enjoy a longer spin session will be pleased to know that the RTP sits on an average and very fair 96%.

To give you an idea of Knockout Diamond’s payout style, we need to look at the fact that it ranks an eight out of ten on ELK’s volatility scale. That means less frequent wins, but arguably larger prizes when they do come around. This makes it most suitable to players who plan to stick around for more than just a handful of spins. If you choose to play then you can get started from C$0.20, up to a maximum of C$100 per spin.

Next in the ring are the symbol values. As you might expect, these range from low to high in value. At the bottom of the heap are the bells and cherries. What you really want to match up are the Lucky 7s. To make a full line you’ll need three Lucky 7 symbols for a healthy winning scoop at 75 x your bet.

Even better would be to land three Wilds for a KO punch of 100 x your bet. During my testing I found that the Knockout Spins were really tough to trigger. I had all but given up before I finally lined up the necessary symbols. The truth is that it was worth the wait. I retriggered the game two times over and walked away with a really big win off a C$2.00 bet.

Final Verdict

Knockout Diamonds


If you made it all the way down to the bottom of this review then you must be dying to know what we think. The fact is that Knockout Diamonds should have been a very boring and cliched game. In actual fact I found my self quite riveted by all the flashing symbols and noisy cheers. Once I got used to the gameplay and how the features are activated, I was more than happy to sit tight for a while.

It’s true that the Knockout Spins are tough to trigger. It’s also true that the 2,500 maximum payout isn’t the highest out there. But in practice the features are very rewarding once you successfully see them in action. The possibility of a re-trigger also helps to increase the final prize. I believe Knockout Diamonds is a bit of a hidden gem, and if you’re lucky to get into the Free Spins early on, you’ll get to the prize money with barely a bruise.
