Knockout Diamonds Slot Review

ATF: ELK Studios went with the 'less is more' mantra when designing the Knockout Diamonds slot machine game, and the strategy worked remarkably well. While the slot bears only 3 reels and a single payline, you will be blown away by the cutting-edge graphics that bring the game to life.

Better yet, the bonus items sprinkled throughout the gameplay level up the entertainment factor and open you up for more money-making opportunities. Get ready for knockout rounds in this heavy-duty mashup of a classic fruit machine and bonus video slot where you can collect up to 2,500x your bet.

Are you Ready to Rumble?

Who knew that a classic slot machine and a boxing motif would play well together in a ring?

The immersive Knockout Diamonds online slot is proof that Elk Studios is the master of seamlessly evoking the classic slot machine nostalgia in a high-octane modern video slot environment. This heavy hitter is the 8th installment to be released in the ELK Classic Series slot machine collection, and it's easily the best release yet. Wear your boxing gloves, and channel your inner Mohammed Ali to prove that you're worthy of the 'world's greatest' moniker in the ring! 

Fire up the reels of the Knockout Diamonds slot online, and you'll be ushered into the boxing ring with cheers and jeers from an excited crowd ready for an adrenaline-filled fight. The action unfolds in a classic 3-reel grid arrangement and only one payline, but don't let that simplicity fool you into underestimating the slot casino game. Elk Studios further instilled the old-timer slot machine thematic concept through familiar fruit machine symbols like the Lucky 7, a bell, three different types of BAR symbols, and cherries. However, your key to winning this fight is through the wild symbols and the knockout bonus symbols, which we shall discuss later in this Knockout Diamonds review.

Punch your Way to Victory in the Ring

As intimidating as the ring of the Knockout Diamond slot machine game feels, you'll be happy to know that this online casino game has enough room to accommodate all types of fighters. Starting at only 1 coin to a maximum of 100 coins per spin, the betting range is flexible enough for both high roller gamers and casual reel spinners. It's not the size of the dog in the fight but the size of fight in the dog that matters, right? Even so, bear in mind that the bigger your expenditure on the reels, the more money you'll bag from winning combinations. 

Coming with medium to high volatility and a high 96% RTP, ELK Studio's Knockout Diamond slot game is a promising title that won't leave you empty-handed. As long as you make your every punch count and duck at the right time, you'll last long enough in the ring to rack up huge payouts. Below is a quick overview of the game's paytable indicating what you'll collect for arranging matching symbols across the single payline:

Two on a Payline
Three on a Payline
Lucky 7
Triple Bar
Double Bar
Single Bar
A Mix of Bars
Knockout Diamond
2,500x (during the Knockout Spins)

Boost Your Stamina to the Final Round and Win Big!

As any boxing trainer who knows their stuff would tell you, precision is everything when you're in the ring. And that's exactly what you should do when you play Knockout Diamonds slot online. Know when to throw an uppercut, a stunning left jab here, a right hook there, and when the opportunity comes, your knockout blow should come in to cement your victory. Here are the power-up features you should arm yourself with when the spotlight shines on you in the boxing ring:

Win the Maximum Payout in Knockout Spins

Line up 3 Knockout Diamond icons on the payline, and you'll initiate the Knockout Spins fight, which awards you 3 free spins. Through this feature, you get an opportunity to play Knockout Diamonds for free and still win real money. During the Knockout Spins round, the free spins counter will reset whenever you form a winning combination on the payline to earn you more reel-spinning sessions. 

Landing a Knockout Diamond symbol will also reset the free spins counter, and on top of that, this special symbol will also boost your energy for throwing a heftier knockout punch. Every additional symbol you collect gets you an instant bet multiplier, ranging from 5x, 10x, 25x, 40x, 100x, 250x to 500x for 3, 4, 5, 6, 7, 8, and 9 extra Knockout Diamond symbols, respectively. 

Collect 10 of these special symbols, and you'll scoop the maximum prize of the game, which is a gigantic 2,500x your wager! Moreover, if you're lucky enough to land three Knockout Diamond symbols on the one payline during the free spins bonus round, then you'll instantly slingshot your way to the game's maximum payout! How's that for a K.O.? 

Form More Winning Combos in the Ringside Rumble

ELK Studio's Knockout Diamonds slot machine packs some more punch through the Ringside Rumble feature, where you can collect respins for more money-making chances. The feature becomes active when you line up identical symbol sets on the first and second reels from the left. The two reels will then lock into place, and you'll earn three respins on the third reel that is free to spin.

Escalate your Payouts with Multiplier Wilds

This ELK Studios heavyweight also comes with x2 and x3 Multiplier Wild icons that appear at random to double or triple your payout from matching the symbols on the reels. Like the standard wilds in the game, these Multiplier Wild symbols will stand in for all other in-game icons, apart from the bonus symbols.

Get Into More Fights on the Reels or Go Back to Basics

If you enjoyed ELK Studio's captivating boxing extravaganza, then you'll be impressed by Fugaso Gaming Solutions' KnockOut online slot. This title is a bonus-packed 3D number inspired by the UFC where you could win up to 5,000x your bet if you best your opponents. Here, you can throw killer punches and are also allowed to mix it up with flying kicks and witty submission moves that will knock out your opponents if they don't tap out!

On the flip side, if the classic charm of the Knockout Diamonds slots game is what made the slot a winner for you, you should take a shot at other titles in ELK Studio's Classic Series. One of the finest titles under that umbrella is the Hit it Hard slot machine which comes bursting with bonus items to enrich its nostalgic fruit machine ambiance.

Rumble on the Reels for Heavyweight Wins

What feature impressed you the most in this Knockout Diamonds slot review? Well, whether it's the Ringside Rumble, the Knockout Spins, or the Multiplier Wilds, you're indeed in for a treat on the reels from the first spin. The level of excitement here is high enough to make you forget that you are playing with only one payline!
