Knockout Diamonds Online Slot Review

Although this looks like a very basic 3-reel, 1-line game, the Knockout Diamonds slot punches above its weight, with a variety of exciting bonuses available at the top New Jersey online casinos or the best Pennsylvania online casinos. The reels sit against the backdrop of a boxing ring, lit up and ready for the big fight, and the developer, ELK Studios, has even added a Rocky-style soundtrack and voice of a compere to help create the atmosphere.

The symbols are pretty standard, with cherries, BARs. Bells, and red 7s joining the game logo on the reels. Like many 3-reel slots, the paytable sits above the game, making it easy to see how much you can win each time you land 3 examples of the same symbol across the line. Wild symbols help out, and these can even multiply winnings, while a respins feature gives you a second chance to collect a prize. Enter the Knockout Spins round and you can win up to 2,500x your bet.

It’s a simple, but highly effective setup that looks good on PCs, and the portrait orientation of the main game is a perfect fit for iOS, Android, and Windows mobile screens at any of our recommended mobile casinos, including when you use a no deposit bonus.

How to Play the Knockout Diamonds Slots Game

To select a bet level, click the button that looks like a pile of coins. This opens up the various options that run from a minimum of 0.25 to maximum of 100.00 per spin. This generous bet range makes it a game that appeals to many players, and it’s so easy to set up that even someone with no experience can get started in seconds.

Press the 3 short lines at the top of the game to see how the various features, such as the Ringside Rumble Respins play out, and look above the reels to you see how many times your bet you can win from each symbol. The Wild pays the most, returning 100x your stake when you see 3 on the line.

Respins & Other Knockout Diamonds Slot Features.

Wild symbols not only pay the highest prizes, but also act as others if they can complete a win. Some wilds come with 2x or 3x multipliers attached to them, which boosts any win by the corresponding amount. (Although a 250,000.00 maximum payout still applies.)

The Ringside Rumble Respins trigger when you land matching symbols on reels 1 and 2. Reel 3 respins 3 times, to give you a chance to complete a combination.

The game logo symbol right across the payline will launch the Knockout Spins feature. You get an initial 3 free spins, with any further logos symbols resetting the counter back to 3 games, and collecting in a meter above the reels. The feature runs until you have 3 spins with no new game logos appearing, after which, you collect a prize, or you fill the meter to collect the 2,500x jackpot.

Maximum Wins, RTP, & Volatility of Knockout Diamonds Slot

The 2,500x your stake jackpot is the most you can win from the Knockout Diamonds slot machine. Play with 100.00 on the triggering spin to claim a prize of 250,000.00. This is a medium to high volatility slot and on average, it pays back at 96%.

Our Knockout Diamonds Slot Rating

Don’t be put off by the 3-reel, 1-line layout, as this is a game that delivers a hefty punch from the various bonus rounds. The respins feature can often create a win from a losing spin, and wild multipliers can give your bankroll a real boost.

However, it’s in the Knockout Spins feature that the game really shines. A win is guaranteed from the triggering symbols, and if you collect more game logos during the spins, the payouts rise with each. You’ll need a total of 10 symbols to claim the title which isn’t easy, but certainly not impossible either.

Play the Knockout Diamonds slots game at our recommended Pennsylvania slots sites and the top New Jersey slots sites carrying the ELK Studios Range. We’ve found the ones with the biggest and best welcome bonus deals, and feature them right here.
