Knockout Diamonds Slot Review

Knockout Diamonds Slot Overview

Let’s get ready to rumble! Boxing spectacle and gladiatorial atmosphere meet classic fruit machine fun in this incredibly dramatic online slot game.  You are taken ringside to one of the biggest boxing matches of the year. However, instead of heavyweight champions, there is a nostalgic slot machine with a classic one-armed bandit feel. Created by ELK Studios, this game is played on a 3-reel, 1-row board with one crucial pay line.  To win combos, players must match the iconic symbols in matching formations across the board from left to right. Bonus features for Knockout Diamonds include a sticky re-spins feature, multipliers as well as a fixed jackpot. Bets for Knockout Diamonds range from 25p to £100 per spin. The maximum win for this smashing game is an awesome 2,500x your stake. Knockout Diamonds is a medium to high volatility slot game from the primetime boxing ring, with a return to player percentage of 96%.

Graphics and Theme

Knockout Diamonds feels almost timeless in its aesthetic because it combines two classic themes – nostalgic fruit machines and boxing.  The background is an arena-style boxing occasion with the ring placed at centre stage. Floodlights and blurred crowds give the player the impression of a large occasion, which adds to the momentous feel of the game. The board look like one of the classic reels sets you might find in any casino worth visiting. Symbols, like the rest of the theme, have been kept classic, from the cherries to the golden bell. When you enter the knockout spins round, your wins are displayed on an old-school laser light up board and accompanied by the boxers’ groans. ELK Studios have done all they can to persuade players that they are at a boxing match with the high-energy music and realistic boxing sound effects (including round announcements and bell rings).

Knockout Diamonds Slot Features

A variety of features are available for this Knockout of a slot game, including all of the classics from multipliers to free spins.

The wilds in Knockout Diamonds as in all slot games can substitute for all of the normal symbols, helping players forms more frequent wins. The wilds in this game sometimes come with an accompanying multiplier of either 2x or 3x your stake, helping to boost your per spin win takings. This works for all symbols bar the double and single cherry combinations.

One of the two main bonus games for this slot is called the Ringside Rumble Re-spins feature and is triggered when players land matching symbols on reels 1 and 2. These symbols are then stuck in place while the player gets three attempts to form more wins by spinning the final third reel. Landing matching symbols or a wild means big wins.

The next feature Is called the Knockout Spins feature and is activated when players land 3 Knockout Spins logo icons on the same spin. Once triggered, players will be granted three free spins to try their luck at winning bonus prizes. The goal here is to try and collect the greatest number of Knockout symbols once within the free spins game.

For every symbol that you land, your free spins are reset to 3, and the symbol that was landed is added to the meter above the board. The more of these symbols which you collect, the bigger the prize rewarded at the end of the feature. These multiplier prizes start at 5x your stake but can reach an unbelievable 2,500x your stake depending on the number of icons collected. To achieve the top payout, players must either collect 10 of these symbols from within the game or land three simultaneously on the reels. That is one knockout symbol on each reel on one spin.  The payouts for this feature are explained in the following bullet points:

  • 3 Knockout Spins symbols collected = 5x stake
  • 4 Knockout Spins symbols collected = 10 x stake
