Overview Knockout Diamonds slot

Knockout Diamonds is the latest free slots no registration to be released by ELK Studios and the eight in their Classic Series of slot releases. This slot is a mash up of boxing and a classic fruit slot release and is played out using 3-reels and a single pay line, and whilst this does not sound a lot the slot packs some heavyweight features which includes the knockout spins and the ringside rumble feature. With some excellent prizes as high as 2,500x your stake. So, if you are ready to take on the knockout diamonds and rise to victory, keep reading.

Theme & Design

In the same way as the other ELK Studios’ Classic Series slots, Knockout Diamond has an old school feel regarding the design, and a boxing vs. classic fruit machine theme. The reels are set up in a vintage cabinet and although the theme is rather retro however the imagery is vibrant, slick, sharp and well put together.

Game Play & Statistics

Knockout Diamond plays out over a 3-reel, 1-pay line and when you land three or more of the same symbol or wilds on the pay line you create a win, and to be fair it does not get any simpler than that. When you are ready to play the first thing required is for you to choose the bet you are most comfortable playing with. There is a great bet range on offer starting from just 25p per spin up to a maximum of £100 per spin. There is also an auto play function where you can choose to play from 10 – 100 auto spins. You also have the choice of using the quick play function and whether you wish to play with or without sound, and these can both be changed to suit using the settings section of the game.

The return to player is set at a solid 96% which is about average when compared to other slots currently available and the hit frequency stands at 12.8% which means that theoretically you should land a win in every 8 spins, this does also mean that you will need to be patient with this game and sit back and wait.

You would be forgiven for thinking that this slot was highly volatile particularly as it has a boxing theme, however it is not as high as Mike Tyson was at his peak, but the slot can still give out a powerful punch. The developers have provided a volatility variance of 8 out of 10. The highest win you can expect from one spin is 2,500x your stake.


You can expect to see an assortment of classic fruit symbols on your reels which from lowest to highest are, cherries, single, double, and treble bars, lemons and lucky 7s. The highest paying symbol is the lucky 7 and this will reward you with 75x your stake when you land three on your pay line.

There is also a wild which is complete with multipliers and will reward you with 100x your stake if you land three in a combination, and the games logo is the symbol that activates the main bonus.
Finally, the slot can be played on all devices which is ideal if you want to be able to play the games wherever you are, and the visuals are so well done that they even transfer beautifully on the smallest of screens.

Bonus Features

When it comes to the bonus features there is a wide variety that can all provide you with a decent prize amount and include re-spins, multiplier wilds and free spins. First up is the multiplier wilds feature and as you would expect the wild substitutes for all the standard symbols to create winning combinations. The wild can also have either a 2x or 3x multipliers which can double or treble your wins. There is one exception and this the single and double cherry wins.
Next is the ringside rumble which is activated when you land the same symbols on your first and second reel. The symbols are then held and your third reel spins again three times which provides you with more chances to land the third the third matching symbol or wild to create a winning combination.

The final feature is the knockout spins feature and to activate this bonus you must land three or more of the knockout logo symbols on the pay line on the same spin. Once this is in play you are awarded with three free spins where your aim is to collect as many knockout spins symbols as you can. Every time you land one knock out symbol the free spins resets to three, and this symbol is added to the meter, and the more you collect the bigger prize Each time you do land 1, the number of free spins resets to 3. The symbol is then added to a meter. The more you collect, the bigger the prize awarded. If you collect three knockout spin symbols the reward is 5x your stake.

If you manage to collect ten of the knockout spin symbols you will be rewarded with the jackpot worth 2,500x your stake. The greatest reward is paid if you land three knockout symbols on the same free spins as this will pay 5x your stake, land four and you will win 10x your stake, land five and the prize is 25x your stake, 6 will reward you with 50x your stake, 7 knockout spins pays 100x your stake, 8 knockout spins pays 250x your stake, land 9 knockout spins and you will be rewarded with 500x your stake and if you land 10 knockout spins and you will win the highest reward which is a colossal 2,500x your stake.


In the same way as the other ELK Studios Classic Series Slot Knockout Diamond provides a retro theme coupled with a shard and vibrant design and some excellent features. The Knockout Spins feature reminds me of a streak re-spin bonus, and this can deliver some great action and if you get lucky and collect a good set of bonus symbols during the feature. The wild multiplier and re-spins also keep everything ticking along nicely. The high volatility and low hit rate mean that you can expect some long spells where your bank balance dwindles but hang on in there things do get better for those who wait.
