About Knockout Diamonds

Visuals and Sound

Graphics and Theme

Knockout Diamonds takes on a unique blend of boxing and classic slot symbols, creating a retro yet modern gaming environment. The game is designed to resemble a physical slot machine, complete with a boxing ring backdrop, adding to its charm​​​​.

Sound Effects

The game excels in its audio presentation, featuring sound effects that enhance the retro gaming experience. The background music and sound effects are reminiscent of traditional fruit machines, contributing to the overall vintage atmosphere​​​​.


Basic Mechanics

The game is presented in a straightforward format with a 3-reel grid and a single payline. This simplicity makes it accessible and enjoyable for both beginners and experienced players​​​​.

Bet Range and RTP

Players can place bets ranging from 25 p/c to $/€100 per spin, catering to a variety of budgets. The game’s RTP (Return to Player) is set at a competitive 96%, with a high volatility rating of 8 out of 10. Despite the high volatility, the hit rate is typical for slots of this type, standing at 12.8%​​​​.

Special Features

Ringside Rumble

This feature is triggered when identical symbols land on the first two reels, causing them to lock while the third reel respins three times. This increases the chances of landing a winning combination​​​​.

Multiplier Wilds

Multiplier Wilds can appear randomly, doubling or tripling the value of a line win. These wilds add an extra layer of excitement and potential for higher payouts​​​​.

Knockout Spins

The main highlight of Knockout Diamonds is the Knockout Spins feature, triggered by landing three bonus symbols on the payline. Players start with 3 free spins, which reset to 3 with any win or additional bonus symbol. Bonus symbols collected during this round are paid out according to a special paytable, with the potential to win up to 2,500 times the stake​​​​.


Knockout Diamonds stands out with its unique theme, engaging features, and solid winning potential. Its blend of retro charm and modern mechanics makes it an appealing choice for slot enthusiasts. The game offers a mix of simplicity and exciting features, suitable for players looking for straightforward gameplay with the potential for significant wins.

Final Thoughts

Knockout Diamonds is a well-crafted slot game that caters to fans of both retro slots and modern gameplay. Its unique theme, combined with special features like Ringside Rumble and Knockout Spins, provides an entertaining and potentially rewarding gaming experience.
