Rules and Gameplay

The essence of Knockout Diamonds lies in its simplicity merged with the thrill of boxing. This slot game, developed by ELK Studios, is played on a 3-reel setup with a single, central payline. Bets can be placed within a range of $0.25 to $100 per spin, catering to both casual players and high rollers. The game masterfully combines the charm of vintage slot machines with the excitement of a boxing match, offering a unique gaming experience without actual combat in the ring.

Bonus Features

Knockout Diamonds offers a robust suite of bonus features designed to enhance the gameplay and increase winning potential:

  • Ringside Rumble Respins: Activated when identical symbols appear on the first two reels, locking them in place for three additional respins on the third reel.
  • Multiplier Wilds: Wild symbols can boost payouts by 2x or 3x when they substitute in a winning combination.
  • Knockout Spins: This feature kicks off when three bonus symbols land on the payline, offering free spins that can reset and accumulate bonus symbols for jackpot rewards.


The game’s symbols reflect its classic slot heritage and boxing theme:

  • Standard Symbols: Includes cherries, bars (single, double, triple), bells, and lucky 7s.
  • High-Value Symbol: The wild symbol, which not only substitutes for other symbols to create winning combinations but also carries the highest payout multiplier.


Payouts in Knockout Diamonds are designed to reward players handsomely, with a focus on the collection of bonus symbols during the Knockout Spins feature:

Bonus Symbols Collected Payout (times stake)

Despite its elaborate features, Knockout Diamonds remains faithful to the classic slot formula with a single payline. This streamlined approach not only nods to traditional slot machines but also makes it straightforward for players to follow along and understand how wins are formed, ensuring that the focus remains on the excitement of the spin.
