Doctor Electro is the latest slot from developer Kalamba Games, released exclusively via Relax Gaming‘s Silver Bullet program.


Out now.


“Kalamba Games’ latest slot Doctor Electro amps up the excitement with an expanding reel offering players the chance to unlock electrifying wins.”


Starring the eccentric character Doctor Electro, the game sees the return of the player-favourite HyperBonus feature, which presents slot fans with a shortcut to free-spins rounds, as well as two levels of bonus jackpots.

Players collect column expansion symbols to trigger the all new HyperSpins feature that reveals expanding reels and increases the win potential.

The game is a five-column, four-row base game, increasing to seven rows and up to 16,807-way pays.

Doctor Electro is exclusively distributed on the Relax Gaming platform via its Silver Bullet partner program and is available to leading casino operators.


“Doctor Electro introduces a unique layer of player engagement with column expansion collection and our new HyperSpins feature.

“The game also has fantastic artwork, animation and sounds, and together with our proven engagement, monetisation and retention features, we are confident Doctor Electro will get players buzzing with excitement,” – Alex Cohen, Kalamba  COO and co-founder
