Stellar Jackpot Dolphin Gold, the latest release from slot design specialist Lightning Box Games, has made a splash in Europe after launching exclusively with BetVictor before going on general release.

The 4×5 reel, 40-line video slot combines oceanic and intergalactic themes, and boasts a unique bonus trigger involving up to 12 stacked wilds. Six blue dolphins trigger the Gold Dolphin free spin bonus, offering three free spins while 12 blue dolphins offer 21 free games.

It also features Lightning Box Games’ innovative Stellar Jackpot bonus that is launched from a random hidden trigger in the game. Players are taken to a space shooting arcade game for the chance to win epic prizes.

The game has been developed in HTML5 and offers smooth graphics and intelligent maths with which to engage players. It is available across desktop and mobile devices, iOS and Android.

Stellar Jackpot Dolphin Gold is available exclusively to BetVictor players for the next week before going on general release to other operators.

Peter Causley, managing director and co-founder of Lightning Box Games, said: “Stellar Jackpot Dolphin Gold combines the smart math and fun theme of the already proven Dolphin Gold, and then adds something a little bit different in our innovative Stellar Jackpot bonus game, where players can win major prizes.

“We are thrilled to have launched the game exclusively with BetVictor, and look forward to receiving feedback from their players before we push it out to the rest of the market.”

Arcangelo Lonoce at BetVictor, said: “Stellar Jackpot Dolphin Gold is an awesome game with a quirky theme that will stand out in our portfolio for all the right reasons. The math behind the slot is excellent, and offers an exciting and engaging player experience.

“We are delighted to be able to offer the game to our players ahead of our rivals, and believe it will quickly become a smash hit on both desktop and mobile.”

Lightning Box Games recently struck a trio of deals with online casino operators in the UK, with its Silver Lion title launching simultaneously on Coral, Unibet and Betsson.

Its blockbuster land-based hit Astro Cat also launched exclusively with Mr Green back in October before being rolled out to the wider market.
