Sydney-based slot developer Lightning Box Games has launched its latest title Viking Fire, with Swedish gaming operator Betsson gaining exclusive access to the game for an initial period.

The game is a 4x5-reel, 40-line slot featuring a bonus game in which players are challenged to catapult rocks at enemy longships to earn up to four extra wilds and eight free spins.

"Viking Fire is a light-hearted take on the traditional Norse theme, and combines colourful graphics with a catchy soundtrack and engaging math model," said Peter Causley, managing director and co-founder of Lightning Box.

Designed in HTML5 for desktop and mobile, the launch of Viking Fire follows the roll out of Stellar Jackpots-Chilli Gold x2 in the UK with operators bet365, Coral and Mr Green.

Lightning Box supplies video slots for the land-based, online and mobile gaming sectors, with its games currently available via the NYX and GECO Gaming Remote Games Services. The developer is also in the process of rolling out its content for Everi Holdings and Ainsworth Game Technology in the coming months.

The game will go on general release for all partners from November 30th following its exclusive launch via Betsson-operated sites.

"We are delighted to be offering the game exclusively to Betsson for two weeks before rolling out Viking Fire on general release," Causley added. "I'm sure their players will be more than ready to become one of the Vikings and take out the enemy ships to win big prizes."

Paul Malt, head of games at Betsson, added: "We are always looking for new games to bolster our already impressive portfolio, and Viking Fire certainly fits the bill. The bonus game feature is particularly exciting, and we are sure our players will have fun trying to take out the enemy ships."
