A winter slot with a polar-bear host
Northern Boom is Belatra's winter-themed online slot. Its official description places the action in a permanently frosty and sunny setting, where winter entertainment is joined by local animals and a large polar bear as the game's charismatic central character. The provider presents the game as bright, colourful and varied, but does not publish a full story sequence or a complete list of the symbols used on the reels.
The published game profile lists 95.25% RTP, medium volatility and a stated maximum win of 4000x. RTP is a theoretical long-term return figure, while volatility describes the stated payout profile rather than the result of an individual round. The maximum win is the provider's published upper payout limit. Paylines, symbol values, bet range and the full paytable should be checked in the active game.
Free Games and the super symbol
Northern Boom includes Free Games. The provider highlights a large super symbol during this feature: it covers reels two, three and four and substitutes for nine regular symbols. This is the confirmed role and reel coverage of the super symbol, making it a central part of the published Free Games description.
The source does not state the trigger for Free Games, their starting number, retrigger rules, multiplier values or the exact conditions under which the super symbol appears. It also does not identify the nine regular symbols individually. Opening the game lets a player inspect the current feature rules and see how the large symbol behaves in the live reel layout.
Hold-and-Win Bonus and jackpots
The slot also has a Hold-and-Win Bonus built around three respins. During those respins, the player has an additional chance to land one of three listed jackpots: Grand, Midi or Mini. The possible symbols named by the provider are credit symbols, jackpot symbols and empty symbols. The published objective of the feature is to land the Mega Jackpot symbol for its prize.
Belatra also mentions risk games among Northern Boom's additional games, without setting out their individual rules in the available description. The confirmed bonus information supports a clear picture of the Free Games super symbol, the three-respin Hold-and-Win structure and the listed jackpot categories, but it does not guarantee a payout in any session. Use the demo to examine the winter presentation and the active rules before playing.
