Introduction
Northern Heat is an attractive 40-payline slot that plays out on a 5x4 grid, making it ideal for mobile play.
Mascot Games have added the innovative Infinite Free Spins feature to this slot, so look out for the compass scatter symbol. Just two scatters will trigger this high-potential feature.
Balancing things up is the paw print wild that replaces any symbol except the scatter for more potential wins across multiple paylines.
The objective in this 10 paytable symbol slot is to land identical symbols on one of the 40 paylines to earn a payout. The symbols aren’t particularly high-paying, but if the Infinite Spins with wild reels kick in, some big wins could be snowing down on you.
Even though this slot is playable from as little as 0.40 credits, we recommend you play a few demo mode spins so you can try before you play for real money. Mobile spins are flawless no matter what device you prefer.
Theme, Graphics & Soundtrack
If you’ve played free Mascot Games slots, you’ll be aware of their audiovisual prowess. And if the design is sometimes unsuccessful thanks to a reliance on royals, this game manages to create a fully immersive world thanks to the combination of soundtrack and graphics.
The reels give the impression that they’re set in a hole in the ice or on a frosted windowpane surrounded by delicate fronds of ice. The glacial blue and white colour palette is equally appealing, and the sound effects conjure up a land of snow and ice.
The picture symbols are all arctic animals, including the snowy white fox, majestic polar bear, adorable baby seal and distinguished walrus. They’re richly detailed and presented in a photo-realistic way.
Play this slot on a warm day and you’ll instantly feel cool as a cucumber.
RTP & Volatility
This medium-volatility slot will have a broad appeal for new players and experienced ones. The above average RTP of 96.9% is another attractive feature.
How to Play Northern Heat
Northern Heat is an enjoyable slot, but you should always protect your bankroll by setting a session budget that lets you enjoy your games responsibly.
The pared-back mobile-friendly interface makes set-up a breeze.
1. Start by taking a look at the paytable information by tapping the menu symbol on the bottom left.
2. This menu also lets you speed up your spins, play in full screen or mute game sounds.
3. Autoplay is manually controlled - simply tap to start and stop your autoplay games.
4. Use the plus and minus buttons to set your stake or use Max Bet to go all in.
5. Hit the paw print spin button to play your game.
Min & Max Bets + Top Wins
To find your ideal stake use the player-friendly interface to select a bet from just 0.40 to 40.00 credits per spin. The Max Bet option is the one-click way to play at the maximum stake. It’s impossible to know what the top win in this slot could be with the indefinite Infinite Spins feature and wild reels, but the feature itself is highly volatile. A screen full of Arctic Fox symbols would pay 1000x your stake.
Diving deeper into the paytable we find upper and lower symbols which pay in multipliers of your stake as follows:
- Arctic fox pays 25x
- Polar bear pays 12.5x
- Baby seal pays 10x
- Walrus pays 10x
- J-A pay 2.5x
- 9 & 10 pay 1.8x
Infinite Free Spins Feature
We know that bonus features can sometimes be difficult to get to grips with. That’s why we take a closer look at the special symbols and bonuses so you can play with confidence. This slot is all about the Infinite Free Spins feature.
Wild Symbol
The wild symbol appears on reels 2, 3 and 4 in the free spins and base game and substitutes for all symbols except the compass scatter.
Scatter Symbols
The compass scatter appears in the main game and free spins on reels 1 and 5 only.
Two scatter symbols in the base game trigger the Infinite Free Spins.
Infinite Free Spins
Free spins continue until two scatters land on reels 1 and 5.
Wild symbols become expanding wilds, creating wild reels where the symbol is stacked to the height of the reels.
Wilds substitute for every symbol except the scatter.
