Polar Slots

Grab your gloves, slip on your scarf, and wrap up warm. It's time to go sub-zero with Polar Slots by Mr Spin, an arctic adventure and quite literally the coolest game in our mobile casino! It’s chillier than an eskimo’s piggy bank, but even more bulky.

Polar Slots features nine frozen win lines, a marvelous mini-game where you can win mega money, and a huge progressive Jackpot that’s big enough to sink the Titanic. It's time to brave the cold and jump right into this mobile slots adventure!

Getting Started

You’ll be feeling ice cold with Polar Slots in no time, as getting started is as simple as adjusting your bet amount and number of win lines by using the ‘+’ and ‘-‘ symbols. Once you’ve got a total bet amount – which is calculated by multiplying your bet amount by the number of win lines you’re playing across – you’re cool with simply tap ‘Spin’ to start playing.

We won’t give you the cold shoulder, you can adjust your bet amount and number of win lines any which way so that you get a total bet amount that you’re happy with. As an example, you could bet 10p across all 9 lines for a total bet amount of 90p, or you could bet £1 across 5 lines for a total bet amount of £5.

Bets start from a brrr-illiantly low 2p and freeze up to a total of £20 a line.

If you’re worried about losing your fingers to frostbite, you can keep your hands free by using Polar Slots’ ‘Auto Spin’ feature. Simply set a number of spins, credit limit, or maximum win, tap ‘Start’ and you’ll be having a whale of a time as the reels roll in automatically.

Want to freeze the ‘Auto Spin’ process? Simply tap ‘Stop’ and you’ll revert to the game reels for normal play.

How to Play

After you’ve fin-ished adjusting your total bet amount, tap ‘Spin’ and our frozen reels will roll in and stop at random.

Wins sled in from the left, meaning all winning combinations on win lines pay left to right. What constitutes as a pengwin depends on the type of symbols you’re freezing in a line. Some wins require just 2 or more symbols on an active win line, while others require 3 or more on an active win line.

There’ll be snow confusion when you roll in a win, as all wins across an active line are highlighted, before winnings are added to your account balance.

Reel Wins

Wins are calculated by multiplying your bet per line. If you want to see just how much each winning combination is worth, skate on over to the Polar Slots’ paytable. There you’ll find all information about win values, winning combinations, and how win lines are laid out.

We don’t want to give you a frosty reception, so we’ll combine any wins across different win lines to give you a higher total win, however only the biggest win from each individual win line can be counted.

Wild Symbols

You’ll be feeling the polar opposite of blue if you see a Wild symbol in the correct position on an active win line, as it can swap out for any other symbol to make up a win. For example if you had two As on an active win line next to a Wild symbol you’ll get a win equivalent to rolling in three A symbols.

Wild symbols cannot be substituted to make up a mini-game or Free Spins win and the progressive Jackpot cannot be sealed with a Wild symbol on the winning line.


Will you p-p-p-pick up a prize in the Polar Slots mini-game, Penguin Dash? Line up two or more mini-game symbols on an active win line to reach an icy island, full of cracking multipliers. Press ‘Roll’ to move your penguin pal across the board, picking up multipliers as he goes.

The aim of the game is to collect as many prizes as possible! Reach the golden fish on the trail for a mega multiplier! You keep every prize you land on – meaning your prize pot grows and the penguin goes – but land on the fish bones, and the mini-game ends.

Bonus Free Spins

You’ll be soaring if you line up three or more seagull Free Spin symbols on an active win line, as you’ll be spinning on Mr Spin!

3 Free Spin symbols grant 5 free spins, 4 will bag you 7 free spins, and 5 will get you 9 spins on the house. Free spin are frozen to the value of your last spin.

Progressive Jackpot

The occurrence of 5 (five) “JACKPOT” Jackpot symbols on an active win line awards a progressive Jackpot. The progressive Jackpot is available on any bet, with 0.005% of the bet being added to the progressive pot. There is no hidden reserve pot.

When the Jackpot is won, it is reset and begins to rise again. Simultaneous wins can occur, if another player wins the progressive Jackpot then a notification to this effect would occur BEFORE the current player was awarded the Jackpot.

In the event of a communication error after a progressive win result has been determined and before it has been displayed on screen, the win amount will automatically be transferred to the player’s account. While the game is live, the Jackpots cannot be terminated.
