Babushkas is a 5 reel, 17 fixed payline slot which is brought to you by Thunderkick. Playable from 10p to £100 per spin across desktop, mobile and tablet devices, it has a Russian doll theme and features wilds, 4 symbol upgrade features and a bonus feature of free spins with guaranteed wilds.

Theme wise, Babushkas is a little unusual (like other Thunderkick slots!) – it’s based on those Russian dolls (also known as matryoshka dolls) which decrease in size and are placed one insider another. Colourful and featuring 7 dolls, the more you pop, the more they rock. All symbols have a number associated with them ranging from 0 to 6.

Highly entertaining, Babushkas features bears – they will charm, scare and dance with you and do everything they can to get your dress off. The less clothes, the better the rewards. In terms of symbols, look out for the wild egg symbol which can appear on the middle reel – when a star is revealed, it may randomly trigger 1of 3 Bear Mystery features.

You have the Scare Bear feature – all of the lowest value symbol on the reels will be upgraded. This may happen up to 3 times, depending on the size of the bear, meaning your wins can be seriously enhanced.

Then there is the Charm Bear feature where all symbols on the reels will be upgraded by 1 level once only. Finally, there’s the Dance Bear with rewards you with 7 free spins. During the feature, a new wild egg will appear on reel 3 for each free spin – this gives you the chance to trigger 1 of the 3 Bear features!

Now, if you manage to get 15 symbols all the same on the reels once all win symbol upgrades have taken place, they will upgrade once more – this is known as a Wipe win. If this applies to the highest value symbol, you will win a special wipe win prize which is 100 times your stake.

The aim in Babushkas is to fill the screen with the top valued symbol – you can start by getting that first win and watch the dolls start upgrading. With some luck and help from the Bear, the upgrades can start and hopefully you will land that ultimate Wipe win. As mentioned, the more you pop, the more they rock and the bigger your wins.

There’s a cool 390 times your stake to be won on every single spin so plenty of potential – Babushkas may sound complicated but it’s rather simple once you get spinning. I do love the concept as it’s completely unique and nothing like I’ve seen before.

Variance wise it’s in the low to medium bracket so it should provide a lot of entertainment for your time. If you like innovative concepts, Thunderkick offers you this in abundance with Esqueleto Explosivo and 1429 Uncharted Seas highly recommended.
