Gem Burst is a 5 reel, 243 ways to win slot from Playtech that can be played from 25p to £500 a spin – across all devices of course. With a space/meteor feel to it, it comes with cascading wins that can give you consecutive wins with the multiplier reaching up to 5x. There’s also a Blasting Free Games feature where you can play with up to 30 free spins

You are taken to what looks like Planet Kryptonite in Gem Burst – with a space/futuristic theme, it’s all about bursting rocks. You have rock-like A, K, Q and J symbols are well as 4 different types of rocks. The red one is the most lucrative gives you 20 times your stake for 5 across a payline. There is also a wild rock symbol which replaces all symbols bar the 2 scatter symbols.

With 243 ways to win, you can form winning combos when you land 3 or more symbols in adjacent reels beginning from reel 1. Like Legend of the Jaguar, it uses the Win Cascades and Multipliers features – when you get a win, the contributing rocks burst to make way for new falling rocks. Each cascade increases the multiplier from 1x to 2x to 3x to 4x and finally 5x. This means you can win time and time again from each spin.

Gem Burst comes with a Blasting Free Games feature which is played when you get 3 or more dynamite scatter symbols anywhere on the reels – every scatter can turn into up to 3 Blasting Free Games bombs with each of them awarding 2 free spins. Therefore, you can begin with between 6 and 30 free spins.

Before the free spins begin, you choose where to place them – you place them below a reel by dragging them from the reel area. You’re allows up to 3 Blasting Free Games bombs under every reel. Look out for the Mystery symbol on the reels – when it appears on a reel where a Blasting Free Games bomb is placed, it detonates and explodes the Mystery symbols to give you an instant cash bonus.

Furthermore, the amount of Blasting Free Games bombs under a reel acts as a win multiplier for the Mystery symbol winnings – if you were to have 3 Blasting Free Games bomb under a reel, you instant cash bonus will be subject to a 3x multiplier.

Now, Mystery symbols on the first 3 reels are worth less than on reels 4 and 5 as it’s easier to form winning cascades on the first 3 reels naturally. That means it’s would be more beneficial, in theory, to place more bombs on reels 4 and 5 for bigger wins. You could always put them on reels 1, 2 and 3 to play it safer – the choice is yours.

I found Gem Burst to be entertaining and more rewarding than first thought – I found it to be a medium variance slot with maximum payouts of 2,500 times your stake on each spin (500 times stake with a 5x cascade multiplier). You can win bigger than this with the Mystery symbols in the feature due to the cash prizes. Overall, a good slot from Playtech – if you like cascading slots, Play ‘N Go’s Viking Runecraft is a superb option.
