Introduction
This game from the Endorphina demo slots catalogue asks you to follow in the shadow of the Northern Lights and see if you can uncover hidden treasures on 5 reels and 3 rows. The rarest gems are always the most precious and your aim is to land them on the 10 paylines of this jewel-inspired game. The makers try to help you by shining a light on the potential of the spins and offering two-way payouts, as well as a range of bonus features.
Gem Blast Theme and Story
This is a jewel themed slot based on a legend that centres around the Aurora Borealis, or Northern Lights. The idea was that a supernatural being unleashed the magical colours of the aurora into the sky, resulting in rare gems being left to be discovered - perhaps by you. If you like a game with a sparkling theme then you may also enjoy the Da Vinci Diamonds slot.
It is no surprise that gems take centre stage in this slot. Even the standard 7s and Bars have been given a sparkling upgrade. Meanwhile, the background is created to look like the Northern Lights, although it would have been nice to have seen a bit more detail, such as some landscape or other features.

Gem Blast RTP and Variance
This game islow to medium variance and has a theoretical return to player average of 96%. If you decide to play the gamble feature, you will encounter an average RTP of 84%. The gamble feature can increase substantially based on the dealer’s card and this is explained in more detail on the slot’s paytable.
How to Play Gem Blast
The gameplay is clear enough but there are a few hints that you might benefit from when you start to play:
- The dollar sign is what you need to click on to set your bet and choose how many of the 10 available lines you want to play.
- The i symbol is where you will find the game’s paytable.
- Click on the 3-line menu tab for a range of options. This is where you can set the autoplay function, change the sound settings, choose your language and view game history statistics.
- If you choose to play the game’s gamble feature after a win, you will need to choose a card that is higher than the dealer’s. If you don’t, you will lose your win. You can choose to collect your win after each round. No card can beat the joker and only you can draw one of these. You will tie and live to fight another day if your card is of equal value to the joker. If it’s lower, you will leave with nothing.
Gem Blast Paytable Wins
Most online slots only pay out for wins that go from left to right but this game features a win-both-ways mechanism. This means that you can also line up winning combinations from right to left. The maximum wins on offer for 5-strong combinations are:
7s - 10,000
Bars - 5,000
Orange gem - 2,000
Yellow gem - 2,000
Green gem - 1,500
Aquamarine gem - 1,500
Blue gem - 1,000
Purple gem - 1,000
The prizes displayed in the game’s paytable depend on how much you choose to bet. On each spin, you get to decide how many of the 10 lines you want to play, how much you want your coin value to be, and how much you want to bet. The minimum you can bet is 0.01 coin value, 0.01 bet and one line. This means your minimum bet would be 0.01, or 1.00 credits. The maximum you can bet is 10 lines with a coin value of 1.00 and a bet of 0.10. This translates into a maximum stake of 100.00. This is a fairly decent range, offering a good option for cautious spinners and a reasonable upper limit for spinners who like a little higher rolling action every now and again.
Gem Blast Bonus Features
The Win Both Ways mechanism is the major feature of this game but it is not the only bonus on offer. The Diamond Star is the wild of the game, offering the chance to replace other symbols in order to make wins. In this slot, the wild can also expand to cover reels and will also trigger a respin. It can cover reels 2, 3 and 4 and could, therefore, lead to 3 respins from a single spin.
Gem Blast has a gamble feature after each win - if you are feeling lucky and want the chance to increase your prize. This is a typical risk game where you have to beat the dealer in a pick ‘em challenge. You could, potentially, boost your win by as much as 10 times by picking right and doubling your prize in each available round but remember, you will lose your whole prize if you don’t choose the right card.
Gem Blast Review
This is an entertaining enough game but may not be exciting enough over long periods if you are used to a bevy of bonus features in your slot. There are wilds, expanding wilds and respins, along with a risk game, but this will always be a better choice for traditional slots fans rather than for those looking for innovation and additional excitement features.
