Gem Star Slot Machine

Head into outer space with this intergalactic slot from Amatic, themed on a mysterious combination of space travel, fruit machine symbols and precious gems.

The symbols in the game are all colourful precious stones, lucky sevens and bar signs, while the background transports players into deep space. There are various other exciting features in the game, including 100 paylines, wild symbols and re-spins.

This is a simple game with an interesting combination of themes and will appeal to space fans looking for lots of different ways to win while playing a colourful slot game.

Before You Blast off...

Before starting your intergalactic adventure, have a look at the betting options and select your stake. There are an impressive 100 paylines in this game, potentially offering lots of winning chances every spin. The paylines are not fixed, which means you can select how many or how few of them you would like to play, in increments of 10. You can also change your bet per line by clicking on the ‘bet’ button at the bottom of the screen to move from 1 to 50 credits per line. This gives an overall bet per spin of 10 credits to 5,000 credits.

Altering the bet per spin is not an easy task as there is no minus button to take your bet down. If you want to move your bet lower you have to go up through all the bets to the highest bet until you can access the lowest bet again – and just be careful not to overshoot or else you will have to go round again! This bad design sometimes makes changing your bet a troublesome task.

The space theme mingles with the precious gems and the fruit machine symbols to give an eclectic feel to the game. The symbols include a red lucky seven orbiting a planet, a purple bar sign, a colourful wild star, an amber stone, and ruby, emerald, sapphire and amethyst stones. There is no music here to bring the space theme to life with only some twinkling sound effects to congratulate a winning combination.

Payouts in Outer Space

The payouts in this slot are decent if not amazing, with the highest-paying symbol the red seven which pays 25,000 credits for 5 matching symbols when playing max bet. The next highest-paying symbols to look out for is the purple bar sign which awards 12,500 credits for 5 matching symbols at max bet. The amber and ruby gems are not far behind with 10,000 credits available when you spin 5 of these symbols together while playing max bet. The lower paying icons are the sapphire and amethyst gems which both pay 5,000 credits for 5 symbols at max bet, and the emerald which pays 2,000 credits for 5 symbols at max bet.

Starlit Re-Spins

The multi-coloured star symbol is the wild in this game. This means it stands in for all the other symbols to create more potential winning combinations. Whenever 3 of these symbols appear together, the re-spin feature begins to give you 1 re-spin. During this re-spin, the wild star reel holds in position. This feature is re-triggerable from within the round, so if you spin more wilds, you could activate even more re-spins. If you hit 3 stars on all 5 reels, the feature comes to an end.

Plenty of Potential Payouts - but Not a Shining Star

The mixed space and gem themes of this slot might seem a little at odds with each other, but they come together well to create an entertaining game with plenty of wining potential. Most players will be able to enjoy this game whatever their bankroll as it has a wide betting range, while the colourful gems, familiar fruit machine symbols and intergalactic flavour will have something to appeal to everyone. The lack of music is a lost opportunity as this could have helped to spice up the feel of the game, but the basic sound effects do help to add some atmosphere.

Overall, there are a decent number of ways to win here thanks to the 100 paylines and the regular re-spins available from the multi-coloured wild symbol. Players looking for a simple game with bright graphics and large number of paylines will enjoy playing Gem Star but the lack of other special features means this slot game will probably never become a star.
