Star Gems is what you’d expect based on that title, a slot machine where you get gemstones in space. It’s not the most imaginative idea we’ve seen chosen for the theme of a slot machine, but let’s see how Booongo implemented it and turned it into a game.

Released in late June 2018, Star Gems comes with a 5x3 reels game area, which is occupied by 10 fixed lines. Play it and you can win up to $2,500 from its best combinations, but there are several more advanced features as well, like its expanding wilds and re-spins.

Betting and Prizes

Just as it asks you to cover 10 active lines, the game will have a minimum bet of $0.20 that you can select. This means that the smallest amount that can go into a line bet is $0.02. As the maximum total bet allowed will get to $100, the highest line bet can obviously reach $10.

With its partially classic theme, the fact that it has a Red 7 for its main symbol shouldn’t come as a surprise. It’s going to pay $2,500 when it’s forming a full 5-symbol combo though, which is great. Have 10 lines of this type formed, for a top win of $25,000.

Star Gems Slot Features

If you go to the list of features that’s used in Star Gems, you might be disappointed with what you find there. The list has a single feature symbol, a Wild Four-Leaf Clover. This symbol is a replacement for any other symbol that it might be positioned to help, since there are no other features in the game. It’s an expanding wild as well, so if it happens to land on the reels on which it is allowed (2, 3 or 4), it will expand on them and take them over completely. At the same time, a re-spin will follow that expansion, and it’s going to be free.

The re-spin that occurs after the expansion of the wild will have the wild reel locked, so you get to re-spin only the other reels. You can get additional re-spins for the extra wilds that may appear and expand on the other reels. Those will also become locked for the re-spins that will follow. At most, the game mentions that it can give you 3 re-spins in a row. You can also trigger them again later though. Considering what it would be like to get the reels 2 to 4 filled with wilds, you can see that you’d have 10 lines occupied by winning combinations of at least 4 symbols each.

Theme & Design

They went with a gemstone theme in space, so you get the stars in the background image. The gemstones are part of some of the symbols used in this game, while in several high-paying positions you’re going to discover classic symbols. The theme is clearly not something that you’d expect to make you play this game for its sake alone. The design is reasonably well made, but we’ve seen 7s, Bar logos and gemstones way too many times to jump at the opportunity to play a game that has them.


Star Gems has one major feature around which it bases most of its gameplay, it has clean graphics but a boring theme. It’s not for everyone, but some players like this type of simple slot machine.
