Our Verdict of Star Gems Slot

Star Gems is a 5-reel slot with three rows of symbols and 10 paylines that pay both ways. It has expanding wilds that trigger free respins for the chance to improve the payout further. In this regard, it is very similar to NetEnt’s iconic slot Starburst.

However, the style and theme are slightly different, incorporating a more cartoonish design and even including a green alien. Moreover, the Star Gems slot machine has three progressive jackpots, which are shared across multiple slots on the Fazi network. These add a bit more excitement as players can hit the motherload on any spin.

While it doesn’t have the most original concept, the five spinning reels can be quite entertaining. The game has low-medium volatility with a good hit rate, so you will win as you go. We would have liked to see a free spins mode or a bonus game for even more opportunities to cash in big though.

What we like:

  • 10 lines with Win Both Ways feature
  • Simple gameplay with constant wins
  • Expanding wilds on reels 2, 3, and 4
  • 50/50 gamble game available after win

What we don’t:

  • Not the best mobile optimization
  • Doesn’t have a free spins mode

How to Play the Star Gems Slot

The dashboard under the five reels makes it very easy to play Star Gems online. Everything is easily accessible and it only takes a few clicks to set everything up. So, if you want to play Star Gems slots, just follow these steps:

1. Load the Game Online

Star Gems is an HTML5-based online slots game that will load directly on the browser. So, all you have to do is click on the game at your preferred online casino. It will load in just a few seconds.

Fazi Loading Screen

2. Set the Total Bet per Spin

You can activate up to 10 paylines in the Star Gems slot. The minimum bet per line is $0.20 and the maximum can go up to $5,000. However, the precise min/max amount can depend on the online casino. We recommend using all 10 lines at an affordable level.

3. Start a Round

After setting the bet, click on the “Start” button to play one round. You can also activate the auto-play function for up to 1,000 consecutive spins or set preferred limits.

4. Take, Win, or Gamble

When landing a winning combination, you can take the payout or enter the gamble mini-game. If you choose the latter, you are using the win amount in a 50/50 game where you guess the color of a random card. Guess correctly and you double the amount.

Star Gems Slot Gamble Game

5. Repeat

If you land a wild symbol, it will automatically expand and trigger a free respin with the respective reel being completely wild. Once the round is over, you can change the bet or continue playing at the same stake.

Star Gems Slot Paytable

As with most online slots, payouts are only granted for combinations of symbols that start from the leftmost reel. However, the paylines in the Star Gems slots game pay both ways, which allows for more opportunities to win.

You will need to match three or more identical symbols on the same active line to win. These symbols also need to be in adjacent positions, either from left to right or from right to left. The wild symbol shows a mix of gems of different colors and it expands to take over the reel. Wilds substitute for any other symbols needed for a win.

More symbols in a combo offer a bigger win and rare symbols also pay better. The following paytable has the payouts based on the bet per line:


3 Symbols

4 Symbols

5 Symbols

Golden Disk




Ruby 7




Yellow Gem




Green Gem




Red Gem




Blue Gem




Purple Gem




Star Gems Paylines

Players can activate between 1 and 10 paylines in Star Gems. These follow set patterns across the 5×3 grid on the screen. While having only 10 lines is not ideal, these pay both ways, and so they allow for somewhat frequent wins. Only one combination counts per line, so 5 matching symbols on the same line pay only once.

Star Gems Slot Bonus Rounds & Free Spins

Star Gems doesn’t have an actual bonus round or a free spins mode. Instead, the bonus feature is the wild respin. When a wild symbol appears on the screen, it expands to take over the entire reel. It then keeps its position for a free spin for the chance to win more.

Star Gems Slot Respin Feature

Another bonus feature worth mentioning is represented by the three progressive jackpots. The developer behind the Star Gems slot, Fazi Interactive, has a progressive jackpot network with three prizes. These increase when players bet on the eligible games.

You can win any of the jackpots randomly on any spin. They don’t require a set combination or bonus game. However, the higher the bet, the better the chances are of hitting a jackpot when playing the real money Star Gems slot.

Star Gems Slot Gameplay

The Star Gems gameplay is smooth since it isn’t interrupted by various bonus features. The wild reel respins keep the same overall pace. There are also some issues as the slots game doesn’t have a quick-spin feature and so players need to hit the stop button for faster rounds.

RTP & Volatility

With a theoretical return-to-player rate of 96%, the Star Gems slot machine promises good overall returns. It matches other popular slots, like The Vault, and is only a bit behind Starburst, which has an RTP of 96.09%.

More importantly, the low-medium volatility makes it a good choice for shorter sessions. It has a hit frequency of 3.99, so you will land winning combinations every few spins. Moreover, the payouts are substantial since symbols can appear stacked on all reels.


Star Gems is an online slots game developed by Fazi Interactive. The software developer is based in Serbia and mostly caters to the Balkan area. It boasts a massive portfolio of over 110 online casino games, focusing mostly on slots but also including virtual table games, video poker, and dice games.

Now that we know who makes Star Gems slots, what other games from the developer are popular online? Many of the options have classic slot themes, with fruits, sevens, and gold bells. We recommend checking out Giga Hot 40, Lolla’s World, and Book of Spells Deluxe.

Graphics & Sound

The graphics in the Star Gems online slot are pretty good. While it doesn’t offer the latest in 3D animations, it also doesn’t disappoint with its visuals. The symbols are quite basic but the different colors and shapes make them easily distinguishable. They show small animations to highlight icons when forming winning combinations.

As for the sounds, Star Gems comes with a mix of traditional slot machine noises and futuristic effects. It can be a bit weird to hear coins dropping and high-powered lasers in the same round. Although they can get repetitive after a while, we enjoyed the sounds for short gaming sessions.


The Star Gems slot theme is represented mostly by the background image. Here, we see that the action takes place on a different planet. A little green alien in a robot suit is in charge of mining the rare gems and he lights up when a winning combination forms.

Other than that, the symbols show gems of different colors, and the wild combines several of them. It isn’t the most intricate slot theme we’ve come across but it is better than your standard fruit machine.

Our Top Star Gems Slot Tips

Star Gems is a fun slots game that comes with some notable mechanics. The following tips will help you make the most out of the spinning reels. Learn how to win on Star Gems right here:

star gems slot tips

1. Make Sure to Practice for Free

As it is with any new casino game, it is best to practice for free before betting real money. Luckily, Star Gems is available in demo mode and you can check it out without spending any cash. You have a bankroll of $5,000 to work with and you can always refresh the page.

2. Play All 10 Paylines

Make the most out of the bonus feature by playing the maximum number of lines for every bet. The wild reels with free respins represent a great source of big prizes and it is best to have all 10 lines active. You can activate them from the dashboard at the bottom of the screen.

3. Don’t Be Afraid to Bet Big

The size of the bet is very important and it depends on the type of game you are playing. Since Star Gems has low-medium volatility, you can place larger bets than you would on slots with high volatility. Moreover, a bigger bet improves your odds of hitting one of the three progressive jackpots.

4. Take Advantage of Bonuses

One of the many perks of slots online is access to casino bonuses. Land-based casinos don’t normally give you free money as soon as you walk through the door. However, the best online casinos have welcome bonuses, reload bonuses, loyalty rewards, and other deals that can you benefit from.

5. Try Out the Gamble Game

Having an even odds gambling game can represent another advantage when playing slots. That’s because the payouts from the spins vary quite a bit. So, when you do land a large win in Star Gems, gamble it once for the chance to instantly double the prize. The 50% chance is much better than the odds you have of hitting the win again.

Play Free Space Gems Slot Online

The free Star Gems slot is perfect for a fun session and for trying out the game. It has all of the same features, except for the progressive jackpots. You can try out different betting levels with a starting bankroll of $5,000 in demo credits. We also like that you can access the gamble game as well to see how it fits your playstyle.

The practice balance allows you to keep track of the results. Once you feel confident that this is the best game for you, you can switch from the free version to the real money one.

For even more free slots, we recommend checking out MyB Casino. The site presents a wide range of slot games and you can try them out in practice mode right away. You don’t even need to create an account. Simply click on the game you want to play and it will start up in demo mode.

Play Space Gems Slot on Mobile

Star Gems is available on mobile and loads quickly from the browser. It works best on Chrome and Safari, so it has great compatibility with Android and iPhone devices. The game keeps the same theme and features, including the Fazi progressive jackpots.

There are some shortcomings when it comes to the Star Gems mobile app. First of all, you can only play in landscape view as portrait mode is not supported at this time. Furthermore, the controls aren’t perfect and the spin button covers the fifth reel a bit. While it isn’t the best mobile-optimized slot, it gets the job done and is worth checking out.
