How to play

The playing field with 6 reels in 8 rows set against the background of the starry sky. Winning combinations are not made on paylines, but in accordance with the Cluster Pays mechanic, which offers you to collect 5-15 + copies of 1 symbol in a cluster to get a payout. All icons participating in the winning cluster are removed from the playing field using the Avalanche feature, and this is how the Gravity mechanic comes into play! Then new and/or existing icons fall into empty spaces, and this can lead to the new victorious clusters! This funny process repeats as long as you keep winning.

To start this amazing adventure right now, you need:

  • Open the slot here for demo or in casino to play for real
  • Check out the paytable and rules
  • Choose the stake size: from €0.20 to €100
  • Spin the reels!

Stars of Orion RTP and Volatility


High risk comes with a 95% return.

Well, you have to work hard to get the cluster pays mechanism to work to your advantage, as the slot comes with high volatility. This means that here you will receive a lot of dead spins, but on the other hand, each cluster will bring a big prize, especially during bonus features! An RTP of 95%, which is below the market average, makes the mathematical model even more unfriendly.



Stars of Orion

Have you ever heard of Orion? Strange if not, because this is one of the most famous constellations in the region of the celestial equator. Named after the hunter Orion, this hunter constellation can be seen from anywhere on Earth! It is so remarkable that people looked at it while sitting by fires in the Stone Age. Now we have seen the galactic hunter again, this time in the Stars of Orion slot!

Orion illuminates the sky in the background and stone monoliths similar to Stonehenge stand on the ground. Balls appear on the large playing field. The low-paying balls are multicolored, and the premium ones are golden with the image of wild animals and Lucky 7. They are bright and stand out well against the general dark background.

About ELK Studios

It's time to talk about ELK Studios! This new star in the gambling sky is a young provider from Sweden that specializes in top-notch slots for mobile devices. These guys prioritize quality over quantity, so you won't find many games in their portfolio. However, every release from ELK is capable of surprising even the most sophisticated gambler. The excellent interaction of the development team and creative directors has helped them create some of the most beautiful-looking and well-performing games on the market. In addition to top-notch graphics and well-balanced mathematical models, their products support 20 different languages as well as many currencies.

Bonus Rounds & Free Spins



Be prepared for any regular symbol to land as a super symbol! After that, you will notice a blue glowing frame around the symbol. When a super symbol hits a prize cluster and simultaneously connects to another winning cluster, all of the winning symbols are converted to the high-paid symbol type, which is part of what happens.

All winning symbols are collected in a special counter, which is located to the right of the playing field, and this counter awards the multipliers gradually. Possible multipliers: 2x-4x, 8x, 16x, 32x, 64x.


There are also gems in between the multiplier sizes that activate cool modifiers. By filling the counter 2 times for 1 Avalanche sequence, you will receive a multiplier and a feature. Modifiers work as follows:

  • Symbol Swap: symbols are swapped to create at least 1 win
  • Orion's Belt: Lands 3 Wilds on the playing field in the corresponding shape
  • Orion's Club: Lands 6 Wilds in the corresponding shape
  • Orion's Shield: Lands 8 Wilds in the corresponding shape
  • Orion: Lands as many as 13 Wilds in the shape of the Orion constellation

Bonus Round

When 3 Scatters land on the playing field (anywhere), it gives 10 free spins. The Magic Meter does not reset between them, and special Super Bonus symbols can trigger the Super Free Spins version if all 3 trigger symbols receive a red frame. In Super Free Spins, Super symbols land more often. You can also take advantage of the X-iter Buy Feature which offers 5 different options: Guaranteed Win, Super Symbols, Symbol Swap, Free Spins, and Super Free Spins.

Overall Rating

To be honest, we are unhappy to see RTP falling steadily since the release of the first ELK’s game with gravity mechanics. The RTP of 95% which is below the market average is really sad, as otherwise, Stars of Orion is the best game in the series. We love the mysterious space atmosphere that hovers over this release, as well as the tons of multipliers, modifiers, super symbols, and free spins. The gameplay becomes quite fun and profitable when you get caught in a long chain reaction and a solid 10,000x potential is double what was suggested in previous releases!

Orion’s Modifiers
