Rainbow Ray Slot

Rainbow Ray πŸŒˆ is a slot game launched by Endorphina in March 2024. From one of the leading iGaming providers, we've come to expect nothing but creative games with well-designed graphics and a range of extra features that promise great prizes. And Endorphina will not disappoint its players this time either.

Rainbow Ray is built around the familiar themes of four-leaf clovers, leprechauns, rainbows and treasure at the end of the rainbow. Can anything new come out of all this? We will see.

But if you'd like to see for yourself if it's worth spending real money on, try the demo version of Rainbow Ray first. You will usually find it on the website of any online casino where Endorphina is listed as one of the game providers. But I've brought you some online casinos where you are more than likely to find it:

  • PowBet
  • Cadoola
  • Novajackpot
  • Verde Casino
  • Weiss Casino

If you want to learn more about these casino sites, you can find thorough reviews on our website.

Rainbow Ray – Characteristics

Game provider Endorphina loves working with familiar themes and symbols. In the case of Rainbow Ray, we are dealing with a classic slot game. Unlike the vast majority of Endorphina slots, we are dealing with a bit more reels, as this slot has 6x5 reels.

Your minimum bet can be β‚¬0.20 and your maximum bet can be β‚¬100. Your maximum win can be up to 6000x your bet πŸ’°, which doesn't sound bad at all. In terms of volatility, we can't be completely sure, but if you ask me, from what I've seen so far, Rainbow Ray is a medium volatility slot game.


Rainbow Ray has an average RTP of 96.12%. Not a bad rate, but you should know that it can vary. Before you start playing, check the exact RTP of the game at the casino you are playing at. That way you can be sure not to get any unpleasant surprises.

Rainbow Ray – Functions

If you think the game is slow, you can easily set a faster speed by clicking on the turbo button. Basic features also include the ability to set automatic spins. You can also check out the rules of the game, as everything is very clearly and precisely described.

There are a total of 30 different symbols (four-leaf clover, heart, harp, leprechaun, horseshoe, mushroom πŸ„ etc.) and to win a prize, you need at least 8 of the same symbol to appear on the reels at the same time. With 12 or more matching symbols, you can win up to 50x your bet.

All symbols are scatter symbols and no matter how they are positioned, the key is to get as many of the same symbol as possible. If there are enough matching symbols on the reels, you have a winning combination. If there are several of them on the reels at the same time, then only the longest combination is the winning combination.


One of the interesting features of the game is the rainbow symbol, which adds an extra charm to the whole game. These magical symbols increase your chances of getting bigger prizes.

During free games, 2x and 100x Multiplier symbols appear on the reels but remain inactive until the end of the winning combination. They then add up and are added to the win.

Another Endorpina feature is that you can win up to 10x your bet if you're feeling brave enough during the Classic Risk Game. Plus, there's Bonus Pop!

Free Spins

If the Leprechaun symbol appears 4x or more, you can win 10 free spins and 100x your bet. To trigger this feature, you need at least 3 Leprechaun symbols.

Rainbow Ray – Theme and design

It seems that there's more to show about the cheeky leprechauns, rainbows and the treasure at the end of the rainbow. The design of the game really brings a world of legends to life. The background is a beautiful clearing surrounded by trees. Just the kind of place where leprechauns would live πŸ€. If you're wondering what treasures this magical place has in store for you, you're just a few clicks away.

You can also see the rainbow in the background of Rainbow Ray, and the leprechaun will guide you through the game. With each winning combination you get closer to the secret treasure lurking at the bottom of the rainbow. Make the most of the guaranteed prizes with the game's varied symbols and hit the maximum win!
