Great Reef RTP and Volatility


Great Reef is a low volatility slot with an RTP rate of 96.64%.

This game has a low variance rate which will be good news for players who prefer lots of small wins and don’t like to take many risks. The RTP of 96.64% slightly above the industry’s average of 96%, and it basically indicates that the game will return €96.65 to the player in payouts for each €100 wagered in the long run.


Great Reef

This game will take us deep below the surface of the ocean, where the reels are set against a royal blue background. Streams of bubbles come up to the surface and pink and purple corals sway gently in the current. The underwater sounds add to the overall experience and make you feel like you’re scuba diving.

The list of symbols of the Great Reef is quite short, and you’ll see card royals (paying from 0.2x to 4z), starfish, a seahorse, and tropical fish on the reels, followed by the higher-paying turtle (0.6x-10x) and shark (0.2 to 20) symbols. Like all the other symbols, they have a cartoonish look that makes them seem quite friendly. The special symbols are represented by a pirate Wild that substitutes for all the regular symbols, and a Scatter which is depicted as an oyster. The combo of 3 or more Scatter will award you with up to 33 free spins with a 6x multiplier.

Max Win


The top win is 3,000x your bet.

This low-volatility slot machine has a rather good winning potential with the biggest possible prize worth 3,000x bet. To win such a prize you’ll need to fill the reels with the highest-paying shark symbol coupled with a 6x multiplier during the Free Spins round. So, if you want to win bigger prizes, look out for Scatters to trigger the Free Spins bonus.

Overall Rating


Deep Reef is a straightforward classic slot game, but this does not necessarily mean that you’d get bored while playing it. However, the short list of symbols and very basic bonus are anything but original. If you are a fan of underwater worlds in slot games, then Great Reef will be a nice choice for you. Beginner players can also like this title and get an easy start in slot gaming.
