Reef Raider review

Dive beneath the ocean to discover the pirate crab known as the Reef Raider. Reef Raider is a 7×7 grid-shaped slot that features the avalanche mechanic. It comes with several bonus features that players will enjoy.

In this Reef Raider Review, we’ll go into a bit more detail to evaluate whether the slot is worth your stakes!

How I tested Reef Raider

When testing the Reef Raider slot, there are some factors that I considered. I’ve liste these below.

  • Layout and Design: The layout and design of the slot to ensure it’s easy to navigate. If a game’s functionality is not top-notch, players might find it challenging to play the game. 
  • RTP and Volatility: The slot RTP percentage is above average, which is good for casino players. Additionally, it has a high variance, meaning that the payout can be huge. 
  • Bonus Features: When testing this slot, I discovered that players would enjoy several bonus features to increase their chances of winning. These bonus features include multipliers, free spins, Random Wild, Mystery Chest, Mystery Overlay feature and many more.

Enjoy the Reef Raider with the best casino bonus

Bonuses are one of the ways to increase your winning chances when playing casino slot games. It gives you more chances to extend your gameplay. To enjoy the slot, we recommend you play at the best online casinos. Ensure the casino is reliable and trustworthy.

Reef Raider Slot Symbols & Payouts

The Reef Raider slot features carefully designed symbols that can offer good payouts once you land clusters of 5 or more.

The Symbols

The symbols include both low and high-paying symbols. The low-paying symbols in the game include shells that come in various colours: purple, blue, green and yellow.

Additionally, the high-value symbols are the gemstones, which also come in different colours. You can land red, purple, orange and green gemstones on the reels. 

In the Reef Raider slot, the treasure chest is the mystery symbol and two different wild symbols.


The game pays out for every cluster of 5 or more like symbols. The highest paying symbol is the red gem stone, which pays out 150x the stake if you get a cluster of between 25 and 49 symbols. This is followed by the pink gem, the orange and the green.

Reef Raider minimum & maximum bets, autoplay option?

Before you start to spin the reels, you need to set your bet limit. The bet limit starts from a minimum of £0.20 to a maximum of £100.

Additionally, there is an autoplay option that you can use to set several spins at a time. The autoplay function settings can be between 10 and 1,000.


One of the things I liked about the slot is its very decent RTP of 96.02%. A slot’s RTP is the average amount that a specific game will give back to the player out of all the wagered money in the long run. The Reef Raider RTP value means that for every £100 wagered, it’s likely that you get back £96.02 in the long run. 


The volatility of a slot is the amount of risk associated with a particular slot. The Reef Raider is a medium volatility slot. So the payout is balanced throughout the game and the various bonus features. 

Hit frequency

During the Reef Raider review of the slot, we discovered that the hit frequency is around 32.43%. So you should expect to win pretty often, but consecutive wins are harder to achieve.

Jackpot and/or maximum win

Though the Reef Raider is not a progressive jackpot slot, players will still enjoy massive wins. The slot can give you up to a max win of 8,500x your bet

Reef Raider has a good RTP, but bonus hit frequency is low!

The Reef Raider slot features a flexible bet limit that makes it playable for low-risk players. However, we noticed that it takes a good number of spins to get 3 or more consecutive wins and unlock the features.

Game Features

Reef Raider slot comes with a nice blend of features both during the base game and bonus round. We’ve summarized how these work for you below:


You’ll come across two wild symbols in this slot – clam wild symbols and wild coin symbols. The wild symbols can substitute every other symbol on the reels to create a winning combination. Additionally, the wild has the biggest winning combinations possible.


Another highlight in the game is the multiplier. When a multiplier lands (vertically or horizontally) adjacent to any winning cluster, it multiplies that wins by its value of: x2, x3, x5, or x50. 

Treasure Trail Feature

As soon as you start landing wins, you will activate the treasure Trail Feature, whereby the box around the reels will start to charge. If you manage to land 3 or more consecutive wins, you’ll then unlock the following bonus features:

Anchor Drop 

When you land three Avalanche wins, you trigger the Anchor Drop Feature, and when this happens, one to three low winning symbols will be chosen randomly, and they’ll disappear from the reels. 

Random Wild 

The Random Wild Feature triggers when you get six consecutive Avalanche wins. It will randomly place four to eight Wild Coins on the slot reels. 

Mystery Chest 

Landing nine charged bars triggers the Mystery Chest Bonus Feature. Here, two to 16 low and medium win symbols on the slot reels are substituted with Mystery symbols. 

Cannon Blast 

The Cannon Blast Feature triggers when you land 12 Avalanche wins. A random symbol alongside all low and medium win symbols is eliminated from the slot reels when this feature activates. 

Reef Raider Free Spins

Landing 15 or more Treasure Trail meter bars in the main game will give you free spins. When you land an extra three charged bars, you get another two free spins.

During the free spins round, 15 charged bars reward you with one free spin, and three extra charged bars award an additional free spin. 

What’s more, the Mystery Overlay feature is active during the free spins round. This involves a Mystery symbol that you’ll see in a central position on the reel set, which will transform into the same symbol after each free spin.

Great mix of feaures, but incredibly difficult to trigger the free spins!

While we loved the multiplier feature and the win potential, we must say that we found it incredibly hard to fully charge the meter and unlock those free spins. Maybe it was just our luck, seeing the meter reset to zero with each non-winning spin did drain some of the excitement.

Reef Raider Graphics & Sound  

Reef Raider comes with incredible graphics that players will find appealing. The symbols are carefully designed, making the game more interesting. The slot engages you with an excellent sound when you spin the reels as the symbols fall in. The rather jolly soundtrack bounces along nicely too without being overly intrusive. It reminds us a little of SpongeBob Squarepants.

Additionally, the game interface is user-friendly, so players will find it easy to navigate the game.

Reef Raider offers a fantastic user experience

With the top-notch graphical interface, we are sure that players will have a wonderful experience while playing the game. The game background is simple yet beautiful. It’s highly responsive across all mobile devices.

Solutions if you have some issues with a game  

While the game normally runs smoothly, you’ll run into some issues. Here are the solutions to some of these issues. 

  • If the replay functionality is not working perfectly, you can reach out to the casino support team.
  • If the game hands at some point, close the game and restart it. 


The Reef Raider is an incredible and fun game to play. It comes with several bonus features that you’ll enjoy, but some of them are very hard to trigger.

With medium variance and decent payouts, we’re sure players will enjoy playing the game. Overall, we gave the video slot a 4.0 rating.
