Reef Raider Slot RTP, Details & Wager Limits

Bet levels range from 20p to £100 per spin. Click on the coins icon then choose from the various bet levels shown. For the paytable, click on the i icon. Payout amounts are shown in cash and are relative to the current stake level.

The Reef Raider RTP is 96.02% which is pretty standard. The volatility is in the middle (medium) which balanced payouts throughout the base game and various bonus features. The game has a potential maximum win of 8,500 x your total stake.

Theme – Audio & Design Features – join the coolest crab this side of Tortuga


With a pirate theme, there’s a simple, cartoon style to the visuals in the Reef Raider slot. With aquatic plant life fluttering in the background, the imagery here is colourful and clear which is all you really need.

This tongue-in-cheek offering is bas­ed on a crab who roams the ocean floor. The rather jolly soundtrack bounces along nicely too without being overly intrusive. It reminds me a little of SpongeBob Squarepants.

The reels are made up of 4 lower value shell symbols and 4 more rewarding gems. The top standard symbol is the red jewel which pays 150 x your total stake if you land a cluster of 25 or more matching symbols.

Reef Raider comes with 2 different wild symbols: clam wild and coin wild. Land a winning cluster that contains 3 or symbols and a Clam Wild is added to one of the vacated positions before the next avalanche takes place. The Coin Wild can land in the base game and free spins when the Random Wilds or Cannon Blast modifiers are activated (more details below).

Using HTML5 technology, developer NetEnt has created fully optimised versions of Reef Raider which are available to play on desktop, tablet and mobile.

Reef Raider Bonus Features

This underwater adventure bubbles along nicely thanks to the wide variety of extras it offers. Reef Raider offers a total of 7 bonus features. They include 4 different modifiers, 2 different wilds and a free spin bonus, complete with mystery symbols.

Avalanche feature

When a winning cluster is created, the Avalanche feature is triggered and an avalanche follows. The successful symbols are blasted off the reels and new ones drop in and replace them. If a new winning cluster is formed, the process is repeated. Each successive avalanche also charges a Treasure Trail meter which can bring features into play. These are described in more detail below.

Multiplier feature


Land a multiplier symbol adjacent to a winning cluster either horizontally or vertically and the Multiplier feature is activated. The payout is boosted by the amount shown. These multipliers can be worth 2x, 3x, 5x or 50x.

Treasure Trail features


Land a succession of avalanche wins and you’ll charge the Treasure Trail meter which is made up of 15 stages. You need to land 3 or more wins in a row to trigger a bonus feature.

  • 3 Avalanche Wins = Anchor Drop feature: 1, 2 or 3 lower value symbols are picked at random and removed from the game grid. A new avalanche then follows.
  • 6 Avalanche Wins = Random Wilds feature: between 4 and 8 Coin Wilds are added to the grid. These substitute for everything apart from the multiplier symbol.
  • 9 Avalanche Wins = Mystery Chest feature: Mystery Symbols replace between 2 and 16 low and medium value symbols. These all transform into the same symbol and a new payout consideration is made.
  • 12 Avalanche Wins = Cannon Blast feature: 1 symbol is removed from play. All the low and medium value symbol on that row and column are also removed and a new avalanche follows.

Free Spins feature


To trigger the Free Spins feature, you need to charge all 15 positions on the Treasure Trail Meter. You’ll then go on to play a minimum of 9 free spins. A further 2 free spins are awarded for every 3 charged bars on the Treasure Trail on the triggering spin.

During the free spins, the Mystery Overlay is active. 1 mystery symbol is placed in the central position on the grid with 4 more added vertically and/or horizontally. Mystery symbols will transform into the same matching symbol on each free spin. You can add even more Mystery Symbols to this cluster throughout the feature. These too lock in position and remain active for any free spins you have left.

The Treasure Trail Meter is active during the free spins too. You can land the 4 Treasure Trail features and also add more free spins to your total. Fill all 15 bars to add 1 more free spin to your tally.

Reef Raider Review Summary – take and plunge and raid rockpool riches

There’s a lot more to the Reef Raider slot than what you might expect from first view. With its madcap theme and colourful visuals, the king of the rockpool can reward you nicely.

The key to success is getting on a run of successful avalanches which can bring the a variety of features into play. This can lead to the Free Spins feature where these modifiers apply as well as mystery transforming symbols.

However, the biggest wins will come from the Multiplier feature with the 50x multiplier symbol the one you want to land next to a big winning cluster. Ideally you want to combine to multiplier symbol with a large number of mystery symbols in the free spins.

The good thing is that you can win the max 8,500 x stake payout on a base game spin as well as in the free spins. Design wise, it’s typical NetEnt and does the job nicely. Combine that with the varied gameplay and Reef Raider has plenty to offer.

If you want more pirate plunder, Push Gaming’s Booty Bay slot also uses a Cluster Pays engine. There are plenty of bonus features with bigger max win potential up to 20,000 x stake per spin. Another good option is Rage of the Seas by NetEnt. With up to 5,488 ways to win, it has choppier waters but with 27,440 x stake max wins.
