About Reef Raider

Reef Raider by NetEnt is a happy, silly slot with a cute, colourful theme. It has 7 reels and 7 rows; 49 symbols drop on your screen when you hit the spin button.

They are of 8 types – four gem symbols that bring medium wins and four shell symbols that bring low wins. 5 or more of the same symbols in a cluster award a win.

The stake levels range from €0.2 to €100 per spin. Reef Raider slot resembles NetEnt’s Finn and the Swirly Spins and bears a similar setup, only under the sea.

It exudes a pretty laid-back feeling enunciated by the reggae music track that runs in the background. Packed with multiple free spins and bonuses, this is a kind of slot game you want to play when you are feeling leisurely.

Volatility, RTP and Other Details

Reef Raider is a high volatility slot. Therefore, wins throughout the base game and bonuses would not be a lot to show for it.

However, with some luck, everything should line up just right, leading you to some big wins for sure. The biggest win is 8500x your total stake.

The RTP of the slot is 96.1%, which is decent. For every 100 you bet, you should theoretically get back 96.1. In this slot, 5 symbols in a cluster register a win, which then triggers the Avalanche feature.

Once it starts, symbols in winning combinations explode to make room for yet another Avalanche. It continues until there are no more wins.

Central to the gameplay is the Treasure Trail meter, which comprises 15 meter bars running around the grid. One bar is charged every time a Clam Wild (discussed later in the review) is removed due to a cluster win.

Once all the 15 bars are charged, free spins are triggered. A lobster pirate moves along the charged bars, activating features at four points on the Treasure Trail.

Reef Raider Features


Reef Raider slot features two types of Wilds: Clam and Coin. A Claim Wild appears after 3 or more symbols form a cluster win. Coin Wilds appear on the reels in the base game, during free spins and when the Random Wilds and Cannon Blast are activated.


Multiplier symbols can land either vertically or horizontally next to a winning cluster to multiply wins by 2x,3x, 5x or 50x.

Treasure Trail Features

  • Anchor Drop

It is triggered when 3 Treasure Trail meter bars are charged. Upon its activation, 1 to 3 low win symbols are randomly chosen and the matching symbols removed.

  • Random Wilds

It is triggered when 6 Treasure Trail meter bars are charged. Upon its activation, 4 to 8 Wild Coin symbols randomly appear on the reels.

  • Mystery Chest Feature

It is triggered when 9 Treasure Trail meter bars are charged. Upon its activation, 2 to 16 medium and low win symbols on the reels are replaced with Mystery symbols, which might hold potential cluster wins.

  • Cannon Blast

It is triggered when 12 Treasure Trail meter bars are charged. Its activation removes a random symbol along with all the medium and low win symbols that are there on the same row and column. Please note that this feature does not remove Clam Wilds, Coin Wilds and Multipliers.

  • Mystery Overlay and Free Spins

When all the 15 bars are charged, it triggers free spins. Thereon, 1 or more free spins are triggered for every 3 extra charged bars.

Once you enter free spins, the Mystery Overlay feature is activated, letting 5 Mystery symbols appear on the reels. One symbol falls on the play area while the rest are placed horizontally and vertically next to it. Mystery symbols hold potential cluster wins.


NetEnt’s Reef Raider is a quirky, colourful, pirate-themed slot with plenty of fun features. Design is neat and the gameplay simple.

Triggering a series of Avalanches is the key here. Of course, getting to the Free Spins can be difficult. However, combined with the Multipliers and Treasure Trail Features, this slot is more than meets the eye.

Join a kooky, rum-coloured lobster pirate in a rock pool in this enthralling underwater adventure. Dive in and give Reef Raider a spin today. Good vibes incoming!
