Reef Raider Slot Review

Last updated: September 21, 2021

Netent's Reef Raider Slot takes you on an aquatic journey to the illustrious corals deep below, where you'll encounter a rum-coloured crustacean chappie known as the Reef Raider. He’s a crab pirate! 'Oooer! The idea of this slot is that he's going to help you raid and loot gold coins and hidden treasures from the depths beneath to assist you in bringing up to x8,500 your stake home! This Reef Raider Slot review will cover everything you need to know about this game before you play it as well as which trusted casinos we'd recommend playing it at as well.

Reef Raider Slot Introduction

Released in July 2021, Reef Raider is a tongue in cheek online slot game from Netent. Designed with a whimsical underwater cartoon theme and a jolly soundtrack, this could be one of Netent's most 'cute' slots yet. Reef Raider slot is played out on a 7×7 game grid and has a 'Cluster Pays' mechanic combined with NetEnt's famous Avalanche feature. The grid is adorned by seashells, Maps and Jewels, with the background depicting the sea bed with light beaming on it. Honestly, it looks so inviting and it's just a cartoon! Kudos to the design department, they've made this game very easy on the eye. Anyway, that's enough daydreaming of a Caribbean holiday for us, lets get back to the matter at hand: this Reef Raider slot review! 

How To Play Reef Raider Slot

To play Reef Raider Slot, head to your desired casino that offers Netent games. If you're looking for a brand new casino and welcome bonus, we recommend our handpicked online casinos below that offer Reef Raider slot and many other popular UK slots. The bet levels for this game range from 20p to £100 per spin. To set your preferred bet amount per spin, click on the coin icon to set the coin and betting level. You can view the game paytable and rules by clicking on the "i" icon, where the payout amounts are displayed in cash and are relevant to the current stake level. Once you're all set - it's time to spin the reels which, as we mentioned don't actually spin in the traditional sense in this game, they will 'fall' due to Netent's popular Avalanche feature.

Reef Raider Slot Features

Winning combinations in the Reef Raider slot are created by landing clusters of 5 or more matching symbols or Wilds. The bigger the cluster, the larger the win will be. However, Reef Raider is packed to the brim with in-game features designed to engage and entertain you:


A standard icon and feature in most online slots, the Wild icon in Reef Raider substitute for all paying symbols, though in this game there's a twist to the norm. The Wilds in this game come in two different forms: a Clam Wild and a Wild Coin. You’ll notice the Clam Wild symbol appear in place of one of the eliminated win symbols during a cluster win. The Wild Coin symbol is directly linked to the Treasure Trail meter (see below) and appears in the main game and also the free spins feature.

Avalanche Feature

When a winning cluster is formed, you'll activate the Avalanche feature. You can see this familiar feature in a few other popular Netent slots, including Gonzo's Quest and Pyramid: Quest For Immortality. Avalanche reels are where participating symbols explode and vanish from the grid, with new ones descending into place to substitute them. This process will repeat itself if you form another winning cluster. Each consecutive avalanche feature will also charge a meter which can trigger the Treasure Trail feature (below).

Treasure Trail Feature

This brings us on nicely to the fun Treasure Trail feature. The Treasure Trail meter, which can be seen framing the game’s grid, is active all the time. As mentioned above, you will charge the meter when you get 3, 6, 9, and 12 consecutive wins. When you achieve those, you will unlock certain special bonus features positioned around the grid. They are as follows:

  • 3 Avalanche Wins will trigger the Anchor Drop feature. 1, 2 or 3 lower value symbols are picked randomly and dismissed from the game grid. A new avalanche will then follow.
  • 6 Avalanche Wins will trigger the Random Wilds feature. Between 4 and 8 Coin Wilds will be added to the grid. These substitute everything aside from the multiplier symbol.
  • 9 Avalanche Wins will trigger the Mystery Chest feature. Mystery Symbols will replace between 2 and 16 low and also medium value symbols on the grid. These will all then transform into the same symbol and a new payout will be formed.
  • 12 Avalanche Wins will trigger the cool Cannon Blast feature. 1 symbol is removed from play at this stage. All of the low and medium value symbols on that row and column will also be removed and a new avalanche will then follow.

Reef Raider Free Spins Feature

To activate the free spins feature in this game, you need to charge the meter with 15 or more symbols. You then get 9 free spins for the first 15 collected symbols and then a further 2 free spins will be awarded for every 3 charged bars on the Treasure Trail thereafter. Further to the free spins being granted, during this feature, the Mystery Overlay feature is activated too, which is a pattern beneath the symbols in the centre of the grid. 1 mystery symbol is placed in the centre position on the grid with four more added vertically or horizontally. Mystery symbols will then transform into the same matching symbol on each free spin. You can also add even more Mystery Symbols to this cluster throughout the feature; they will lock into position and remain active for the free spins that you have left.


If you didn't think the features above were enough, then there's one more: everybody's favourite: Multipliers! If you land a multiplier symbol next to a winning cluster either horizontally or vertically, the Multiplier feature is initiated. Multipliers can be worth 2x, 3x, 5x or 50x. The payout is increased by the amount shown onscreen. 

RTP % & Volatility

Reef Raider slot has an RTP of 96.02% which is pretty standard for online slot games in today's casino world. With regards to how the game plays, according to Netent, the game's developer, Reef Raider is a medium volatility slot game. This means the game offers balanced payouts throughout the base game and nothing too swingy - perfect for all types of players!

Maximum Win Potential & Jackpot

There isn't a jackpot available in this game; we're guessing the game was a bit too jam-packed already to make room for a huge jackpot feature, but that's not to say you can't win anything decent. The Reef Raider max win potential is a whopping 8,500x your bet. To win this amount, you'll need to charge up the Treasure Trail meter and land free spins with mystery overlay symbols in a winning combination cluster.

Reef Raider Mobile Slot

Using HTML5 technology, NetEnt has produced fully optimised versions of the Reef Raider slot which are available across all devices. You can play Reef Raider slot on desktop, tablet and mobile; it's entirely up to you when you play, how you play and where you play. If you do opt to play Reef Raider mobile slot, you won't be missing out on anything from the desktop version as nothing is compromised. The game works perfectly on mobiles and easily on a smaller screen. Some people claim that Netent slots are better on mobile, but the fact remains you will still have an HD game experience if you choose to play this game on a mobile device.

Reef Raider Slot Review Verdict

Reef Raider bears all of the hallmarks of a prime Netent slot. It's an incredibly fun slot to play (and not only because it offers a happy theme with a cheeky rockpool dwelling crustacean - though, that helps) But on a serious note, there are a ton of amusing in-game features to keep everyone enthralled. They of course each pave a way to help you win up to 8,500x your bet. This mammoth win can be achieved both in the base game and in the free spins feature accordingly. 

The game is mostly powered by successive avalanches, which will trigger numerous features, including the free spins rounds and the Treasure Trail feature. We have been impressed by this slot on all fronts. Players of all budgets will find this game friendly and accessible. In addition, since this is a medium volatility slot, it also doesn't make the game very risky, therefore, this game is a fun all-rounder suitable for all types of players.

If you've decided Reef Raider is a slot for you and you want to give it a shot, you can do so at most online casinos that have implemented Netent Games. With Netent being one of the leading and most respected casino game providers, it's not hard to find an online casino site with Netent slots.
