Who doesn’t love a good underwater slot adventure? Reef Raider by NetEnt is a fantastic adventure under the sea next to an amazing coral reef starring a funny crab pirate captain in the lead role. A colorful slot with fun gameplay – don’t mistake it with Reef Raider for a low-paying slot machine. It uses the Cluster Pays engine to blow up clusters of colorful symbols, giving you a chance to win rewards up to 8,500x your stake.

Reef Raider is a medium-volatility slot game with an RTP of 96.1%. Blowing up clusters of symbols in it can lead to big wins. Like all NetEnt titles, it’s a slot that tries and succeeds in doing things differently.

Those who love underwater slot adventures will surely like what Reef Raider has to offer. Take a deep dive into the coral-rich sea and enjoy the slot for free or real money in the top NetEnt online casinos.

As a Cluster Pays online slot, Reef Raider has a 7x7 grid. On the grid, you’ll find various water symbols, including colorful shells and gems. You’ll also see a special symbol in each corner of the grid, which indicates one of its special features.

There are two Wilds in this slot – the Clam Wild and regular Wild Coin. The first one appears when a winning cluster of 3 or more low or medium-win symbols is removed from the grid. Instead of spinning, the slot uses the avalanche feature, which is common for Megaways and Cluster Pays titles.

Like all NetEnt slots, Reef Raider looks pretty great. It’s a pretty colorful and lighthearted slot game that will surely appeal to new and seasoned spinners.

The slot was developed on HTML5 technology, so it’s ready to be played on Android and iOS devices. You don’t need to download it – just head to your favorite NetEnt casino from your phone and play it from your browser.

To start playing, you will need to place a bet between $0.20 and $100 per spin. Hit the Spin button when you’re ready to play or use the Autoplay feature if you don’t want to click on your mouse all the time.

The main feature in the Reef Raider slot is avalanche wins. Whenever a cluster pops up on the grid, new symbols will appear on the empty spaces. The avalanches will continue as long as there are winning symbols on the screen.

Land successive wins to fill the Charge Metre that frames the grid. It has 15 levels in total and gives you access to one of the special features whose symbols can be seen in the corners.

• 3 successive wins: Anchor Drop – removes 1, 2, or 3 low-win symbols from the grid with an avalanche to follow.

• 6 successive wins: Random Wilds – adds 4-8 coin Wilds to the grid.

• 9 successive wins: Mystery Chest – 2-16 low- and medium-value symbols are replaced by mystery symbols. They are then transformed into the same symbol and deliver a new payout.

• 12 successive wins: Cannon Blast – removes one random symbol from the grid, followed by all low- and medium-win symbols before a new avalanche.

That’s the first feature worthy of a mention. You can also land multiplier symbols adjacent to winning clusters to trigger the Multiplier feature. The multipliers can be as low as x2 and as high as x50.

Charge all 15 levels on the Treasure Trail, and you’ll trigger the Free Spins Round. You get a minimum of 5 free games plus 2 extra free spins for every 3 bars charged. The Mystery Overlay is active in the Bonus Round, putting one mystery symbol in the center and 4 more horizontally and vertically on the grid.

With a bit of luck, you can land more mystery symbols that transform into matching ones. The Treasure Trail feature is still active in the Bonus Round. You can trigger the 4 special features and land more free spins by filling the Treasure Trail bars.

The RTP of the Reef Raider slot has been set to 96.1%. That’s pretty common for a Cluster Pays highly volatile slot that can deliver wins up to 8,500x your stake.
