Reef Raider Online Slot Review

NetEnt has created many Cluster Pays titles so far, but the latest one is such an exciting one that really deserves your attention. Designed on a 7x7 grid, the slot offers an underwater theme, where you’ll be surrounded by sea creatures, Reef Raider is presented with cartoony graphics, with bright colours and a happy vibe.

You’ll benefit from the many features involved, not only the Cluster Pays mechanics, though. The slot comes packed with Wilds, Multipliers, the Avalanche feature and the Treasure Trail, packed with modifiers. Plus, you’ll get access to Free Spins, and the Mystery Overlay feature. If all of this sounds exciting, stay with us to find out how to trigger all of these features and modifiers.

How to Play Reef Raider Slot

Like all slot games from the leading development studio, naturally, Reef Raider is playable across both desktop and mobile devices. All you need to do is load the game on any device you have, and it will play smoothly. The grid is at the centre of the screen, and below it, the control buttons.

You will first see the three-bar button where the game's rules are. The "i" button is next, where you'll find all the symbols, as it takes you to the paytable. The low-paying are the colourful sea shells, the mid-paying are the different coloured gems, offering up to 150x the stake for the best clusters, but you'll also see the Wild and the special Multiplier icon, with values of up to 50x. Next, you'll see the bet configuration field, where you could place bets from 0.20 to 100 credits per spin, followed by the Play and Autoplay buttons. The Win display will be followed by the last display, the Balance display.

Reef Raider Features and Free Spins

The Wilds in Reef Raider slot play their usual role of substitutes. They will help you form winning clusters whenever you’re lacking a symbol. Winning clusters will be removed from the grid, and with the avalanche feature, new symbols will fall into their place, taking you to consecutive wins. When this happens, though, the Wilds will remain, doubling your chances for great prizes.

As mentioned earlier, there will be a Treasure Trail, tracking your progress throughout the game. When you hit 3 meter charges, one of the four modifiers will trigger. You could get the Cannon Blast which chooses one symbol at random and removes all symbols from the same column and row. Mystery Chest is another modifier you could get, replacing 2 to 16 mid-paying symbols with Mystery Symbols, which eventually transform into the same matching symbol. You could also get the Random Wilds feature, where at random, 4 to 8 Wilds will appear on the grid. And lastly, you could trigger the Anchor Drop, removing 1 to 3 low-paying symbols from the grid, at random.

You trigger 9 Free Spins with 15 meter charges. Charge the bar 3 more times and you’ll get 2 extra Free Spins. During the Reef Raider bonus game, should you charge 15 bars again, you’ll get 1 extra Free Spin, plus 1 for each time you charge 3 bars. But, here, the Mystery Overlay feature gets active as well. On the pattern beneath the central symbols on the grid, Mystery Chest symbols may appear. They will reveal a winning cluster, plus there’s a chance for new random Mystery symbols to appear and join the cluster.
