Reef Raider Bonus Features

Reef Rider is jam-packed with bonus features. Central to the game is the Treasure Trail, consisting of 15 charge bars and 4 special bonus rounds. Charging the bars and moving along the trail is what makes this game exciting. Another thrilling part here is the Avalanche feature. Landing 5 or more adjacent symbols forms a winning cluster and causes a tumbling action, during which all winning symbols are replaced with new ones for the possibility of multiple wins on any single spin. Even more so, unlike many other avalanche games, you’ll have a wild added to the grid if a winning cluster contains at least 3 medium or low win symbols. Let’s inspect all slot features more closely.


Wilds in Reef Raider substitute for all paying symbols and come in two different forms – Clam Wild and a Wild Coin. You’ll see the clam wild symbol appear in place of one of the removed win symbols during a cluster win. The wild coin symbol is directly linked to the Treasure Trail meter and appears in both the main game and the free spins feature.


Scrolls of 2x, 3x, 5x and 50x appear as multiplier symbols. If they land horizontally or vertically adjacent to a winning cluster, they’ll multiply your win by the value visible.

Treasure Trail Meter

The Treasure Trail meter, framing the game’s grid, is active all the time. Charge the meter with 3, 6, 9, and 12 consecutive wins, and you’ll unlock these special bonus features positioned around the grid: Anchor Drop: 1-3 random low-value symbols are picked and all instances of these symbols removed from the grid. Random Wilds: 4 to 8 wild coin symbols are placed anywhere on the reels. Mystery Chest: 2 to 16 medium and low value symbols are replaced with mystery symbols across the grid, which then transform into the same matching symbols. Cannon Blast: one symbol is chosen, followed by all medium and low value paying symbols in that row and reel removed except wilds and multiplier symbols.

Free Spins

Fill the meter fully with 15 charges, and you’ll find yourself on the cross marking the end of the trail and the start of the free spins bonus round. You’ll start with 9 free spins, and there’s also a possibility to earn an extra 2 before you start the round. In the free spins, you’ll earn 1 additional free spin with an extra 15 charged bars and 1 more spin for every 3 charged bars after that. Beyond the extra free spins, you’ll have the Mystery Overlay feature, activated with 5 mystery symbols appearing in the ‘+’ form in the centre of the grid. Mystery symbols will land on this pattern and transform into matching symbols on each free spin. If you happen to land any additional mystery symbols horizontally/vertically adjacent to the existing mystery symbols, they’ll become a part of the cluster, expanding the initial pattern until the free spins end.

Reef Raider Jackpot

NetEnt has left the jackpot out to make more room for the game’s juicy max potential of 8,500x your bet. To win, charge up the Treasure Trail meter to land free spins with mystery overlay symbols.

RTP and Volatility

According to the developer, Reef Raider is a high volatility game, so big wins are very possible here. The RTP appears to be a standard 96.02%.
