Reef Raider Game Highlights
The Reef Raider slot game is a Cluster Pays NetEnt creation, which means you generate wins by creating clusters/groups of at least five matching symbols on the grid. This is a highlight because it gives you many more ways to win. Throw in the avalanche mechanic, and it’s easy to see why this online game is one of the best online slots for real money.
The Treasure Trail meter is another perk, showering you with riches in the form of gameplay perks as you fill it, from random wilds to the cannon blast where a cannon blasts away a symbol and others in its row and column, with the potential for wild coins to appear in their place.

How To Play Reef Raider
Start by reading through the game’s rules and paytable before placing your bet. Reef Raider has a broad betting range, from as little as $0.20 to as much as $100 per spin. Once you’re happy with your wager, go ahead and click the spin button to get the reels moving and potentially create your first cluster. There’s also an autospin function if you’d prefer to play hands-free.
Reef Raider Game Features
This online slot is simply swimming in features. Here’s an overview.
The avalanche feature is the core mechanic of the Reef Raider slot. When you form a winning cluster (a group of adjacent matching symbols), those symbols explode and disappear, making way for new symbols to fall in and potentially create new winning clusters. This avalanche effect continues until no new winning clusters are formed.
This top online casino slot also has two separate wilds. The clam wild only pops up after a winning cluster that includes at least three medium- or low-win symbols. It then replaces one of those removed symbols before the avalanche happens, increasing your chances of further wins. Then there’s the wild coin, which appears randomly during the base game, the free spins slot bonus, the Random Wilds feature, and the Cannon Blast feature (more about these below). It can substitute for any symbol except the multiplier to help you create those winning combos.
Speaking of multiplier symbols, these can appear anywhere on the reels during the base game and in free spins, except on spots occupied by mystery overlay symbols (another feature in free spins, explained below). Only one multiplier symbol can appear at a time, multiplying the payout of any winning clusters it’s directly touching (horizontally or vertically). The multiplier values can be 2x, 3x, 5x, or even 50x.
While playing, you’ll also notice the Treasure Trail meter on the screen — a progress bar that fills up each time a clam wild forms part of a winning cluster. As the meter fills, it unlocks exciting features along the way:
- 3 BARs = Anchor drop: Some low-paying symbols are removed, potentially leading to bigger wins.
- 6 BARs = Random wilds: Up to eight wild coin symbols are randomly placed on the reels.
- 9 BARs = Mystery chest: Up to 16 symbols are replaced with mystery symbols revealing identical symbols, increasing the chance of clusters forming.
- 12 BARs = Cannon blast: A random symbol and others in its row and column are removed and potentially replaced with wild coins.
Reef Raider Bonuses and Jackpots
Once the Treasure Trail meter reaches 15 bars or more, you’ll activate the free spins slot bonus and get nine free spins, while every additional three bars beyond that will award you two extra free spins.
During this bonus round, the Treasure Trail meter continues to fill up. So, if you charge it to 15 bars again, you get one extra free spin, and each additional three bars gets you another freebie.
The Mystery Overlay feature promises guaranteed wins and is exclusive to the free spins slot bonus:
- Initial cluster: Five mystery symbols appear in a cross-like pattern in the center of the reels and become sticky for the entire bonus round. These symbols are then revealed to all be the same type of low-win or medium-win symbol, creating a winning cluster right from the start.
- Expanding cluster: More mystery symbols can randomly appear on the reels with each free spin. If they land next to the existing cluster, they become part of it and reveal the same symbol, potentially creating even bigger wins.
How To Win Reef Raider
As with most slots online, the goal is to create winning combos of matching symbols. But Reef Raider works differently because, rather than creating combos on paylines, you need to create clusters of five or more of the same symbols to score a win. A symbol is part of a cluster if it’s horizontally or vertically adjacent to the same symbol, and multiple clusters of the same symbol that aren’t adjacent to each other pay as separate clusters.
Reef Raider Graphics and Design
Many will agree that Reef Raider is one of the best NetEnt slots (a revered slot software provider at BetMGM) not just because of its abundant features but also because of its graphics. The slot takes you underwater, where you meet a cartoon-style pirate crab (complete with a golden hook and an eyepatch) who’s dead set on unearthing as much treasure as possible. The grid is surrounded by colorful coral, pebbles, and underwater plants.
Reef Raider Symbols
Gems and shells are the main symbols in the Reef Raider slot and they pay out according to how many you collect in a cluster. The red diamond is the most profitable, giving you 2x your bet for a cluster of five and up to 3,000x your bet for a cluster of 25–49. The pink gem pays up to 1,000x your bet, the orange gem up to 60x, while the green gem pays up to 50x. The purple shell pays up to 45x, the blue shell up to 40x, the yellow shell up to 35x, and the green shell up to 30x.
