How to Play

Surrounded by colorful coral reefs, the 7-reel, the 7-row playing field is framed by segments that create a Treasure Trail. Consecutive Avalanche wins move the pirate crab with a black eyepatch and a gold hook instead of a claw along this path, activating up to 4 modifiers along the way, as well as an exciting Bonus Round at the end. You win when you create clusters of 5 or more matching symbols anywhere on the grid. You can bet from €0.20 to €100.

To start this fun underwater adventure all you need is:

  • Open this new slot machine at your chosen casino
  • Read the rules and see the payouts for combinations
  • Choose a bet in the menu below: from €0.20 to €100
  • Set the reels in motion and have fun!

Reef Raider RTP and Volatility

8.8 
Medium volatility and 96.1% RTP.
This slot is on your side as it comes not only with Avalanche features but also medium volatility. This means that the prize combinations here are created more often than in high-risk games and still bring large payouts. As for the theoretical return, it is 96.1%, which is slightly above the industry average. In general, the game has a good mathematical model for both casual and experienced players.

Theme

8 

We like how this slot pays homage to some of NetEnt's earlier Cluster Pays classic slots, and it's a great alternative for those who want a more light-hearted action in this genre. Surrounded by colorful coral reefs, the playing field is framed by segments that make up the Treasure Trail. The crab pirate with a black eyepatch walking around the grid is pretty adorable, and the 4 modifiers come with some fun animations, even if their impact isn't always strong. Overall, Reef Raider looks good, with quality graphics and a nice cartoon style.

Now let's look at the paytable. Red, pink, orange, and green gems are medium win symbols. Purple, blue, yellow, and green shells are low win symbols. Symbols with numbers are multipliers, the shell with the letter "W" is the Claim Wild and the Coin with the letter "W" is the Wild Coin.

Bonus Rounds & Free Spins

7.9 

Modifiers

On the left side of the playing field is a Pirate Crab with a black eye patch. Consecutive Avalanche wins bombard special segments, changing their color from gray to pink. This is Treasure Trail progression, and every 3rd win in a row allows the crab to go to the next modifier trigger:

  • Anchor Drop: Anchors drop onto the playing field and remove 1 randomly selected type of low-paying symbol
  • Random Wilds: Randomly adds 4-8 Wild symbols to the grid
  • Mystery Chest: Turns 2-16 symbols into Mystery Chests and they all transform into a randomly selected matching symbol
  • Cannon Blast: removes all randomly selected pay symbols from a row and column

Bonus Round

Once you have loaded at least 15 Treasure Trail segments in the base game, the crab will reach its final destination and this will trigger the Bonus Round with a minimum of 9 free spins. Each additionally charged segment over 15 triggers 2 extra free spins on top of the original 9.
Reef Raider - free spins

During the bonus round, you win 1 Extra Free Spin for charging 15 segments, plus 1 Extra Free Spin beyond that for every 3 segments charged above the minimum of 15.

The Pirate Crab will still walk the Treasure Trail to activate the same modifiers as in the base game. You will see the Mystery Overlay pattern below the symbols forming a cross in the center center of the playing field. Mystery symbols (Chests) land on Overlay positions on every spin and always turn into the same corresponding symbol.

Regular Mystery symbols can also land. This creates new Overlay positions if even 1 symbol lands next to the original overlay template. Whichever overlay template you get, it stays in place for the duration of the bonus round.

Reef Raider Demo play

By trying the game for free, you will be able to understand what you should expect from it in the paid version. Luckily, you can try this slot machine for free! The demo version allows you to spin the Reef Raider reels while making non-real money bets. This version is available to any player, since no registration is required to use it. There is also no time limit, and if the provided amount of "fun" coins is used up, it will be enough just to reload the page with the slot.

Max Win

7 
Win up to 8,500x the bet.
The maximum win in this slot machine is 8,500x the bet. This is a big max win potential for a medium risk game and to unleash it you need to activate the Bonus Round with free spins, modifiers, and also Mystery Overlay symbols. Good luck!

Overall Rating

7.9

Reef Raider pays tribute to some of the Swedish giant's earlier Cluster Pays slots and is a great alternative for those who want more fun and lighthearted action in the genre. The protagonist, a pirate crab with an eye patch, walks around the screen and looks very cute and the 4 modifiers are accompanied by funny animations, even if their influence is not always very strong.

The Bonus Round may seem difficult for you to trigger as 15 consecutive avalanches is not something that happens very often in this game. However, you will be able to perform such "miracles" on a regular basis thanks to a well balanced math model to win up to 8,500x the bet which is a solid potential for a medium volatility release.
