Reef Rider is a NetEnt video slot that came out in 2021. Its backdrop is set at the bottom of a coral reef, where a pirate crab has hidden its treasure, which you’re tasked with uncovering.
Colourful seashells and gemstones populate the reels of the Reef Raider slot. Locked chests assume the role of mystery symbols, while clams and golden coins with the letter W are wild symbols.
Reef Raider Slot Basics
The Reef Raider slot uses a 7×7 grid, with cluster wins replacing traditional paylines. Betting begins at £0.20 per spin and caps at £100, and the Reef Raider slot’s maximum reward is 8,500x your total wager. Earning a win requires you to land five or more identical icons in a cluster.

Rubies are the highest-paying icons in the Reef Raider slot, awarding £100 for five icons, £125 for six, £150 for seven, £250 for eight, £300 for nine, £500 for between 10 and 11 symbols, £750 for between 12 and 14 icons, £1,250 for between 15 and 17 symbols, £2,500 for between 18 and 20 icons, £5,000 for between 21 and 24 symbols, and £15,000 for 25 or more icons. After this, pink hexagonal gems pay £5,000, square orange gems pay £3,000, green triangle gems pay £2,500, purple seashells pay £2,250, blue seashells pay £2,000, beige seashells pay £1,750, and green seashells pay £1,500.
Reef Raider Slot RTP And Volatility
The Reef Raider slot comes with high variance, which means that the wins you make while playing the casino game are going to be larger in size but paid infrequently. Meanwhile, the slot’s RTP (Return to player rate) is 96.1%, which is around the average for most video slots. The RTP tells you the percentage of all wagered funds that are returned to players over a long period of time and numerous users.
Special Features
The Reef Raider slot comes with numerous special features, including an avalanche feature, where all wins explode and disappear, allowing existing symbols to fall into their position. New symbols fall from above, and these icons can all form additional wins, continuing the avalanche reaction until there are no more wins and a new spin is required.
There are two wild icons in the slot: clam wilds and wild coins. When a cluster of at least three icons is removed from the reels, a clam wild icon is added in a random position. Meanwhile, wild coin icons appear on the reels in the main game or in the free spins when the random wilds or cannon blast features are triggered. Wild coin and claim wild symbols both substitute for all symbols except multiplier icons to help make more wins. If a wild coin or clam wild icon helps form a winning combination, it’s removed from the play area along with the rest of the winning cluster.
A multiplier symbol adjacent to a winning cluster multiplies that win by its value of either 2x, 3x, 5x or 50x. Multiplier symbols are not considered a part of the winning cluster, but they can apply to several clusters at the same time. Multiplier symbols can appear anywhere on the reels in the main game and anywhere in the free spins mode except for positions with mystery overlay symbols.
The slot comes with a treasure trail meter of 15 uncharged bars. Whenever a clam wild icon is removed from the playing grid, one bar of the trail meter is charged. Three charges trigger the anchor drop feature, six bars award the random wild feature, nine bars trigger the mystery chest feature, and 12 bars trigger the cannon blast feature. The features only occur when there are no more wins from avalanche reactions, and the features are played in the order they were triggered. The treasure trail meter resets once all features have been triggered.
When the anchor drop feature is triggered, up to three low win symbols are randomly chosen and removed from the playing area, triggering an avalanche reaction. Meanwhile, the random wilds feature awards between four and eight wild coin symbols to the reels.
When the mystery chest feature is triggered, between two and 16 medium win and low win symbols are replaced with mystery icons that reveal the same type of low or medium win symbol to make a winning cluster. Finally, the cannon blast feature removes a random symbol from the reels along with all medium and low win icons in the same row and column as the selected symbol.
In the main game, 15 or more charged treasure trail meter bars trigger the free spins mode with nine spins, and every extra three charged bars award two extra spins. In the free spins mode, 15 charged bars award one free spin each, and an extra spin for every additional three charged bars. The free spins mode starts when all activated features have been played and there are no more avalanche reactions.
When you start the free spins mode, the mystery overlay feature is triggered and five mystery symbols appear on the reels. Mystery symbols are revealed to form a winning cluster of low or medium win symbols. Mystery symbols can randomly appear on the reels on every spin, and the feature ends when the free spin counter reaches zero.
