How to Play

Spinning the reels of Reef Raider is easy to do and bets per spin start from as little as 20p and rises to a maximum of £100 per spin. Click on the coin button under the reels to set your bet per spin and then hit the blue spin button to send the reels tumbling.

As this is a cluster pays slot game, winning combos are formed by landing five or matching symbols in a cluster.

The symbols on the reels of this game are:

  • Green shell
  • Blue shell
  • Purple shell
  • Yellow shell
  • Orange gem
  • Pink gem
  • Green gem
  • Red gem
  • Wild


In the base game, the highest value symbol on the reels is the red gem which awards 150x your stake for a cluster of 25 or more symbols on the reels. Players can win up to 8,500x their total stake with the multiplier feature.

Special Features

Reef Raider has five special features including an avalanche feature, wilds, multipliers, the treasure trail features and the free spins bonus round.

The popular avalanche feature is present in this slot game where each time a winning combo is formed, the symbols in that combo are removed from the reels to make way for new symbols to take their place and potentially form new winning combinations. This process carries on until there are no new winning combinations formed.

If a multiplier symbols lands next to a winning combo, either on top, below or to its side, it will multiply your win by 2x, 3x 5x or 50x.

There are two wild symbols in Reef Raider. The first is the clam wild and the second is the coin wild.

A highlight of this game is the treasure trail feature which is triggered by the avalanche feature. When an avalanche is activated, it will power up the treasure trail meter around the reels. There are four bonus features you can trigger as part of the treasure trail:

  • Anchor drop feature – three avalanche wins will trigger this feature where between one and three low value symbols will be randomly chosen and removed from the reels, followed by another avalanche
  • Random wilds feature – six avalanche wins will trigger this feature where four to eight coin wild symbols will be added to the reels and will replace other symbols to help form new winning combos with the exception of any multiplier symbols
  • Mystery chest feature – nine avalanche wins will trigger this feature where between two and 16 low value symbols will be replaced by a mystery symbol
  • Cannon blast feature – 12 avalanche wins will trigger this feature where one symbol is removed and all other low to medium value symbols on the same row and reel will be removed, followed by an avalanche

The free spins round is also triggered by the treasure trail meter and players will receive nine free spins. As you play the free spins, one mystery symbol will be placed in the middle of the grid and another four will be placed around it. These symbols will turn into a matching symbol with every free spin and more mystery symbols can be locked in place and added to this cluster as you play. The treasure trail meter can still be filled during this round to award players additional free spins.
