What is Reef Raider and Who Developed It?

Reef Raider is an online slot game developed by NetEnt. This game features 7 reels and utilises the Cluster Pays™ mechanic for its payout structure. Players can place bets ranging from a minimum of £0.20 to a maximum of £4.00 per spin.

How Do You Play Reef Raider?

• Wins are awarded for clusters of 5 or more matching symbols connected horizontally or vertically.
• Multiple non-adjacent clusters of the same symbol are counted separately.
• The game supports wagers in both coins and cash. Bet values are adjusted by clicking the Bet Settings button and selecting either the coin value and bet level (when playing with coins) or the bet amount (when playing with cash).
• Your available balance, displayed as either cash or coins, is shown at all times.
• Payouts and winning combinations can be reviewed in the in-game Paytable, which updates its values dynamically according to the chosen bet.
• For each cluster win, the payout is calculated based on the Paytable and multiplied by any active multipliers.
• Only the highest win per cluster is paid, and wins from multiple clusters are added together.

What is the Avalanche™ Feature?

• Instead of spinning, symbols fall into place on the reels.
• When a cluster win occurs, the Avalanche™ feature is triggered.
• Symbols involved in the win explode and disappear, allowing new symbols to fall into the empty positions.
• The Avalanche™ sequence continues until no additional cluster wins are formed.

How Do the Wild Symbols Work?

• If a winning cluster contains at least three medium win or low win symbols, a Clam Wild symbol will replace one of these symbols after the win is evaluated and before the next Avalanche.
• Wild Coin symbols can appear during the main game and Free Spins when triggered by certain features.
• Both Wild Coin and Clam Wild symbols substitute for all symbols except Multiplier symbols.
• If a Wild Coin or Clam Wild symbol forms part of a winning cluster, it is removed with the cluster during the Avalanche.
• Wild Coin and Clam Wild symbols help form the highest possible winning cluster combination based on the Paytable.
• One Wild Coin or Clam Wild symbol can be involved in more than one winning cluster if those clusters are adjacent.
• Wild Coin and Clam Wild symbols only award wins when included with other symbols.

How Do Multiplier Symbols Function?

• Multiplier symbols multiply the win of any cluster to which they are horizontally or vertically adjacent, with values of x2, x3, x5, or x50.
• Multiplier symbols are not considered part of a winning cluster.
• A single Multiplier symbol can influence several cluster wins at once if it is next to multiple clusters.
• Multiplier symbols can appear anywhere on the reels in the main game, and in any position except those with Mystery Overlay in Free Spins.
• Only one Multiplier symbol can be present on the play area at a time.
• When a Multiplier symbol is adjacent to a winning cluster, it disappears from the play area during the Avalanche.

What Is the Treasure Trail Meter and How Does It Work?

• The Treasure Trail meter starts with 15 uncharged bars at the beginning of each round.
• Each time a Clam Wild symbol is removed in a cluster win, one bar is charged on the meter.
• A Clam Wild symbol can only charge one bar per play, even if involved in multiple winning clusters.
  • Charging 3 bars activates the Anchor Drop feature.
  • Charging 6 bars activates the Random Wilds feature.
  • Charging 9 bars activates the Mystery Chest feature.
  • Charging 12 bars activates the Cannon Blast feature.
• Features are triggered in the order they are won, after all Avalanches have finished.
• The meter resets to zero once all awarded features have been played, or when there are no more Clam Wild cluster wins.
• Every new round starts with the meter at zero charged bars.

What Are the Features Activated by the Treasure Trail?

Anchor Drop Feature

• Activated by charging 3 bars.
• Randomly selects 1 to 3 types of low win symbols and removes all matching symbols from the play area.
• Triggers the Avalanche™ feature afterwards.

Random Wilds Feature

• Activated by charging 6 bars.
• Randomly adds 4 to 8 Wild Coin symbols to the reels.
• Wild Coin symbols do not land on Clam Wild or Multiplier symbols during this feature.

Mystery Chest Feature

• Activated by charging 9 bars.
• Replaces 2 to 16 medium win or low win symbols with Mystery symbols.
• All Mystery symbols transform into the same type of low win or medium win symbol, never a mix.
• Mystery symbols may be placed anywhere except positions occupied by Wild Coin, Clam Wild, or Multiplier symbols.

Cannon Blast Feature

• Activated by charging 12 bars.
• Removes a randomly selected symbol and all medium win and low win symbols from its row and column.
• Clam Wild, Wild Coin, and Multiplier symbols are not removed by this feature.
• Any removed symbol may be randomly replaced by a Wild Coin symbol.
• Triggers the Avalanche™ feature afterwards.

How Are Free Spins and the Mystery Overlay Feature Triggered?

• Filling the Treasure Trail meter with 15 or more charged bars in the main game triggers Free Spins.
• Each extra set of 3 charged bars in the main game grants 2 additional Free Spins.
• During Free Spins, 15 charged bars award 1 more Free Spin, with every additional 3 bars granting another Free Spin.
• Free Spins begin once all currently awarded features have finished, with no Avalanches remaining.
• At the start of Free Spins, the Mystery Overlay feature introduces 5 Mystery symbols to the reels—1 in the centre and 4 adjacent (horizontally and vertically).
• These symbols are revealed to form a single type of low or medium win symbol in a cluster.
• The initial Mystery symbol positions do not change until Free Spins end.
• In each Free Spin, more Mystery symbols may appear at random. If these are next to the initial cluster, they join it and remain until Free Spins conclude.
• All Free Spins are played at the same bet as the round that triggered them.
• Free Spins finish when no spins remain. The game then returns to the main game, and the Treasure Trail meter is reset to zero.
• The total win from Free Spins is combined with winnings from the triggering round.

What Else Should Players Know?

• Procedures for handling unfinished game rounds and session timeouts are subject to the casino operator’s terms and conditions.
• If there is a malfunction of gaming hardware or software, all affected game bets are voided and refunded.
