Reels are encircled by a ‘Treasure Trail’ consisting of 15 ‘meter bars’. These bars are initially uncharged, but each time a Clam Wild is removed from the play area because of a cluster win, 1 bar of the Treasure Trail meter is charged. The Reef Raider -- a crazy pirate crustacean searching for treasure -- moves along the treasure trail as its meter bars get charged.
Features lie at each of the four points along the Treasure Trail and are activated when the Reef Raider arrives at that point along the track. Features include the Anchor Drop Feature, Random Wilds Feature, Mystery Chest Feature, and the Canon Blast Feature. 15 or more charged Treasure Trail meter bars triggers Free Spins.
