How Reef Raider works

The cute crab who stars in this game can be found in a rock pool, of course! This rock pool holds a grid of symbols, measuring 7x7 spaces. Spinning the slot fills the grid with seashells and gems - to win, you'll need to make a cluster of five or more symbols, joined horizontally or vertically to each other. Those symbols include green, yellow, purple and blue seashells, and green, orange, pink and red gems. There are also multipliers on the board, worth 2x, 3x, 5x and 50x, which are activated if they land horizontally or vertically adjacent to a winning cluster.

Every winning cluster will explode and disappear from the grid, leaving behind a wild clam symbol. Remaining symbols will drop down to fill the spaces, and new symbols fall from the top to replace the missing ones. Multiple wins can be formed this way, through the chain reaction of the avalanche. If a win is made that contains a wild clam, it will move the pirate crab one space per wild along the treasure trail!

Treasure Trail Bonuses

Every three winning wilds collected will activate a special feature. These are applied one at a time, paying any wins they make - and potentially moving the crab further along the trail to grab even more features!

• 3 spaces = Anchor Drop, which removes low paying symbols

• 6 spaces = Random Wilds, shown as golden coins on the reels

• 9 spaces = Mystery Chest, a transforming cluster of symbols

• 12 spaces = Cannon Blast, which clears one row and one column of symbols

Get 15 or more wild wins to reach the end of the trail, and activate the free spins bonus!

Free Spins Feature

Nine free games are awarded for hitting the X on the trail, plus two extra spins for every additional three spaces filled. During free spins, a block of five spaces appears in the centre of the reels, filled with mystery chests that transform to make a winning cluster. This block is locked in place throughout the round, and any extra mystery chests that land adjacent to it will cause it to expand!

Gameplay is matched to the bonus round, so wild clam wins will continue to light up the trail and activate the bonus features. New spins can be won as well, with 15 or more wilds collected.
