This is a cluster pays slot machine, which means that there are no paylines.
A symbol is part of a cluster if it is horizontally or vertically adjacent to the same symbol.
Multiple clusters of the same symbol that are not adjacent to each other are paid out as separate clusters.
A Treasure Trail is placed around the reels in this game, consisting of 15 meter bars.
One meter bar will become charged each time a Clam Wild is removed from the reels as a result of a winning Cluster.
Depending on how many meter bars are charging, different features will be activated:
Number of Charging Meters
Meter bars can be filled while playing Free Spins.
If three or more low or medium-value symbols are involved in a winning cluster, a Clam Wild symbol will be added to the reels.
It will be added before the Avalanche and replace one of the removed low or medium-value symbols.
Between one and three low-value symbols will be chosen at random at the start of this feature.
All instances of the chosen symbol(s) will then be removed from the reels.
This feature sees four to eight Wild Coins added to random reel positions.
If triggered, between two and 16 low and medium-value symbols will be replaced with Mystery symbols.
All Mystery symbols will then be revealed and potential Cluster wins will be evaluated.
One symbol will be randomly selected at the start of the Cannon Blast feature.
That symbol, as well as all low and medium-value symbols in the same row and column, will be removed from the reels.
It's not possible for Clam Wilds, Wild Coins and Multiplier symbols to be removed during the round.
This feature can only trigger in the main game.
Activate it by achieving 15 or more charged meter bars.
For every extra three charged bars above 15, you will receive two more free spins.
Land another 15 charged bars during the feature to win an extra spin.
This feature ends when all free spins have been used.
The Mystery Overlay feature is in-play during Free Spins.
It sees five Mystery symbols added to the reels.
One will be placed in the center of the grid and four on the positions horizontally and vertically adjacent to it.
All Mystery symbols will then be revealed, guaranteeing a winning cluster comprising of low or medium-value symbols.
It's possible for additional Mystery symbols to be added to the reels on each free spin.
If one is placed on a position horizontally or vertically adjacent to the initial cluster of Mystery symbols, it will become part of the cluster and remain so until the end of Free Spins.
