The mermaid is the wild symbol, she can land on reels two, three, four and five, and she will substitute for all of the other symbols, except for the scatter and bonus symbols, to help and form winning combinations.
The treasure chest is the scatter symbol and the pearl is the bonus symbol.
When at least six of the pearl bonus symbols land on the reels, the Fire Blaze Respin Feature is triggered. Each of the pearl symbols that lands will display a cash prize or Star icon. The triggering symbols are then held in place and three respins are awarded. Each un-held position then spins independently. If any more pearls land, then they too are held in place and the respin counter is reset to three. This process continues until all positions are filled with pearls or the respins run out.
After the respins are finished, the prize values shown on the pearls are awarded. If all positions contain a pearl then the Grand jackpot is awarded. Any held star icons will transform to award the Major, Minor or Mini jackpots and it is possible to win each of these multiple times in a single feature. The Grand, Major, Minor and Mini jackpots are worth 2000, 500, 100 and 20 times the bet respectively. The pearls can award payouts of 1, 2, 3, 4, 5, 10, 15 and 50 times the total bet.
When three scatter symbols land anywhere on the reels, six free spins are awarded. During the free spins, all wild symbols that land on the third reel will come with a payout multiplier of x2, x4, x8 or x16. Furthermore, the prize values that appear on the pearl symbols on the middle reel increase to 5, 10, 15 and 50 times the total bet. Best of all, the free spins can be retriggered indefinitely.
There is a top payout of 60x for landing five octopus symbols along a payline. The tortoise can payout up to 40x, the fish up to 30x, and the jellyfish up to 25x. All of the royal symbols offer payouts of up to 16x.
