Theme and Design
The game has a dark, playful pirate mood. The pirates are undead swashbucklers, and they change form during the free spins. Skull Coins replace the traditional gold coins, which gives the game a fresh look.
Four treasure chests sit above reels 2 to 5. They fill up with Skull Coins as you play. Each chest links to its own bonus, so the top of the screen always matters. This is a smart design touch. It gives you a goal to watch while you spin.
RTP, Volatility and Max Win
The slot has a 96% RTP in its main setting. A 94% version and some regional versions are also listed. RTP is a long term measure, so it does not predict a short session. Check the info screen at your casino to see which version you get.
Volatility is high. As a result, expect uneven results. Some sessions will be quiet, and others can deliver a strong bonus. The maximum win is 10,240x your bet.
The minimum bet is 0.10, so it is easy to test the game with small stakes.
4 Pirate Chests Bonus Features
The features all connect to the Skull Coins and the chests above the reels.
BOOMPOTS
BOOMPOTS is the signature feature. Any coin can trigger it. Any treasure chest can also award its bonus. This keeps every spin alive, because a trigger can come from several places.
Mystery Pirate Pays
Mystery Pirate Pays starts when you fill the chests above reels 3, 4 or 5. Random mystery symbols are then added to the reels. These symbols reveal into matching icons. As a result, they can create strong win combinations.
Pirate Plunder Free Spins
The chest above reel 2 triggers the Pirate Plunder Free Spins. During the round, the pirates transform. BOOMPOTS also awards more often. That makes this the most exciting part of the game.
Buy Features
The slot has two buy modes. One buys the Free Spins directly. The other guarantees a 5-reel Mystery Pirate Pays feature. Buy options are not available in every market, so check your casino.
