4 Pirate Chests Review: Skull Coins, Mystery Pays and Free Spins
4 Pirate Chests at a Glance
Four chests above the reels organise the action in 4 Pirate Chests. The one over reel two is linked to Free Spins, while the other three lead to Mystery Pirate Pays. Skull Coins connect the base game to these features through 4ThePlayer’s BOOMPOTS system. The result is a pirate slot with two different bonus directions, rather than four unrelated jackpot meters.

Features and Gameplay
Follow the Chest Positions
The chests sit above reels two to five. The reel-two chest starts Pirate Plunder Free Spins. The chests above reels three, four and five are associated with Mystery Pirate Pays. Their position therefore tells you which kind of bonus is involved.
Skull Coins feed the BOOMPOTS presentation. The studio says any coin can trigger the feature and a chest can award its bonus. Watching a chest fill is part of the visual sequence, but it is not a reason to assume that a particular number of extra paid spins must finish it.
Mystery Pirate Pays and the Undead Crew
Mystery Pirate Pays adds random mystery symbols to the reels. It changes the symbol result on the screen, rather than simply awarding a package of ordinary Free Spins. The supplier also offers a separate purchase option for a five-reel version of this feature.
Pirate Plunder follows a different route. The pirates reveal their undead forms during Free Spins, and BOOMPOTS awards occur more frequently in that mode. These are the two feature styles worth comparing in the demo before deciding whether the game suits you.
Ways, Versions and Feature Purchases
The game uses 1,024 ways to win. Ways are not individually selectable paylines. The stake display and paytable explain how a qualifying combination is evaluated, so comparing the ways count with a twenty-line slot on its own is not especially useful.
4ThePlayer lists both 94% and 96% RTP versions, along with configurations for Germany. Its own statistics identify high volatility and a 10,240x maximum. A casino’s selected version matters more than a quoted headline from another review.
Two purchase modes provide access to Free Spins or five-reel Mystery Pirate Pays. Availability varies by market. Each has a separate displayed price, and a purchased bonus can return less than it costs.
Our View of 4 Pirate Chests
The positional chest design is the strongest part of the game. Once you know which chest controls which bonus, it is easier to follow the action without remembering a long list of special symbols.
It suits players who enjoy collection-style presentations and two distinct feature modes. Anyone wanting a simple fruit-machine spin will have more to learn here. The high-volatility rating is also worth weighing before choosing a stake.
