4ThePlayer by Relax Gaming is back with another feature-rich release and this time they’re taking us straight into pirate territory with 4 Pirate Chests. And no, this isn’t just another pirate-themed slot game, this one is on a different level.
It’s a vibrant, high-energy slot packed with loot-filled reels, mystery symbols, and even a treasure chest mechanic that keeps players spinning for more wins. With a slick mix of free spins, buy features, and a fun sea-themed aesthetic, it’s designed to capture both casual players and seasoned spinners and it does a good job of doing just that.
Treasure Chest Mechanics Above the Reels
At first glance, the game grabs attention with its simple format of a 5×4 layout and vibrant pirate visuals. But when you look a little closer, you’ll notice the real star of the game — 4 chests sitting above the reels.
These chests slowly fill up with “Pieces of 8” as you spin. Once enough coins are collected in one of the chests, the chest triggers one of the game’s core features and this is where it gets really wild.
It’s a clever twist that we love. Instead of waiting for traditional scatters to trigger bonuses, the action here builds visibly over time. You can actually see how close you are to putting the game into overdrive. That anticipation makes every spin feel like it’s getting you closer to something bigger — because you are.
One key chest to keep your eye on is just above reel 2. When that fills up, it triggers the Pirate Plunder Free Spins. That’s when the pirates on the reels drop their disguises, revealing high-paying symbols and triggering the Mystery Pirate Pays feature far more often.
Mystery Symbols Keep the Wins Coming
The Mystery Pirate Pays feature is another big hook. When triggered, the game drops mystery symbols across the reels. These then transform into a single matching symbol, creating guaranteed wins. And unlike some slots that save this feature for bonus rounds, 4 Pirate Chests can unleash mystery symbols during the base game too so keep an eye out for those gems.
This adds some serious value to every spin you make. Even outside the free spins, we’ve noticed there’s always a chance for a screen full of matching icons which is especially true when the chest bonuses are close to triggering.
Two Buy Features for Instant Action
If you’re like us and the type of player who doesn’t want to wait around for bonus rounds to show up naturally, 4 Pirate Chests has you covered. It offers two buy options for you to get ahead of the action.
- Free Spins Buy — Instantly launch into Pirate Plunder Free Spins for 60x your bet.
- Mystery Pirate Pay Buy — For 100x your bet, you get to jump right into a 5-reel Mystery Pirate Pays feature.
Both options are priced competitively compared to similar features in other slots, but we must admit that they might be a bit steep for casual players. If you have the coins to back it, they’re great for those looking to test out the most exciting parts of the game without grinding through spins to get there.
Hit Frequency and Win Potential
On the numbers side of the game, 4 Pirate Chests holds its own as well. The RTP comes in at a solid 96.01%, and the hit frequency is an impressive 31.25%. That means almost 1 in 3 spins will give you some kind of win. That’s really not bad for a slot with mystery features and bonus modes.
The volatility is rated at medium-high, which we find offers a nice balance between steady payouts and the occasional big hit. During the free spins mode, the average win clocks in at around 21.88x your bet which is enough to make the bonus feel worthwhile without relying on extreme variance.
And for those gamers chasing the max payouts? The top win possible is 10,240x your bet, which puts it on par with some of the more aggressive slots on the market. So while it plays fair in the base game, the potential for explosive wins is still there when the right features line up on the reels.
Visuals, Symbols, and Atmosphere
The visual style goes all-in on the pirate theme which makes it totally immersive.
You’ve got the skulls, compasses, sabers, pirate captains, and, of course, treasure galore. It’s almost like that scene from the Goonies when they find One-Eyed Willie’s treasure on the ship.
The background shows a moonlit tropical island with a skeleton-shaped cliff face and piles of gold, which might feel like it’s a bit cliche, but nonetheless fitting. It’s not just a static backdrop either — the animated touches and flowing graphics give the game a bit more energy.
Above the reels, the chests themselves are animated and change color depending on how close they are to triggering. It’s a small detail that most developers would otherwise overlook, but it helps guide the player’s focus and builds tension with every coin collected.
And yes, there’s a parrot perched above the reels. No pirate slot would be complete without one.
Accessibility and Betting Range
Whether you’re more of a cautious bettor or like to go full cannon-blast with the GC and SC, 4 Pirate Chests has a wide betting range. Minimum bets start at 0.10 SC, and you can go up to 10 SC per spin. That makes it perfect for sweepstakes-style gameplay whether you’re grinding out spins or shooting for the stars.
This kind of flexibility also pairs well with the game’s feature-buy options. You can try the game at a lower risk before deciding if it’s worth your time and pushing for bigger bonuses.
Ready To Get Your Slice of the Pirate’s Treasure in 4 Pirates Chests?
4 Pirate Chests pulls together what we feel is a well-balanced mix of traditional slot mechanics and creative features. The game’s treasure chest system adds long-term engagement which is a must with so many options on the table.
The mystery symbols shake up the base game, and the buy features give players full control over how they experience the action. The choice is yours on how you want to move forward.
On top of that, 4ThePlayer has a solid track record with innovative slots, and this one continues the trend. It’s easy to pick up and start playing, definitely rewarding to play, and manages to avoid gimmicks by building features that actually matter opposed to fluff.
So whether you’re here for the mystery wins, the pirate theme, or the promise of buried treasure, this one’s worth hoisting the sails for.
