4 Pirate Chests is a high-octane treasure hunt from 4ThePlayer, taking the popular Hold & Win genre and adding their own creative spin—including their signature BIG REEL Portrait Mode™ for vertical mobile players and a dynamic bonus volatility selector.
The base game runs on a 6×4 grid with 4,096 ways to win, and it’s built around golden chest symbols that show up with cash values, multipliers, or even Mini, Major, and Mega prizes. These symbols are collected only during the Chest Bonus, which is triggered by landing 3 or more scatter symbols.
Once inside, you’ll be offered 4 Deals—a unique twist where you pick your bonus volatility:
- Low Risk – More spins, lower chest values
- Balanced – Standard setup
- High Risk – Fewer spins, higher chest values
- Random – Any of the above, chosen for you
During the bonus, only cash symbols, jackpots, and special chests can land, making each spin full of anticipation. The bonus ends only when no chests land for three spins, and some versions offer Chest Boosts that raise the minimum value of symbols in play.
The max win is a massive x15,000, making this one of 4ThePlayer’s most generous slots to date. RTP is officially listed at 96.00%, but alternative versions can drop as low as 94%, 92%, or even 90% depending on the operator—check the paytable before playing.
Visually, 4 Pirate Chests delivers polished pirate aesthetics with high-detail characters, ocean-blue reel frames, and thunderous sound design that amps up the action. It plays equally well on desktop and mobile, and BIG REEL mode on smartphones is especially immersive.
