If you have ever wanted to chase treasure without a five-reel storm of features and paylines, Pirate Coins from Tom Horn Gaming is the ideal stripped-down, single-payline swashbuckler. Built in partnership with Twin Win Games, this 3x3, high-volatility title trades traditional symbols and base game payouts for a fast-paced, feature-loaded bonus system. There is just one way to win: land three coins in the middle row and trigger the Hold & Win-style bonus game. From there, it is all about sticky coins, multipliers, mystery jackpots, and the chase for a full board and that 500x Grand Jackpot. With a max win of 2,676x and an RTP that hovers just below average, Pirate Coins might not appeal to everyone—but for players who enjoy focused, high-risk gameplay with big payout potential, this one undeniably has treasure buried in every spin.
Pirate Coins plays out on a minimalist 3x3 grid with just 1 active payline. What this means is that the action is laser-focused on the middle row. You win nothing in the base game unless you hit three coin symbols across that single line. When you do, it will trigger the bonus feature. And this is where all the real action takes place.
The bet range is wide enough to accommodate most play styles, starting at £0.50 and stretching all the way up to £100 per spin.
As for the RTP, Pirate Coins comes in two versions—94.05% and 94.33%, depending on your casino. That is well below the industry’s preferred benchmark of 96%, which might be a sticking point for more stats-conscious players. But the high volatility helps balance that out by aiming bigger with less frequent hits.
The maximum win? A modest but respectable 2,676x your stake. Essentially, this slot game is more of a sharp burst than a slow burn jackpot marathon.

There are no card ranks or generic filler icons in Pirate Coins. Every symbol has a specific function, with all payouts and features stemming from the bonus game. Visually, the slot has a bright, cartoon-style pirate theme—golden coins, sandy beaches, treasure chests lit by torchlight, etc.
It is clean, modern, and quite polished for a 3x3 release, staying on brand with Twin Win Games’ recent output.
Audio-wise, the music is a looping pirate-style jingle with twinkling bells and the occasional splash of sound effects to signal a bonus trigger or coin land. It is not invasive, and it does a decent job of keeping the atmosphere alive without being repetitive.
As for symbols:
Naturally, there is no paytable in this slot game. No standard Wilds, no regular Scatter system. The game just has a functional, coin-driven gameplay focused on high-risk, high-reward momentum.
Pirate Coins is built using HTML5, meaning it performs just as well on mobile devices as it does on desktop. The 3x3 grid fits naturally on small screens, and the minimalist layout makes it easy to follow what is happening (even during the chaos of the bonus game).
All buttons are touch-friendly and responsive, and there is no unnecessary clutter. Whether you are spinning on an iPhone, Android, or tablet, the visuals stay sharp and the gameplay smooth.
This is a game that feels right at home in portrait mode during quick mobile sessions.
Pirate Coins may only have one payline and one feature trigger, but the bonus game is where you see its full potential. This is a Hold & Win-style feature with a variety of coin symbols and modifiers that can lead to some intense sessions.
The only way to trigger wins is by landing 3 coin symbols across the middle row—that starts everything.
Triggered by landing 3 coin symbols on the central row. The bonus starts with 3 respins, and any new coin, jackpot, or special symbol that lands resets the counter. The round ends either when all positions are filled or no new symbols land. The cash value of all coins on the grid is added up and awarded.
This is a random event during the bonus game. If a Chest symbol lands, it applies a multiplier to one or more coin values on the board. These multipliers can give a much-needed boost during slow starts.
The Grab symbol is the golden ticket. When it lands, it instantly collects all visible coin values and jackpot prizes on the screen and adds them to your total win.
These coins offer higher value—between 5x and 9x—and stay locked in place when they land. They massively increase your odds of reaching the Grand Jackpot, and you cannot ignore them if you are going for the full grid.
Three jackpot symbols can appear:
Land one during the bonus, and it gets added to your total instantly. Multiple jackpot coins can be collected in a single round if you are lucky.
This is the top prize. Fill all nine positions on the grid and win an additional 500x on top of whatever coins and jackpots you have collected. This is the max payout mechanic that pushes the total win up to 2,676x.
For 33x your bet, you can skip the base game and head straight into the Hold & Win bonus feature. This gives you a clean shot at climbing toward jackpots and high-value coins, but the risk-reward balance remains.
There is a weird joy in spinning a 3x3 slot where nothing happens for five minutes—then, out of nowhere, you are in a gold rush with coins landing, grab symbols firing, and multipliers raining down.
Pirate Coins has a strangely hypnotic rhythm to it, and that rhythm only breaks when the Dog-like lack of base game wins starts to wear thin. But when the bonus game kicks off, things can get chaotic fast (in a good way).
The volatility is real, the ceiling is modest but not laughable, and the risk always feels like it might just be worth it if that next coin lands. It is not perfect, but it has the charm.
