Agent of Hearts Slot Review
Play’n GO have established themselves as masters of the grid slot format, and Agent of Hearts stands as a compelling example of their expertise. Released in August 2021, this Wonderland-themed slot brings Lewis Carroll’s timeless characters back for another adventure. The game’s visual presentation brings the Wonderland setting to life through high-quality artwork – expect to see purple trees, floating rocks, teapots, cups, and cards creating an immersive magical environment that immediately sets the tone for what’s to come.
Base Game & Features
Agent of Hearts uses a distinctive 7-7-5-5-5-7-7 grid layout with cluster pays mechanics. To land a winning combination, you’ll need five or more matching symbols connected horizontally and/or vertically. Once a winning cluster forms, the cascade mechanic kicks in – winning symbols are removed and new symbols drop from the top, continuing as long as new winning clusters form. This cascade mechanic creates considerable excitement to base gameplay, allowing multiple wins from a single spin.
The base game benefits from two key features that keep things engaging. Random Heart Wilds can appear on non-winning spins, with 4 to 7 wild symbols placed randomly to boost your chances of landing a winner. These wilds provide unpredictable boosts during base play that can turn a losing spin into something more promising. Combined with the cascading reels, there’s plenty of action happening before you even consider the bonus features.
Agent Collection Feature & Bonus Mechanics
The heart of Agent of Hearts’ bonus offering is the Agent Collection Feature. Collect 6 agent symbols during play, and you’ll unlock special agent features that transform the gameplay. There are four distinct agents, each offering their own symbol-removal or transformation mechanics:
- Cupcake Splat (Dormouse) – removes or transforms symbols
- Smokin’ Phat (Caterpillar) – removes or transforms symbols
- Grinning Cat (Cheshire Cat) – removes or transforms symbols
- Mad Hatter (Mad Hatter) – removes or transforms symbols
Varied visual presentations and activation patterns create distinct gameplay moments, and the Wonderland character integration feels thematically natural. That said, whilst each agent brings its own visual flair, they fundamentally perform similar symbol-removal operations despite their differentiation.
Queen’s Heart Free Spins – The Big Feature
Where Agent of Hearts really makes its mark is the Queen’s Heart Free Spins feature. To trigger this bonus, you need to collect 3 golden key scatter symbols on a single paid spin or through cascades. Once activated, you receive 1 maximised free spin – but it’s a special one.
During your Queen’s Heart free spin, you’ll experience all 4 Agent Features playing out in sequence, alongside 4-7 Random Heart Wilds and a 3×2 Mega Wild. The free spin itself is non-retriggerable, meaning this is your one shot at the big win. This single maximised free spin format creates genuine tension with all gameplay momentum concentrated into one crucial moment. It represents a high-volatility climax moment that’s quite different from the extended bonus rounds you’ll find in many other slots.
The design philosophy prioritises dramatic peak moments over extended bonus rounds. Some players love this intensity; others who are accustomed to playing through multiple free spins may find it less satisfying. Either way, the potential is genuine – with a maximum win of 5,262x your stake, there’s plenty to play for when that Queen’s Heart appears.

Our Honest Verdict
Agent of Hearts is a well-crafted, thematically immersive slot that’s genuinely entertaining. The Wonderland aesthetic is beautifully executed, and the combination of cascading reels, Random Heart Wilds, and agent features creates plenty of action during base gameplay. The Queen’s Heart free spin, when it finally appears, delivers that peak moment of high-volatility tension that many players crave.
However, it’s worth being honest about what Agent of Hearts isn’t. It doesn’t represent a mechanical breakthrough in the grid slot space – the cascade mechanic remains industry-standard. The four agent features, whilst visually differentiated, fundamentally perform similar symbol-removal operations, and this sameness can feel repetitive during extended base game sessions. If you’re the type of player who loves extended bonus rounds with multiple free spins, the single maximised free spin format won’t satisfy in the same way.
That said, Agent of Hearts will impress fans of Play’n GO’s Rabbit Hole Riches series. If you enjoy high-volatility gameplay with engaging features and appreciate strong thematic execution, there’s plenty to like here. The combination of a solid 96.25% RTP, a respectable 5,262x maximum win, and a genuinely immersive Wonderland presentation make this a credible choice for players seeking high-volatility action with meaningful stakes.
Overall Verdict: 7.5/10
Best for: Players who enjoy high-volatility slots with engaging features and strong thematic presentation. Fans of Play’n GO’s grid slot expertise and the Rabbit Hole Riches series will find this title appealing.
Skip if: You prefer low-to-medium volatility slots or extended bonus rounds with multiple free spins. If repetitive symbol-removal mechanics frustrate you, the Agent Features might feel underwhelming.
The Bottom Line: Agent of Hearts is a solid grid slot from a developer who knows what they’re doing. It’s not groundbreaking, but it’s well-made, visually impressive, and offers genuine entertainment value. For high-volatility players, that’s enough reason to give it a spin.
