Introduction

Agent of Hearts presents a 7-7-5-5-5-7-7 slot layout with Cluster Wins of 5+ matching symbols. The game centres around unlocking the Queen’s Heart with 4 Agent features to help you along the way. The Agent features are the key to an increasing win pot and feature heavily throughout the game.

Agent of Hearts Theme, Graphics & Soundtrack

Based loosely on the Alice in Wonderland theme, Agent of Hearts features some character favourites like the Mad Hatter, the Cheshire Cat, the Caterpillar and the Dormouse, alongside some green, purple, blue and yellow gems.

Along the way our magical characters will throw in some features of their own and you can expect to meet some Random Heart Wilds too. The graphics are interactive and a delight. The soundtrack is fitting with the magical theme and varies on different actions performed.

A Guide To Playing Agent of Hearts

Agent of Hearts is a simplistic game to play with plenty of interactive bonus features to keep you occupied. For a regular win, all you need to do is match 5 or more symbols in a cluster, as long as they are touching horizontally and/or vertically, you have a win.

Betting Range and Prizes

The betting range for Agent of Hearts is £0.20 to £100 per spin with a potential maximum win of 5,262.5x. The highest paying symbols are the feature characters with the Mad Hatter rewarding £100,000 for landing 15+ matching symbols on a maximum bet.

Random Heart Wilds

Heart Wilds will substitute for all other symbols except the Key (Scatters). At any time during the game, on any non-winning spin, the Queen’s Heart may throw out 4 to 7 Heart Wilds to be added to random symbol positions, creating more winning opportunities.

Agent Features

The Agent Features are unlocked by collecting six of each associated character symbol. Each Agent Feature has a unique power-up which destroys and transforms other symbols on the grid. It is possible that on any spin, the White Rabbit may appear and instantly unlock an Agent Feature.

  • Cupcake Splat: the Dormouse patters across the grid leaving a trail of cupcake ‘bombs’ in its path which then explode to remove or transform the symbols underneath
  • Smokin Phat: the Caterpillar blows diagonal smoke trails across the grid which will then remove or transform the symbols underneath
  • Grinning Cat: the Cheshire Cat will grin on the grid which will enlarge before disappearing and remove or transform the symbols underneath
  • Mad Hat: the Mad Hatter throws between 6 to 9 hats onto the grid at random symbols, the hats spin and disappear before then removing or transforming the symbols around and underneath

Queen’s Heart Free Spins

Land three Scatter Keys to unlock the Queen’s Heart. This will trigger one free spin where all four Agent Features are activated. Once the Agent Features have played out, the Queen’s Heart releases 4 to 7 Random Heart Wilds plus a Mega Wild onto the grid, creating further winning combinations for the grand finale.

Agent of Hearts Overall Verdict

The theme and graphics for Agent of Hearts are fun and entertaining. This is a simplistic game to play and would suit any novice. The bonus features Cupcake Splat, Smokin Phat, Grinning Cat and Mad Hat are interactive and appear regularly on the reels, enticing you to keep on spinning.

Some Tricky Features

Unfortunately, we found that the landing of three Scatter Keys was far more illusive to appear on the reels and when they did, we were slightly disappointed at the ‘grand finale’. The additional features for the grand finale consist of one free spin and a mega wild (2x3) with no option to re-trigger.

The bonus for the finale was seeing the Agent Features all play out and some Random Heart Wilds thrown in for good measure. With all that said, the Agent Features can be most lucrative and your win pot never seems to be empty. Cluster wins are certainly helpful on a grid of this size.
