How to Play

It is easy to get started playing the Agent of Hearts slot game. You can do so by setting your bet using the heart arrow + and – signs under the reels. Once your bet has been set, hit the green spin button to send the reels tumbling. Bets per spin range from 20p to £100.

This is a cluster pays style slot game and so the aim is to get winning combos of five or more matching symbols, also known as clusters.

The symbols on the reels of this game are:

  • Yellow pentagon gem
  • Green circle gem
  • Purple diamond gem
  • Blue triangle gem
  • Dormouse
  • Caterpillar
  • Cheshire cat
  • Mad hatter


In the base game, the mad hatter is the highest value symbol on the reels and will award up to 1000x your stake for a cluster of 15 or more. The maximum win available is 5,262.5x your total stake.

Special Features

In the Agent of Hearts slot game, there are a massive seven special features to enjoy including cluster wins, random heart wilds, the agent feature and the queen of hearts free spins.

Agent of Hearts uses the popular cluster pays mechanism to award wins. Each time you get a winning cluster, the symbols in that cluster are removed from the reels to make way for new symbols to fall in their place. This can potentially create more winning combos and this process continues. It will only end when no new winning cluster is formed.

The hearts wild feature triggers at random after non-winning spins. Four to seven wild symbols will be randomly added to the reels which can help contribute towards new winning combinations.

Players will spot four metres on their screen and each corresponds to a different character symbol which are the dormouse, caterpillar, Cheshire cat and mad hatter. Each time you get a winning combo, the symbols in that combo will be collected by the associated meter. If the six positions on the meter are filled in one spin, it will trigger its designated feature. There are four features that can be triggered:

  • Dormouse cupcake splat feature – watch out for the dormouse running across your reels and leaving cupcake bombs that explode to allow new symbols to fall into their place and potentially create new winning combos
  • Caterpillar smoking phat feature – the caterpillar makes an appearance to blow between one and three trails of smoke diagonally across the reels. Symbols in the way of the trail can either be removed or will have transformed into a new symbol
  • Cheshire cat grinning cat feature – the Cheshire cat will remove or transform symbols on the reels
  • Mad hatter mad hat feature – six to nine mad hatter hat symbols are added to the reels and these will start spinning to remove adjacent symbols. This will cause symbols to drop down and potentially create new winning combos.

Players should also watch out for the famous white rabbit as this can appear at random to trigger the agent feature. When this happens, the four feature modes above will play out in this order and the symbol meter will reset with every new spin.

Lastly, we have the Queen of Hearts free spins feature which is triggered by collecting three keys in one spin or cascade set. Players are awarded one free spin and the agent feature with the four different modes will play out. What’s more, 3×2 mega wild symbol will be added to your reels to provide more opportunities to trigger wins.

Graphics and Sounds

Visually, Agent of Hearts looks incredible and players will not be disappointed spinning the reels of this Play N GO slot. The theme of this game is the iconic Alice in Wonderland tale and the storyline of this specific slot is that the Queen of Hearts has her heart locked away in order to protect Wonderland’s wealth. As someone has stolen the key, it is your job to get it back. Behind the reels you will spot the outline of Wonderland with trees and floating teapots. While the background is very dark, the symbols on the reels are very bright and colourful. The low value symbols are the range of coloured gemstones while the high value symbols are the various popular characters from the story including the dormouse, caterpillar, Cheshire cat and the mad hatter. A mystical, fantasy inspired soundtrack plays in the background as you spin the reels which fits perfectly with the Wonderland theme.


Agent of Hearts is the third slot game in Play N GO’s Rabbit Hole Riches series and it does not disappoint! Players will enjoy the beautiful, high-quality graphics in this game as well as the huge range of bonus features that can help you take home some big wins of up to 5,262.5x your stake. The cluster pays mechanism can make this a very lucrative slot game to play and players will also love the free spins round and agent feature with the four different modes to play in. If you are looking for a slot with stunning graphics and unique gameplay, this could be the one for you!
