Little will have Lewis Carroll known that one day his fictional stories would be used in video slots. There are countless titles swirling through on- and offline casino lobbies, although rarely with the original name as that has been trademarked. On this occasion, we get to see various characters such as the Mad Hatter and the Cheshire Cat as well as the giant heart that will be at the core of scoring big wins. All with Salazen Grum and other floating islands as the fitting background.

The pay symbols start at the low end with four gems in different shapes and colours – blue, purple, green and yellow – awarding 5x to 20x your bet for clusters of 15 or more symbols. They are followed by the Mad Hatter, the Caterpillar, the Dormouse and the Cheshire Cat. Hit 15+ clusters to win 40x to 1,000x your stake. An intricate icon with a red heart and marked with ‘W’ is the wild, substituting for all regular symbols. Lastly, a golden key on a red cushion acts as the scatter.

Rabbit Hole Riches: Agent of Hearts Slot Features

Agent of Hearts is the third in the Rabbit Hole Riches series from Play’n GO that started with the namesake slot in October 2020 and was further expanded with Court of Hearts in April 2021. On this occasion, they opted for their signature grid slot formula although in an unusual 7-7-5-5-5-7-7 format. Reason enough to take a closer look at how that works out.

The creative folks at Play’n GO are masters in developing grid slots, continuously honing their skills ever since they debuted the format more than a decade ago. As such, it is no surprise to see two mechanics – cascading symbols and cluster pays – being at the core of the gameplay on Agent of Hearts. At the start of a spin sequence, 43 symbols cascade onto the grid and landing five or more horizontally and/or vertically connected constitutes a winning cluster. Once payouts are evaluated, all winning symbols are removed and new ones drop in from the top. The process continues until no more wins occur.

Prepare for reel mayhem on Agent of Hearts courtesy of a plethora of modifiers and features that can be triggered at various stages during a game round. To start it all off are Random Heart Wilds. On any losing spin, there is a chance that 4 – 7 wilds will be placed on random grid positions, providing extra potential to hit a winning cluster.

The four Wonderland characters roaming on the grid will be the key to activating a number of Agent features. All agent symbols – Mad Hatter, Cheshire Cat, Caterpillar and Dormouse – landing in a winning cluster will be collected in their own meters to the left of the grid (desktop). Six are needed to unlock the respective Agent feature which will be queued until no more winning clusters occur. Each can be activated once per game round only while having more than one in the queue will see the modifiers play out in a fixed sequence as below:

• Dormouse – Cupcake Splat Feature: the Dormouse will run across the grid from the top to the bottom, leaving a trail of cupcake bombs in its wake. The cupcake bombs will explode and either remove the overlayed symbol or transform them into a random common pay symbol.
• Caterpillar – Smokin’ Phat Feature: the Caterpillar blows 1 to 3 trails of smoke across the grid in diagonal lines. The smoke will either remove the overlayed symbols or transform them into a random common pay symbol.
• Cheshire Cat – Grinning Cat Feature: the Cat’s grin appears on the grid, hovering over a number of symbols that will be either removed or transformed into a random common pay symbol.
• Mat Hatter – Mad Hat Feature: 6 to 9 of Mad Hatter hats will be placed in random positions. They will spin to remove any adjacent symbols while transforming the overlayed symbols into a random common pay symbol.

Any key scatters appearing within a game round will be inserted into the keyholes on the heart at the top of reels three to five. Collect three in one spin to trigger a single Queen’s Heart Free Spin, which cannot be retriggered but can pack quite a punch. All four Agent features – Cupcake Splat, Smokin’ Phat, Grinning Cat, Mad Hat – will be consecutively activated. Once all have been applied and no more wins occur, then the Queen’s Heart Mega Wild will first trigger the Random Wild Hearts feature before jumping itself to a random position on the grid in a 3×2 size.

Final Verdict

Rabbit Hole Riches: Agent of Hearts looks and feels like an entertaining slot with plenty of random and collectable features to keep you on your toes throughout a session. However, it might have been a good idea to give each character a different modifier although they are executed in various ways to make it appear less identical. Overall, another playable game with decent win potential emanating from the high-speed production lines of the Swedish studio.
