Agent of Hearts Slot Review

Lewis Carroll’s surreal stories have been a great inspiration for a number of wacky video games and slots. We’ve taken endless trips to Wonderland so far in unusual slot games where nothing is as it looks. Play’n GO takes us on such a trip once again with its slot called Agent of Hearts.

A Wonderland-based slot with unusual mechanics and gameplay, Agent of Hearts is a Cluster Pays slot machine with plenty of magical surprises. It hides a secret deep under the Queen’s heart, locked away with 3 keys. Find them all to unlock the secret, and you can win over 5,000 times your wager.

The Agent of Hearts slot is a Cluster Pays game that can deliver massive base game wins with the right combination of symbols. Play it for free or real money in all the newest online casinos and take a trip down the lucrative rabbit hole. It’ll be worth it.

Agent of Hearts Slot Setup and Paytable

The Agent of Hearts slot is a 7x7 game based on Lewis Carroll’s stories. You probably know what to expect on the reels – rare gems, the Cheshire Cat, the Mad Hatter, and other popular characters from the heart of Wonderland. At the center of it all is the Queen’s Heart, which is kept under lock and key.

Play’n GO has nailed down the magical looks and atmosphere. Its surreal imagery is boosted by a great soundtrack and sound effects. According to the paytable, the Mad Hatter pays the most – 2.5x your wager for a cluster of 5. Just like in all Cluster Pays slots, the biggest payouts are for clusters of 15+. In Agent of Hearts, you can land a win over 1,000 your stake in this way.

Agent of Hearts Slot Base Game

Cluster Pays slots are fun from the start till the end, and Agent of Hearts is no exception. The action starts rolling as soon as you place your wagers. You can choose between €0.20 and €100 per spin with a range of denominations in between.

Hit the Spin button, and your Wonderland adventure begins. The main highlight of the Agent of Heart online slot is the Cluster Pays mechanic. The Cluster Wins feature is triggered on any win. All winning symbols are removed from the reels at that point, and new symbols drop from the top. The cascades will continue as long as new winning clusters are made.

A random Wild feature is triggered on non-winning spins. The slot will randomly add 4-7 Wilds on the reels, which can significantly boost your wins.

Look to the right side of the reels, and you’ll see a meter that can be filled with different symbols. Score a 4+ cluster win with one of the corresponding symbols, and it’ll be collected in the meter. If you fill all 6 positions, you’ll trigger a corresponding feature.

  • Grinning Cat: Cheshire Cat transforms or removes symbols beneath it.
  • Cupcake Splat: Dormouse runs from the top to the bottom of the reels, leaving a trail of cupcake bombs that remove symbols when they explode and transform symbols into new ones.
  • Mad Hat: 6-9 Mad Hatter symbols are added to the grid, creating new symbol drops or transforming symbols into matching ones.
  • Smokin’ Phat: The Caterpillar puffs a cloud of smoke and blows 1, 2, or 3 puffs diagonally on a grid. When it clears, some symbols are either removed or transformed.

At any point during the base game, the White Rabbit can award an Agent feature randomly. You can’t affect this in any way – it’s a completely random feature.

Agent of Hearts Slot Free Spins Round

Collect 3 keys on a single spin or set of cascades, and you trigger the Queen’s Heart free spins feature. You only get a single free game, but it plays out the 4 Agent features. Score Cluster wins in the Free Spins Round, and a 3x2 Mega Wild can be added to the reels, giving you a shot at higher rewards.
