Agent of Hearts Online Slot Review

Head down the rabbit hole to the Alice in Wonderland-themed Agent of Hearts slot. It’s one of a series of Play'n GO slots inspired by the famous stories from Lewis Caroll, and joins Rabbit Hole Riches and Court of Hearts at the best desktop and mobile casinos.

Agent of Hearts plays out across 7 reels, with an unusual 7-7-5-5-5-7-7 pattern of symbols. Beautifully detailed images of the Mad Hatter, Mouse, Cheshire Cat, and other characters pack the reels, and you need to create clusters of matched symbols to win.

Random wilds help to complete wins, and there are plenty of extra features. These include cascading symbols and a collection feature that leads to symbol transformations, removals, and a valuable free spins round.

Prizes from this medium to high volatility game can reach 5,262x your bet, or 526,200.00 at the maximum bet. Average returns come in at 96.25%.

How to Play the Agent of Hearts Slots Game

The various Alice in Wonderland characters will be familiar to almost anyone, although Alice herself isn’t among them. A selection of colourful jewels also appear, along with a glowing wild symbol that stands in for others if needed.

Character collection meters sit to the left side, (or above in the mobile version), and the reels are set in a suitably strange world, with teapots and cups floating in the sky above the trees of the palace gardens. It looks fantastic on iOS, Android, and Windows mobiles, and on desktop platforms at the best online casinos.

The controls are very easy to use, and you pick a bet level from a scroll bar, with options running from as little as 0.20 and as much as 100.00 on each spin. A small circular arrows button starts the reels spinning automatically, and the blue ‘I’ tab unlocks the paytable. This table lists how much each symbol is worth when you match clusters of 5 or more, with the Mad Hatter paying out a crazy prize of up to 1,000x your bet.

Free Spins & Other Agent of Hearts Bonus Features

A cascading reels mechanism removes winning symbols and allows those above to drop down. Cascades run for as long as they create clusters, with no upper limit. A randomly awarded Heart Wild feature adds between 4 and 7 wilds to the grid on losing spins to hopefully form new wins.

The various characters collect in their respective meters to the side of the symbol grid. If a character fills its meter during a spin or series of cascades, they unlock their own special feature.

The dormouse leaves cupcake bombs across the reels, which explode to remove symbols for a cascade. In the Smokin’ Phat feature, the caterpillar blows smoke across the game, removing symbols. The Cheshire Cat removes or transforms symbols below him, and the Mad Hatter does the same to between 6 and 9 symbol positions. Each of these ‘Agent’ features make it easier to see new winning clusters, although it’s not guaranteed.

Collect 3 keys during a sequence of cascades to unlock the Queen’s Heart free spins feature. It’s a single spin, but all 4 character features play out one at a time to trigger cascades. Once these come to an end, a 3x3 Mega Wild symbol appears for a guaranteed win. 

Thereby, some of our recommended online casinos are offering a free spins no deposit bonus.
