Game overview
What is Agent Of Hearts?
Your mission, should you choose to accept it is the retrieve the keys to the Queen’s Heart. Here’s how... Symbols drop into the grid; the aim is to get the biggest cluster of symbols possible (five or more). Only the highest win in the cluster is paid, then the winning symbols are removed, followed by new symbols that cascade to fill the gaps. Multiple clusters of the same symbol that are not connected are paid as separate clusters. On any non-winning spin, there is a chance for four to seven Random Heart Wilds to be added to the grid. Heart Wilds can substitute all symbols except Keys. Agent symbols are collected when they form part of a winning combination; collect six to unlock the associated Agent feature. Alternatively, the White Rabbit may randomly appear and instantly unlocks an Agent feature. Agent features trigger after winning combinations and cascades finish. If multiple Agent features are unlocked simultaneously, then the sequence in which they play are as follows: Cupcake Splat, Smokin’ Phat, Grinning Cat, Mad Hat. Agent features cannot be re-triggered and are guaranteed in the Queen’s Heart Free Spin. Agent features reset at the start of each spin. AGENT FEATURES Cupcake Splat The Dormouse runs across the grid from top to bottom, leaving a trail of cupcake bombs behind him. The cupcake bombs explode and either remove the symbol beneath or transform it into a randomly selected symbol. Smokin’ Phat The Caterpillar blows one to three trails of smoke across the grid in diagonal lines. The smoke will either remove the symbols beneath or transform them into a randomly selected symbol. Grinning Cat The Cheshire Cat’s grin appears over the grid, removing the symbols beneath or transforming them to a randomly selected symbol. The Mad Hatter Six to nine of The Mad Hatter’s hat will appear over the grid. The hats spin and remove any adjacent symbols before transforming the symbol underneath into a randomly selected symbol. Collect three Keys in one spin to trigger the Queen’s Heart Free Spin. The Queen’s Heart Free Spin is a single free spin that cannot be re-triggered as Keys are removed from the grid, and no more Keys can land during this feature. In the Queen’s Heart Free Spin, each Agent feature is unlocked and plays out in sequence: Cupcake Splat, Smokin’ Phat, Grinning Cat, Mad Hat. When the cascades have concluded, the Queen’s Heart Mega Wild unleashes the Random Heart Wilds feature before jumping onto the grid itself, as a 3x2 Mega Wild symbol, that substitutes all symbols. Curiouser and curiouser!
