About the Game

Heart Duels

Heart Duels is a tactical card battler where positioning matters as much as the cards you play. 

Duels take place on a compact tactical board with front rows, back rows, and special cover lanes.

Units have keywords and abilities. At your disposal are spells and items.

Heart Duels rewards those who master their cards, and the tactics of the board.

Your cards alone do not determine your fate. It is your skill and tactics that will determine if you win or lose.

Sharpen your wits and deploy stratagems to become the King of Duels.
