About
The emperor has died suddenly, leaving seven princesses vying for the throne! The fate of the empire hangs in the balance – who will rise to lead and prevent it from falling into chaos?
HEART of CROWN Online is a card game where you build a deck, inspired by the board game HEART of CROWN 2nd Edition, which was updated and re-released in 2022.
System
- A four-player turn-based game.
- Use the money you earn from your estates to buy new lands and various action cards to advance your game.
- Once you have enough resources, you’re ready to recruit the Princess! Every Princess has a powerful effect, but be careful, the early bird gets the worm.
- Get the senators, dukes, and other influential people on your side, and when your “succession score” reaches 20 points, you will be crowned. The throne is yours.
- Online cross-play is supported! Ranked matches and free matches are also available.
Story
Long ago, in a world of swords and magic, an empire brought peace to the land after years of war. But just as the peace was settling in, the emperor became sick, and there was no one to take his place…
If this continues, we could be back to a war-torn world!
You hold a position of great power within the empire. Your urgent task is to secure the new emperor’s rule and maintain peace and unity across the land. While the previous emperor didn’t have any sons, he did designate seven potential successors, including two princesses who are direct heirs.
Now, let’s get the princess of your dreams to ascend to the throne!
