HEARTSHOT HOLDINGS Games, made with heart.
The Red Prince, captain of Cross My Heart, at the rail of his ship at dawn

🏴‍☠️ Cross My Heart · The Flagship Game

Call the shot.
Keep the oath.

A pirate duelling game across the Lantern Coast, where the boldest mechanic in the game is your own voice: call your shot out loud, and the current answers.

⚔️ The Duel

How a duel runs

1

Build, and choose your Captain

Assemble a deck of forty to sixty cards from your collection and seat a Captain to lead it. Every Captain bends the game their own way — pick the one whose promise you can keep.

2

Set your crew, call your shot

Play your crew to the field, then strike. Before the blow lands you may call the shot: name your mark, out loud, and mean it. The current is listening.

3

The sea decides

A true call lands. A hollow one misses. Duels turn on nerve as much as numbers — face the rival captains the game deals you, or challenge a friend head to head online.

⚓ The Captains

Every deck sails under someone

Your Captain isn't a figurehead. They set the terms of the duel — their court, their colours, their way of winning. The Red Prince leads the flagship court, but the Lantern Coast is crowded with rivals: storm-calling tengu, drowned courts, knotling swarms, iron works and fae courts, each with a strategy of their own.

512 cards make the pool — captains, champions, tactics, gear, and the domains they fight over — all built on rules that work the same printed on a table as they do on a screen.

🕯️ The Annals

A whole coast of lore, inside the game

The duels are only the weather. The Annals — the game's own book of persons, places, and deeds — carry the whole story of the Lantern Coast, and it grows with every set.
