■ It’s this kind of game
This is a single-player card game where you compete against queens from around the world using their country's traditional card game.



■ A challenge to enjoy for a long time


■ A game that keeps growing
Queen Breaker is not yet finished; it is a game that continues to grow.
■ Introduction to the Queen
♠ Koharu — Japan · Queen of the Ward · Gene Rummy
A nurse working only night shifts. She takes out a card instead of seeing a patient.

The lord of the Bavarian castle. Saying he can't concentrate on the cards, he decides on the penalty first.

Principal Flamenco dancer at the Grand Theatre of Madrid. Even off stage, he doesn't know how to lose.
♣ Dakota — American West · Queen of Saloon · Three Card Poker
Owner of the oldest saloon in Tombstone. Never lost in the master bedroom.

A Nord Elf warrior guarding Bergen Harbor. He boasts that he has never lost a battle.
♥ Han Seo-a — South Korea · Queen of Social Media · Gambling Family Heirloom
Exclusive model for a Hanbok brand and influencer. The loser gets photographed — but they set the angle themselves.
♦ Thalia — Greece · Queen of the Aegean · Xeri
A painter from Milos Island. He is the first to offer to be a model for the print.
♣ Cordelia — England · Queen of Archives · Crevice
Archives of the Royal Archives at Windsor Castle. He upheld the dignity of a scholar on the cleavage plate.

The Pharaoh's youngest princess. She decides everything by edict and insists she doesn't know how to lose.
♥ Bella — Brazil · Queen of Carnival · Truco Paulista
The Queen of Bateria at the Rio Samba School. To her, Truco is another samba.
♦ Ileana — Romania · The Witch of Bran Castle · Macau
A novice witch at the magic apothecary below Bran Castle. Her spells are grandiose, but the results always go astray.
♣ Luna — Librarian
The only person in this world who remembers 'play'. He teaches the rules and points out moves via notes during the game.




■ Story — A World Where Play Was Not Born
Three o'clock in the morning, at my regular board game cafe. The moment I flip over a card I’ve never seen before, light pours out from a cracked crown.
The place where I opened my eyes was a parallel world with the exact same map as ours. There is only one thing: 'play' was never born in this world.
A world without cards or board games. Queens who have everything find no joy in anything, and the world is gray.
Please teach the queens how to play the game.
Join Luna in teaching the queens their country's card game and battle them. If you defeat a queen, the color returns to that country.
■ It's okay if it's your first time

■ How to Use
You can enjoy the game using only a mouse. Click a card to select, and use the buttons to proceed.
■ Producer's Comment
Card games in this genre usually end with just Texas Hold'em. However, there are far more two-player card games around the world that have been refined by people in various countries over hundreds of years, and each offers a different kind of fun to learn. I started making this because I wanted to properly capture those games.
We did not make this easy. We ran the AI against each Queen hundreds of times to measure win rates and adjusted the difficulty to ensure that victory is possible once you learn. You might lose the first couple of games. However, once you master the rules and start reading the Queen's expressions, the moment of victory will surely come.
The illustrations, videos, and audio were created with the help of generative AI, while the rules, AI, and direction were crafted by hand. Currently, there are eleven queens and eleven games, but we will not stop here; we will continue to expand with new queens and games through updates and DLC. We would be delighted if you enjoyed learning.
