Overview

About this game

A Deckbuilding Battle Game Featuring Touhou Characters!

Build your ultimate deck using 150+ cards and 25+ characters,
and race to buy out the Hakurei Shrine before your opponents!

What is a Deck-Building Game?

At the start of the game, players have no cards.
During play, you’ll acquire new cards and strengthen your deck as the match progresses.
Carefully watching what cards your opponent collects and building your own deck strategically is key to victory!

Sounds Complicated…?

GensouKoroKoro is designed to be easy to pick up, even for players new to deckbuilding games.

While there are card synergies to discover,
almost any card you buy will help bring you closer to victory.

Game Features

  • Most cards activate based on the result of a dice roll,
    but many cards can also activate independently of dice results,
    allowing for a wide variety of deck strategies.

  • Players select six characters before the match and use two of them during gameplay,
    so you can always play with your favorite characters.
    (Characters are not shared or contested with other players.)

  • A large variety of cards and supply sets ensures that every match feels different.

  • The Weather System introduces special effects that activate each turn.
    Weather conditions are randomly chosen every match,
    encouraging flexible and adaptive deckbuilding strategies.

  • In addition to Quick Match against random opponents,
    you can also play Lobby Matches with friends.

  • Each character features their own unique background music,
    with 30+ tracks planned for the full release.
