Version 0.23 Oicho-Kabu Update

Battle Hanafuda · published 8 Jun 2026, 23:55 UTC · build 23631636

All newsPlayers around this dateRead on Steam

In this mini update, we've made several improvements to Oicho-Kabu (Public Beta).

  1. Added the new winning hands "Hanami-Sake" and "Tsukimi-Sake"

  2. Added a replay confirmation after the game ends

  3. Fixed minor issues

Added "Hanami-Sake" and "Tsukimi-Sake"

We have added the new hands "Hanami-Sake" and "Tsukimi-Sake", which are formed by combining the September Seed card (Sake Cup) with either the March Bright card (Cherry Blossom) or the August Bright card (Moon).

These hands have been balanced to be stronger than Arashi, but weaker than Akatan.

Since they can be completed with only two cards, their reward multiplier is set to 4x, slightly lower than the 5x multiplier used for other Koi-Koi hands.

Added a Replay Confirmation

In previous versions, the game would immediately return to the title screen after a match ended, making it somewhat inconvenient to start another game.

This has been improved by adding a replay confirmation screen, allowing players to jump into another match more easily.

Bug Fixes

Fixed an issue where mouse controls did not function correctly on certain screens.

However, it ended up sounding like an arrangement of Kotaro's Theme, so I decided to scrap it. Still, there is no limit on the number of tracks I can include, and the only real downside to adding one is an extra 45 KB of installation space—the size of the .vgm file…In-game event7 Sep 2026Version 0.37This update adds a CRT filter that recreates the look of a CRT display.
