Version 0.36: Custom KoiKoi Rules in Online Battles

Battle Hanafuda · published 28 days ago · build 24638456

All events Players around this date Read on Steam

This update lets the room host configure rules equivalent to Custom KoiKoi when creating a Private Room in Online Battle.

Other Match Types Keep Their Existing Rules

Online matches outside Private Rooms (Quick Match / Friends Match) will continue to use the following fixed rules:

Rounds = 4
Hand Cards = 8
Field Cards = 8
Hanami/Tsukimi = 5pts
KoiKoi Calls = Once
KoiKoi Scoring = Standard

Network Compatibility

This update changes the network protocol used for online play.

As a result, Battle Hanafuda Version 0.35 and earlier cannot play online with Version 0.36 and later.

If matchmaking does not complete successfully, please make sure both players have updated Battle Hanafuda to Version 0.36 or later.
