Major update

Mima Returns! - Oct,29 2025

TOUHOU GENSOU MAHJONG · published 28 Oct 2025, 16:19 UTC

All eventsPlayers around this dateRead on Steam

We have updated Touhou Fantasy Mahjong to v1.2.16.

To coincide with the release of the Switch package version (in Japan), the Steam version will also be updated.

Feature Additions

Chinese (Simplified & Traditional) Support

“ Cirno's Mahjong class” has also been translated. Enjoy!

Mima Returns!

To commemorate the Switch package release, Mima—who appeared in the doujin version of the Touhou Gensou Mahjong series—has made a comeback! She is now available for all players on every platform. Her abilities have been slightly enhanced from her original version. Enjoy her wonderful illustration by Katakei!

Auto-Screenshot for Winning Hands

Added a feature to automatically take a screenshot when winning with a certain number of han or higher. You can set the required han count in “Advanced Settings”.

※Auto-screenshots only work when a player wins.

Discard Tile Assistance

Exclusively for Vs. CPU modes, a feature has been added to mark tiles that “bring you closer to winning” and tiles that “move you further from winning” when discarded. This can be toggled ON/OFF in “Advanced Settings,” but it is always ON within “ Cirno's Mahjong Classr”, It is always OFF during network battles.

System Voice Additions & Refinements

New system voices have been recorded. Voice acting continues to be provided by Yuki Dōsaka.

Voices for some previously inconsistent menu items have been re-recorded, and new system voices have been added to certain scenes. Overall, the atmosphere should feel brighter.

Rebalancing

Adventure Mode

Difficulty has been lowered for some challenges. The conditions in parentheses below are the criteria for clearing the challenge up to v1.2.15a.

  • Dream World 3 (Three Concealed Pungs) → Prohibits abilities for all players except yourself

  • Dream World 4 (Hitori-uki condition) → Changed to require a 10pt+ lead over Junko

  • Saishi No Michi Walk 3 (You top, Komachi last) → Changed to require a 20pt+ lead over Komachi

  • Shinreibyou 3 (Hitori-uki condition) → Same condition, but starts in the South round 1 with a Hitori-uki condition, already holding 35,000 points.

  • Chireiden 3 (You top, Shion last) → Changed to a 30pt+ lead over Shion (unconditional clear if you are top)

  • Yokai Mountain 4 (Hitori-uki condition) → Two or more players other than yourself must be sunk (OK if CPU is the floating player)

  • Bamboo Forest 4 (Under Deflation Rules + No Penalty for No-Ten + No Renchan Bonus conditions, +35.0p or more) → +20.0p or more

  • Sunny Fields 1 (Win with 60 points or more) → Enabled Ability

Bug Fixes

  • Fixed an issue where deposits collected after a match ended sometimes didn't reflect in the total points

  • Fixed a memory leak that occurred when “ Retry ” a match in Adventure Mode, etc.

We sincerely appreciate your continued support for Touhou Gensou Mahjong.
