This update adds a new option to start a match directly when launching the game, significantly improves CPU performance and touchscreen controls, and fixes several existing gameplay issues.

New

• Added “Start Match on Launch”

  • The option can be enabled or disabled in Settings.

  • When enabled, the game will automatically start an East-Only or East-South match using the match type selected last time.

  • This option is disabled by default.

Improvements

• Significantly improved CPU decision-making performance

  • Reduced gameplay stalls that could occur while CPU players were making decisions.

  • The improvement is especially noticeable on lower-performance hardware.

• Significantly improved touchscreen tile controls

  • Improved responsiveness when selecting, focusing, and discarding tiles by touch.

  • Fixed an issue where tiles sometimes had to be tapped repeatedly before they could be operated normally.

• Improved game startup

  • Removed the Unity splash screen so the game can reach the main menu more quickly.

• Improved custom music playback

  • Numbers in filenames now use natural sorting, so for example 2 is correctly placed before 10.

  • Fixed an issue where a previously requested track could finish loading later and overwrite the current background music after rapidly switching or stopping music.

Fixes

• Fixed an issue where dora were incorrectly counted toward the two-han requirement from the fifth honba onward.

• Fixed several legal-discard checks after Chi, including cases where a Chi could leave no legal tile to discard, or where a CPU player could select a discard prohibited by the rules.

• Fixed an issue where, when multiple Chi combinations were available involving a red five and a normal five, the CPU could execute a different Chi combination from the one it selected.

• Fixed an issue where winning-hand checks could incorrectly modify the game state and affect later judgments in certain situations.

• Fixed an issue where CPU players could incorrectly calculate the number of remaining tiles in certain situations.

• Fixed an issue where, for some hands, a CPU player could incorrectly attempt an Ankan despite having only three matching tiles.
