Riichi Mahjong Calculator1.1.2

Enter a riichi mahjong hand to examine tile choices, possible development, winning patterns, and the resulting score from one Android utility. Riichi Mahjong Calculator brings hand efficiency, meld hand efficiency, winning-hand analysis, and score calculation together instead of requiring separate calculations.

Its hand-efficiency functions assess tile efficiency and backwards strategy, while also checking good-shape tile efficiency for one-shanten hands. The meld analysis covers tile efficiency for chow, pung, kong, and pass decisions, with the same one-shanten good-shape assessment and backwards-strategy support. These tools concentrate on the listed hand-development and decision analyses rather than extending into unrelated features.

Winning-hand analysis uses Mahjong Soul and Tenhou rules as its defaults, with some options for adjusting those rules. Score calculation works from fan and minipoints and follows those same defaults with limited customization. It suits players studying riichi mahjong and anyone reviewing choices or results during play on a mobile device.

The open-source application is intended for Android devices running Android 7.0 or later. Riichi Mahjong Calculator 1.1.2 supports arm64-v8a, armeabi-v7a, x86_64, and x86 architectures.
