Mahjong School is a free Android app that teaches you how to play Japanese style Mahjong, which is similar to European style (Riichi) and US style Mahjong. While it may differ slightly from Chinese, Hong Kong, or Taiwan style, mastering the Japanese style makes it easy to switch to other styles. The app offers three ways to help you learn Mahjong: a Mahjong calculator, a simple tutorial, and a practice mode.
The Mahjong calculator allows you to add tiles to your hand and set various conditions such as DORA and self-draw to calculate the hand of FU and point, with detailed descriptions such as hand names. The simple tutorial lists all the HAN, including an example hand and a description. The practice mode lets you play Mahjong directly with entry-level AI, which is very friendly for Mahjong learners. Practicing is the best way to learn Mahjong.
Overall, Mahjong School is an excellent app for anyone interested in learning Japanese style Mahjong. The app is easy to use, and the three learning modes make it suitable for players of all skill levels. If you have any feedback or suggestions, please feel free to send an email to the developer.
