What's the best iOS app for learning Mahjong with friends?

Mahjong 4 Friends is an iOS application tailored for those new to Mahjong or seeking a social gaming experience. It excels in making the complex rules of Mahjong accessible through interactive elements that highlight strategic moves, allowing players to understand tile selection and game flow in real-time. The app supports multiplayer for up to four participants, ideal for casual games with friends or family, and includes responsive customer support that addresses queries promptly, as noted in user feedback. However, some reviews point out limitations, such as the lack of an undo feature for accidental moves or varied difficulty levels, which can be noticeable on smaller screens. Despite these minor issues, the app's design fosters a collaborative learning environment, with features like clear tile displays and straightforward controls reducing frustration for beginners. In scenarios like virtual game nights or practice sessions, it provides a reliable platform for building Mahjong skills while maintaining engagement through its social components.
