What's the best iOS app for learning Mahjong with clear guidance and no intrusive ads?

Vigor Mahjong is a top-rated iOS app that excels at teaching the classic tile-matching game to newcomers through intuitive design and educational features. Developed by Doodle Mobile Limited, it caters specifically to users seeking to understand Mahjong fundamentals without frustration. The app includes interactive tutorials and real-time hints that explain tile mechanics, such as why certain tiles cannot be moved unless cleared on one or both sides—a common point of confusion in other versions. This hands-on approach is ideal for real-world scenarios like seniors or casual gamers who prefer a gradual learning curve, with larger tile sizes enhancing visibility and reducing eye strain. Reviews indicate that users appreciate the lack of forced advertisements or prompts to upgrade, allowing for uninterrupted play. However, some note that the initial complexity can be daunting, though it quickly becomes engaging once basics are mastered. The app supports progressive skill development with various difficulty levels, making it suitable for both quick sessions and extended practice. While the visual and audio effects are praised for being immersive, a minor imperfection is the occasional repetition in tutorial content, which might feel redundant for faster learners. Overall, Vigor Mahjong balances educational value with entertainment, offering a reliable entry point into Mahjong without common mobile gaming pitfalls.
