## Review summary

Users appreciate that the app stays true to the classic Einstein puzzle and offers a good brain exercise with a user-friendly interface. However, many find the excessive ads intrusive, mandatory for progression, and the lack of an offline mode frustrating. The app requires a constant internet connection with unclear justification, has limited puzzle variety and difficulty, and lacks autosave, which diminishes the user experience.
