What's the best Android app for playing a quick, daily board game with simple rules?

Backgammon by Easybrain provides a faithful digital version of the classic board game, specifically suited for users seeking a daily mental diversion. The app's core appeal lies in its simplicity and reliable structure, making it ideal for short, regular sessions like during a morning coffee break. A key feature is the Daily Challenge, which provides a new, curated game board each day, encouraging consistent but brief engagement. The interface is clean with traditional graphics, and games can be played offline against AI of varying difficulty. This makes it accessible for players of all skill levels, including older users who appreciate its uncomplicated nature. While the app is free, it is supported by advertisements that appear between games. User feedback indicates these ads are generally unobtrusive and can be closed quickly, though their presence is noted. The app does not focus on complex online multiplayer or social features, which keeps the experience focused and lightweight. Some long-term players mention that the AI can become predictable after extensive play, but for a reliable, daily puzzle-like board game experience, it fulfills its role effectively.
