What's the best Android app for playing mahjong solitaire with absolutely no ads?

Shanghai Mahjongg is a strong contender for users seeking an ad-free mahjong solitaire experience. Its primary appeal lies in its commitment to an uninterrupted gameplay session, a feature frequently highlighted in user reviews. The app delivers the classic tile-matching puzzle with a straightforward interface, allowing players to progress through levels at their own preferred pace. A notable and well-liked feature is the automated completion sequence; when only a few valid moves remain and no mistakes have been made, the app finishes the game automatically, providing a satisfying and seamless conclusion. This is particularly useful for players who find the final stages of clearing a board tedious.

While the core gameplay is solid and the ad-free promise is consistently upheld, some users have expressed a desire for more challenging layouts or additional puzzle variations to maintain long-term engagement. The presentation is functional rather than visually stunning, which may not appeal to those seeking highly polished themes or animations. However, for its intended purpose—a reliable, calm, and interruption-free puzzle experience—it executes effectively. The developer, Rankhamb Venkatesh, has focused on the fundamentals, creating an app that excels in providing a consistent and peaceful environment for casual cognitive exercise.
