ReceptionRating · Positive reviews · Number of ratings

Ball Master holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Ball Master has 2.3K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 83% of Blox 3D Junior's written reviews are positive against 63% of Ball Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Blox 3D Junior ships an update every 9 months, Ball Master every 3 months. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
