# Marble Merge Factory vs Supernova

The clearest difference is in-app purchases: Marble Merge Factory at none against Supernova's 10. Marble Merge Factory also leads on review sentiment (100% vs 78%) and iOS requirement (15.0 vs 17.0). Supernova's advantage is ads (none vs shown) and rating (4.5 vs 4.0). On price there is nothing between them.

Both are free to download. Supernova sells 10 one-off in-app purchases. Marble Merge Factory asks for nothing beyond the download.

Supernova holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Supernova has 77 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Marble Merge Factory's written reviews are positive against 78% of Supernova's, so the app with the better star average is not the one people write more warmly about.

Marble Merge Factory ships an update every 2 weeks, Supernova every 2 days. The most recent releases landed on October 25, 2026 and October 28, 2026 respectively.
