# Blockz! Block Physics Simulate vs Merge Universe

The clearest difference is rating: Merge Universe at 4.9 against Blockz! Block Physics Simulate's 4.3. Merge Universe also leads on update cadence (every 5 weeks vs every 4 months) and ratings volume (110 vs 6). Blockz! Block Physics Simulate's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. Merge Universe sells 5 one-off in-app purchases. Blockz! Block Physics Simulate asks for nothing beyond the download.

Merge Universe holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: Merge Universe has 110 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 50% of Blockz! Block Physics Simulate's written reviews are positive against 47% of Merge Universe's, so the app with the better star average is not the one people write more warmly about.

Blockz! Block Physics Simulate ships an update every 4 months, Merge Universe every 5 weeks. Both last shipped on November 2, 2026.
