# Terradome 3D vs Mech TD

Terradome 3D and Mech TD both sit at 4.6 stars, but that hides the real split: 73% of Mech TD's written reviews are positive against 27% of Terradome 3D's. Terradome 3D's advantage is ratings volume (3.6K vs 124). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Terradome 3D sells 10 one-off in-app purchases and Mech TD sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Terradome 3D against 4.6 for Mech TD. That said, the two scores are not equally well evidenced: Terradome 3D has 3.6K ratings behind it against 124, so its average is the more settled of the two. Written reviews are what separate them: 27% of Terradome 3D's written reviews are positive against 73% of Mech TD's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
