# Miner Gun Builder vs Sphere TD

The clearest difference is update cadence: Sphere TD at every 3 days against Miner Gun Builder's every 6 weeks. Miner Gun Builder's advantage is rating (4.9 vs 4.6) and ratings volume (178 vs 10). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Miner Gun Builder sells 19 one-off in-app purchases and Sphere TD sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Miner Gun Builder holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Miner Gun Builder has 178 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 94% of Miner Gun Builder's written reviews are positive against 100% of Sphere TD's, so the app with the better star average is not the one people write more warmly about.

Miner Gun Builder ships an update every 6 weeks, Sphere TD every 3 days. The most recent releases landed on October 25, 2026 and October 28, 2026 respectively.
