# Crystal Caverns! vs Tower Buster

The clearest difference is review sentiment: Crystal Caverns! at 86% against Tower Buster's 47%. Crystal Caverns! also leads on in-app purchases (none vs 1) and iOS requirement (11.0 vs 15.0). Tower Buster's advantage is rating (4.7 vs 4.2) and update cadence (every 2 months vs every 36 months). On price, ads and device support there is nothing between them.

Both are free to download. Tower Buster sells 1 one-off in-app purchase. Crystal Caverns! asks for nothing beyond the download.

Tower Buster holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Tower Buster has 16K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 86% of Crystal Caverns!'s written reviews are positive against 47% of Tower Buster's, so the app with the better star average is not the one people write more warmly about.

Crystal Caverns! ships an update every 36 months, Tower Buster every 2 months. The most recent releases landed on October 14, 2026 and October 18, 2026 respectively.
