# Spin Spin Defense vs Castle Cracker

The clearest difference is rating: Castle Cracker at 3.8 against Spin Spin Defense's 2.3. Spin Spin Defense's advantage is update cadence (every 5 days vs every 2 months) and review sentiment (50% vs 40%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Spin Spin Defense sells 36 one-off in-app purchases and Castle Cracker sells 16 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Castle Cracker holds the better App Store score, 3.8 against 2.3. Both are backed by a comparable volume of ratings — 3 and 5 respectively. Written reviews complicate that: 50% of Spin Spin Defense's written reviews are positive against 40% of Castle Cracker's, so the app with the better star average is not the one people write more warmly about.

Spin Spin Defense ships an update every 5 days, Castle Cracker every 2 months. Both last shipped on October 24, 2026.
