# Prison Tower vs Buildy Blocks

The clearest difference is review sentiment: Prison Tower at 72% against Buildy Blocks's 32%. Prison Tower also leads on in-app purchases (none vs 5). Buildy Blocks's advantage is ads (none vs shown) and update cadence (every 2 days vs every 4 months). On price, ratings volume and device support there is nothing between them.

Buildy Blocks holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 14 and 30 respectively. Written reviews complicate that: 72% of Prison Tower's written reviews are positive against 32% of Buildy Blocks's, so the app with the better star average is not the one people write more warmly about.
