# Tower Defense vs Continuous TD

The clearest difference is rating: Tower Defense at 3.6 against Continuous TD's 3.0. Tower Defense also leads on ads (none vs shown) and ratings volume (23 vs 1). Continuous TD's advantage is in-app purchases (none vs 10). On price, monetization model and device support there is nothing between them.

Both are free to download. Tower Defense sells 10 one-off in-app purchases. Continuous TD asks for nothing beyond the download.

Tower Defense holds the better App Store score, 3.6 against 3.0. That said, the two scores are not equally well evidenced: Tower Defense has 23 ratings behind it against 1, so its average is the more settled of the two.
