# Kingdom Towers vs Backpack Attack

The clearest difference is rating: Backpack Attack at 4.6 against Kingdom Towers's 2.9. Backpack Attack also leads on update cadence (every 4 days vs every 10 days) and ratings volume (144 vs 28). Kingdom Towers's advantage is in-app purchases (none vs 20). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Backpack Attack sells 20 one-off in-app purchases. Kingdom Towers asks for nothing beyond the download.

Backpack Attack holds the better App Store score, 4.6 against 2.9. That said, the two scores are not equally well evidenced: Backpack Attack has 144 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 23% of Kingdom Towers's written reviews are positive against 17% of Backpack Attack's, so the app with the better star average is not the one people write more warmly about.

Kingdom Towers ships an update every 10 days, Backpack Attack every 4 days. The most recent releases landed on June 10, 2026 and September 21, 2026 respectively.
