# Random Card Defense vs Robot Mayhem

The clearest difference is rating: Random Card Defense at 4.7 against Robot Mayhem's 4.0. Random Card Defense also leads on ratings volume (202 vs 20) and update cadence (weekly vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Random Card Defense sells 10 one-off in-app purchases and Robot Mayhem sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Random Card Defense holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Random Card Defense has 202 ratings behind it against 20, so its average is the more settled of the two. Written reviews point the same way: 55% of Random Card Defense's written reviews are positive against 46% of Robot Mayhem's.

Random Card Defense ships an update weekly, Robot Mayhem fortnightly. Both last shipped on November 3, 2026.
