Verdict

The call

The clearest difference is rating: Blue Defense at 4.3 against Bimza Slots's 4.1. Bimza Slots's advantage is update cadence (every 5 weeks vs every 3 months) and review sentiment (94% vs 82%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Blue Defense sells 1 one-off in-app purchase and Bimza Slots sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Blue Defense holds the better App Store score, 4.3 against 4.1. Both are backed by a comparable volume of ratings — 20 and 10 respectively. Written reviews complicate that: 82% of Blue Defense's written reviews are positive against 94% of Bimza Slots's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Blue Defense ships an update every 3 months, Bimza Slots every 5 weeks. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
