# Aliens in Chains Space Puzzle vs Bloom Sort

The clearest difference is review sentiment: Aliens in Chains Space Puzzle at 72% against Bloom Sort's 16%. Aliens in Chains Space Puzzle also leads on ads (none vs shown) and iOS requirement (8.0 vs 12.5). Bloom Sort's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (2.8K vs 25). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Aliens in Chains Space Puzzle sells 10 one-off in-app purchases and Bloom Sort sells 23 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Bloom Sort holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Bloom Sort has 2.8K ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 72% of Aliens in Chains Space Puzzle's written reviews are positive against 16% of Bloom Sort's, so the app with the better star average is not the one people write more warmly about.

Aliens in Chains Space Puzzle ships an update every 3 weeks, Bloom Sort every 4 days. The most recent releases landed on October 26, 2026 and October 22, 2026 respectively.
