# Space Marshals 3 vs Impossible Space

The clearest difference is rating: Impossible Space at 4.6 against Space Marshals 3's 4.1. Impossible Space also leads on iOS requirement (10.0 vs 13.0). Space Marshals 3's advantage is ads (none vs shown) and review sentiment (62% vs 39%). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Space Marshals 3 sells 8 one-off in-app purchases and Impossible Space sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Impossible Space holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 738 and 1.5K respectively. Written reviews complicate that: 62% of Space Marshals 3's written reviews are positive against 39% of Impossible Space's, so the app with the better star average is not the one people write more warmly about.

Space Marshals 3 ships an update every 9 days, Impossible Space monthly. The most recent releases landed on October 27, 2026 and October 22, 2026 respectively.
