# Octopus Evolution vs Slime World

The clearest difference is rating: Octopus Evolution at 4.8 against Slime World's 4.1. Octopus Evolution also leads on review sentiment (93% vs 60%) and ratings volume (4.1K vs 64). Slime World's advantage is update cadence (every 2 weeks vs every 6 weeks) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Octopus Evolution sells 10 one-off in-app purchases and Slime World sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Octopus Evolution holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Octopus Evolution has 4.1K ratings behind it against 64, so its average is the more settled of the two. Written reviews point the same way: 93% of Octopus Evolution's written reviews are positive against 60% of Slime World's.

Octopus Evolution ships an update every 6 weeks, Slime World every 2 weeks. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
