# slither.io vs Alien Blob io

The clearest difference is rating: Alien Blob io at 4.5 against slither.io's 3.8. slither.io's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. slither.io sells 1 one-off in-app purchase and Alien Blob io sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Alien Blob io holds the better App Store score, 4.5 against 3.8. Both are backed by a comparable volume of ratings — 3K and 2K respectively. Written reviews complicate that: 55% of slither.io's written reviews are positive against 45% of Alien Blob io's, so the app with the better star average is not the one people write more warmly about.

slither.io ships an update weekly, Alien Blob io every 2 months. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
