Verdict
The clearest difference is rating: Agar.io at 4.5 against slither.io's 3.8. Agar.io also leads on ratings volume (221K vs 3.3K). slither.io's advantage is ads (none vs shown) and review sentiment (55% vs 28%). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Agar.io sells 10 in-app purchases, starting at $7.99 per 7 days and slither.io sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Agar.io holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Agar.io has 221K ratings behind it against 3.3K, so its average is the more settled of the two. Written reviews complicate that: 28% of Agar.io's written reviews are positive against 55% of slither.io's, so the app with the better star average is not the one people write more warmly about.
Agar.io ships an update every 4 weeks, slither.io weekly. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
