# Roblox vs Agar.io

The clearest difference is ads: Roblox at none against Agar.io's shown. Roblox also leads on review sentiment (60% vs 28%) and ratings volume (21M vs 221K). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Roblox sells 4 in-app purchases, starting at $4.99 per month and Agar.io sells 10 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Roblox against 4.5 for Agar.io. That said, the two scores are not equally well evidenced: Roblox has 21M ratings behind it against 221K, so its average is the more settled of the two. Written reviews are what separate them: 60% of Roblox's written reviews are positive against 28% of Agar.io's.

Roblox ships an update every 6 days, Agar.io every 4 weeks. Both last shipped on November 1, 2026.
