# Roblox vs slither.io

The clearest difference is rating: Roblox at 4.5 against slither.io's 3.8. Roblox also leads on ratings volume (20M vs 3K) and chart position (#1 vs #40). slither.io's advantage is iOS requirement (12.0 vs 14.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and slither.io sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Roblox holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 3K, so its average is the more settled of the two. Written reviews point the same way: 60% of Roblox's written reviews are positive against 55% of slither.io's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
