What was Slither.io’s peak?

  1. Launch and viral growth (2016):

    • Slitherio was released in March 2016.

    • It very quickly became a viral browser + mobile hit, helped by coverage from YouTubers and social sharing.

  2. Downloads & adoption at peak:

    • In Q2 2016, it achieved ~80 million downloads worldwide across iOS + Android. 

    • In May 2016 alone, it was topping the download charts in the U.S. across both Apple and Google platforms.

  3. User engagement & revenue:

    • At its height, Slither.io was said to have ~67 million daily browser players along with tens of millions of mobile installs.

    • The developer reportedly earned over $100,000/day or more during peak times. 

  4. Cultural footprint:

    • It was the most Googled game of 2016, ahead of Agar.io and other big titles. 

    • The browser version was among the top visited sites as well. 

So, peak = extremely high downloads, huge daily players, big revenue, massive visibility in 2016.

What is Slither.io like now (2025)?

Here are some recent data points to approximate current popularity.

  1. Daily players / active users:

    • MMOStats estimates Slither.io has about ~35,000 daily players in 2025. 

    • This is much lower than reported peak figures. (We don’t have exact browser-daily numbers now, but current numbers appear smaller by orders of magnitude.)

  2. Traffic / search interest:

    • In July 2025, Ahrefs reports Slither.io had ~6.7 million visits from search traffic during that month.

    • The domain rating and backlink profile remain strong (Domain Rating ~72) indicating persistent SEO strength.

  3. Install base (Android):

    • The Android version still has over 500 million installs.

    • However, number of new installs, active retention, and daily engagement are much lower than during the surge in 2016.

  4. Monetary and cultural presence:

    • There’s less news of big revenue spikes lately. The game no longer dominates charts.

    • On Twitch etc., its visibility has dropped; Slither.io isn't among top streamed or discussed games.
