What was Slither.io’s peak?
-
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.
-
-
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.
-
-
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.

-
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.
