What Roblox game was the first to reach 1 billion visits?

The Roblox game that was first to reach 1 billion visits was MeepCity.

MeepCity, created by Alex Binello, was released in February 2016 and became one of Roblox’s most visited experiences. It passed the one-billion-visit milestone in late January 2018.

Roblox recognized the achievement in its 2018 coverage of the platform’s top games. The milestone referred to total visits, meaning accumulated game joins, rather than unique players or simultaneous users.

Adopt Me!, Jailbreak, and Brookhaven later became major Roblox successes and each accumulated very large visit totals. They were not the first Roblox games to cross one billion total visits. MeepCity is therefore the correct historical answer.
