Of the overall playerbase, which includes players from over 200 countries, 40 per cent of the game’s users are female.

In celebration of the milestone, Roblox is giving away a free virtual gold bar shoulder accessory to users.

“We started Roblox over a decade ago with a vision to bring people from all over the world together through play,” said Roblox founder and CEO David Baszucki.

“Roblox began with just 100 players and a handful of creators who inspired one another, unlocking this groundswell of creativity, collaboration, and imagination that continues to grow.”

This latest achievement follows Roblox hitting an estimated $750 million in revenue on mobile ahead of its launch in China this year.
