Online games company Roblox is hoping to raise up to $150 million through share sales.

The news comes from PitchBook, which reports that should the company raise that figure it would value it at $2.4 billion.

It was noted however that the terms of the deal have not been announced and thus can be subject to change.

Under block and key

Roblox lets players create their own content and get paid for it, racking up more than 60 million monthly active users in the process.

The build ‘em up game originally launched way back in 2005 and came to iOS and Android in 2012. The user-generated content-focused game has become hugely popular across platforms.

Former Apple Asia-Pacific GM Chris Misner was recently named as president of Roblox International in May to help further expand the popular game around the world.

“Roblox is poised to unlock a large global audience,” said Misner at the time of his appointment.

“It’s already played by English-speaking kids in over 40 countries worldwide. By making the platform more accessible to Spanish speakers, we’re taking the next steps to power the imagination of players everywhere.”
