The free-to-play online game service Gameforge now has 300 million registered users.
The last 12 months have been a period of tremendous growth for the German company.
In an interview with GamesIndustry.biz last August, CFO Christoph Jennen articulated plans to "press ahead with acquisitions" and recruit around 100 new staff. A further 100 million users have joined the service since then.
"Our current focus is on process optimisation and consolidation, but our growth continues to progress unabated", said Jennen in a statement.
"Although we are incredibly proud of this milestone, we are still motivated to continue our exponential growth. We are strategically expanding our portfolio and are looking for new staff - in Karlsruhe alone we currently have around 100 open positions."
Further growth is expected from the release of the browser game Star Trek: Infinite Space, which is due before the end of the year. The company claims it, "will mark a new era for the genre in terms of visuals."
