Swedish MMO and social network platforms developer Playdo AB announced that Spineworld, its non-violent fantasy MMO targeting younger gamers aged 11 to 15 years, has reached three million registered accounts.

The company attributes this milestone to its marketing campaign coordinated with online game site Miniclip, which Playdo says helped grow the game's user base significantly last spring through early summer. The campaign accompanied a redesign of Spineworld's interface and the introduction of new features.

The MMO currently receives over 600,000 monthly visitors from more than 100 countries, with most coming from "North America, Western Europe, Brazil and some countries in Asia and Australasia". The developer says that its audience is an almost 50/50 split between boys and girls, and that 63 percents of its users are at least 13 years old.

"We have very exciting plans for the future of Spineworld,” says Spineworld producer David Nisshagen. “This milestone of three million accounts is the foundation of the next level of gameplay in Spineworld. The roadmap contains nurturing, magic, and user created content; all resulting in the vision that the player’s in-game actions are deciding the future of Spineworld."
