SpineworldPlaydo AB, a Sweden based casual gaming house, has raised $4.3M financing round led by Miniclip Ltd. and Northzone Ventures in December 2008 (via). Playdo has been creating casual games since 1999 and has also entered the market for virtual worlds with Spineworld, a game released in April 2008. The financing was organised by GP Bullhound and will be used for development of Spineworld,  as well as marketing and sales of the game.

Eventhough Spineworld is a relatively new game, it already has some one million registered users. It is distributed through Miniclip. Miniclip is one of the most famous casual gaming sites in the world and thus explains the success behind Playdo’s games. The business model behind Spineworld is simple, users pay a €3.95/month membership fee which gives them access to quests, virtual goods, and other features in the game.
