In a move to improve its computer games offerings in Europe, RealNetworks has agreed to acquire Dutch game developer Zylom Media Group.

RealNetworks will pay €21 million for Zylom, which develops so-called "casual" games for PCs, such as easy-to-play word, puzzle and card games, RealNetworks said.

Customers can buy and download Zylom's games from its website or through premium services provided by AOL, Wanadoo and Yahoo. Its game library includes 70 localised games in seven languages, including Mirror Magic and Hotel Solitaire.

Based in Eindhoven, Zylom reported sales of €6.7 million for 2005, and net income of €620,000.
