The company said its market capitalization has quadrupled in the past 2.5 years. Alawar was founded in 1999, and its games are available in 60 countries. It has published 200 casual games, including Farm Frenzy, Craze, and the Treasures of Montezuma. This year, it plans to enter the social game and massively multiplayer online game markets.
