Zynga (ZNGA -6.2%), which sold off today thanks to a downbeat Cowen note, says it has acquired four small mobile game developers: Germany-based Gamedoctors, and U.S.-based HipLogic, Astro Ape, and Page 44 studios. Zynga's interest in bolstering its mobile offerings has led it to make rejected bids for Rovio and PopCap Games, and has also led to speculation it will try to acquire Glu Mobile (GLUU).
