Draw Something has been available for a couple weeks now in the Windows Phone Store, and users have been grumbling about the apps poor performance. Zynga has updated the app today to version 1.0.13, but they did not include a changelog. Based on the reviews they were receiving we can guess that this is mainly a stability and performance update, much like Word With Friends received last week.
This update is only for the paid version of the app. Lumia owners using the free version will have to wait a little longer. Hopefully these improvements will make the $2.99 sell a little easier.
