Zynga’s hugely successful Words With Friends and Draw Something games have launched on Windows Phone.

The two titles are available in ad-free form for $2.99 / £2.29 from the Windows Phone Store, although early feedback from users is proving somewhat mixed.

“Dave”, who gives Draw Something a one-star rating on the Windows Phone Store, writes, “Poor version. Keeps crashing, doesn’t work too well and doesn’t make use of WP interface.” Meanwhile, “Paul” says of Words With Friends, “Nice to finally have this for WP7. But several features such as incoming chat don’t work, and it’s very slow to play.”

A free, ad-supported version of Draw Something was released for Windows Phone in October, although the app was then pulled, according to Windows Phone Central.
