Update: Well as of Saturday evening all of the Rovio related Windows Phone games are back to .99 cents. Not sure what the deal was this morning with the free offerings. Hopefully you grabbed them while that was the case.

Nothing like a good deal and an even better deal is a free one.

According to Windows Phone Central, which I learned about via a tweet from my friend @MasterDevwi, two of the Angry Bird games for Windows Phone have joined the ranks of free.

With these two additions that means only two Angry Birds games on the Windows Phone platform have to be purchased.
