That's according to developer Rovio's co-founder, Joe Wee. He told The Sun:
When it was released last December Angry Birds made a slow start but as word got round, everyones gone crazy for it.
We are also releasing it on Nintendo DS, Sony PSP and PS3."
Angry Birds has sold over 2 million copies to date. The aim of the game is to catapult birds into structures, using physics and special abilities to help them collapse.
Honestly, as much as other people like Angry Birds, we think it's a bit rubbish.
