Rovio's free-to-play 3D karting game Angry Birds Go! is out right now for iOS, Android, Windows Phone, and BlackBerry 10.
The game is the first of Rovio's bird-based releases to be available across all platforms in F2P form.
So, yes, there are wait timers and a premium currency all swishing around in front of you when you try to go karting.
You play as one of the aggravated avians here and start off as the Red Bird. You gradually unlock more birds as you complete the various challenges that are thrown at you.
Some of the challenges are straightforward races, while others involve your smashing up fruit, getting to the end of the track before a bomb goes off, or beating a fellow bird to get it to join your flock.
You can also buy Telepods (physical toy versions of the karts) and suck them into the game using some weird mystical magic.
Angry Birds Go! is out on all of the platforms listed above right this second. And it won't cost you anything to find out if it's something at which you are prepared to throw money.
