Peggle, PopCap's classic pinball puzzler, is currently free to download on PC if you have an Origin account.
It is the latest game to feature in EA's Origin On the House promotion, which gifts you a game to keep forever, no strings attached.
This is the original and best Peggle, too, although the sequel isn't bad either.
Will PopCap ever make another Peggle? It's been five years now since Peggle 2 - long enough then, although PopCap's output feels like it has slowed down of late. The developer is currently still supporting Plants vs Zombies 2, and there are rumours of a third Plants vs Zombies Garden Warfare shooter.
