I have to say with so many people talking about 509 as an uber hard level I was disappointed with how much of a little challenge it was. I have had harder levels than this one that baffled me longer. That said it does require a little bit of good luck. In your first 5 moves you will pretty much know if you have a shot at finishing the level. My suggestions are use whatever freebie help you can get to help at the beginning of the round. Silver coin cashout, daily rewards, video freebies etc. Do not overly concern yourself with the green piggies at first, work your way up to the top row so that you can uses the bottle throwers as much as possible. Horizontal rockets on the top row are nice. As the middle frees up you will have better chances at combining powerups and helping get rid of green piggies. Also the bottle throwers will help with that. Free up as many birds as you can by popping the angry red (and other colour red is most common) birds. You want to set off chain reactions as much as possible to counter the annoying pig that repairs piggies. It is for sure a hard round, but there are worse. It does require some good fortune at the beginning but it is for sure doable. Good luck to those stuck on it.
