Flash games recommendations and best websites for those?

Hello, I am currently playing Plants vs. Zombies online and it works like a charm, so I was wondering if anyone here knows any good websites for those and what games are playable with the Playbook.

The link for the online version i'm playing is the official Popcap games website at Plants vs Zombies™

That one, Facebook and newgrounds.com are the best ones i know.

Edit: Oops I realized I opened this in the wrong forum, could a Mod please move it to PB Apps and Games? Thanks and sorry for the trouble.
