While being in the "genre" commonly known as casual games this game brings tricky, thoughtful and fun hours of gameplay with it.
Your task is to plant all sorts of flora in an attempt to defend your house that is keeping your juicy brains safe from the many kinds of zombies that just happens to stumble in to your backyard. This game is an addictive one for sure, but nothing less is to be expected from PopCap ofcourse.

I had great fun playing through this game, some stages can get very hectic. The different descriptions for each zombie type and plant in the game is a really nice touch too. With the big number of plants to choose from there's room for different strategies which is great for replayability.

It's possible this will get more than 6 entries.
