Great fun, keeps me occupied when I'm bored. I just play it over and over. As the game progresses it gets harder and your choice of plants increases so you have to think about what you are going to do. The notes from the zombies add a bit of humour. Some levels are quite difficult so a child would probably need help (it has a 12 rating) but there has to be a bit of a challenge or it would be boring. I love it.
