Sure. It helps pass the time. I bet a lot of people are going to react to this--but I like Angry Birds. At first I thought it silly, but it really is entertaining. My cousin introduced the game. I've downloaded it to my phone.
It all depends on what phone I have, but honestly HELL YEA! They kill the time when you need to wait for hours!
I install only games that doesn't require much graphics, i usually play high graphics games on my pc or ps3, I play sudoku, some motion sensor games, or mind boggling games
