Yes, this game is addicting. My grandma and sister play it. I've seen them play it all afternoon. And here I thought I played my real time strategy games for long sessions :)
My addiction happens to still be Tetris when it comes to puzzle games. I've been playing Tetris on just about every electronic device I have had that was able to play it since the game came out in the 80's. I've tried Chuzzle and I don't like it quite as well. The chuzzles remind me of those pom pom things with feet and googly eyes that were popular back in the 80's.
