This game is actually really fun and quite addictive. Which I HATE because it screws me everyday!! If game feels like it, it will allow to match 1 bubble, but only if it screws you. When you get into the higher levels (3000+), it consistantly doesn't give you birds when you match 4 or more, but only if you are LOW on moves. There are many little quirks the game uses to its advantage to force you to waste moves. I refuse to spend even a dime on this game if it's gonna continue to be so shady....
