I can't begin to describe how dull this game is. It is not challenging in any way. Some of the levels can be won by pulling all of the pins in any random order, which means my cat could probably play it. And way too many ads. I get that the creator wants to get some return for their efforts, but an ad at every opportunity is just being greedy. "Congrats. You have won a gift" That gift is to watch another ad. Yawnarama!
