Seems more frustration than fun.

Its fun to play however having to see a pop up or ad every 10 seconds is really annoying and obtrusive. The only other complaint I have is that you have to keep the dash in the middle of the circles. You cant circle around the ring and come back to a spot. Thats a little annoying.

Hats also seem pointless. Its called "Pop the Lock" not "Pop the Circle with the Baseball Cap"

Other than that, its pretty enjoyable.
