Had to uninstall. far too many ads. I did enjoy the riddles but it is too frustrating having to deal with an ad after every single riddle.. Spoils it.. I had originally rated 5 but I am changing it to 1. I did read your reply to a review similar to mine and yes free games do have ads but yours is rediculous.. 10 seconds to solve a puzzle followed by 30 seconds of ads.. Why would I therefore pay to remove ads when I wanted a free game. I think you are spoiling it for yourselves cut back on ads!
