These games are so much fun and there are bonuses everyday. HOWEVER, your challenges are too difficult and RARELY winnable. At this point I am beginning to believe that one can only win a challenge if they purchase what is needed to win. I LOVE your games but as of now I will NOT play the challenges. Update: I was wrong... I purchased some things and the challenges even got more difficult. I have now successfully stopped playing the challenges and feel less stressed!11/17/21
