I enjoy this game. No problems playing on my phone. I've seen reviews about how you have to spend money to really do anything in the game and I disagree. I have never made an in game purchase. I participate in challenges and events and log into the game about once per day. I've always won speed-ups and other items to keep play going for awhile. If you don't want to make in game purchases you just need a little patience until you get to the higher levels and you obtain more rewards.
