Do not play this game! Got it for a challenge from an offer wall for other games. I played to the specified stage to get the prize while enduring ad after ad, but it was a scam. Not only did I not receive the reward, the offer is now listed as invalid even though I still have a month to finish it. Asked for reason or anyone to reach out to but the teams just ignore me. Don't fall for this nice looking reward. You will just waste your time.
