The animation is excellent, but it's a pay to win game. You can complete the daily challenges only if you pay for more rolls but that too doesn't guarantee you complete the challenges. When the first album was open there were awesome rewards for completing albums, challenges and there were more stickers in sticker packs. But when the second album became active all the rewards have come down especially rolls in challenge missions and less stickers in sticker packs Gets Unfair with each new album.
