I loved this game but will never use this one again. I had made it through several levels when all of a sudden. it just went back to level one so I had to start over. I hated the ads so I purchased the ad free version and got all the way up to silver grandmaster. Then ads started again. Next thing I know, the game reverted back to level one. I uninstalled and gave up after that. Great game but too many glitches.
