Am deleating, I enjoyed the first few games. Absolutely love these type of puzzles. But after 4 games you need stamps, yes I looked and you can get so many free, them earn by data share for adds. In my view it is not a free game then. If I have to 'earn' stamps. Basically you want me to watch extensive adds to play a free game. Nowhere can I find how many stamps are needed per game. But feel sure 3 stamps is not going to get me far. Disgusting, con, not free,
