I like the puzzles, but there are far, far, far too many adverts, including obtrusive audio ones that can't be muted without leaving the puzzle. I understand, the ads pay for the game, but the balance is too far against the user. It's every minute. I'd be happy to pay for an ad-free version, but when I looked for an ad-free option, Google play wants me to agree to something, without telling me what I'm agreeing to.
