Starts off quite entertaining with enough challenge but not too much, and picture searches add variety. But after a few days and 80 levels or so it became impossible to progress without boosts, which soon ran out leaving coin purchases the only way to continue with anything. Paid for one lot which bought a couple of levels but could see it was going to eat into the pocket cynically to do any more. Shame, it could be fun but ruined by addictive devices.
