There never used to be ads on the daily challenges, and now they are both before and after each board. They aren't the quick flash ones either, but timed ones that take between 10 seconds to a minute to allow a skip. It's turned a game that was fun and relaxing to drop in and out of when you've got a few minutes, to having to spend more time watching ads than actually playing. really disappointed.

Fab app, clear, easy to use and I like the customizablity. The only thing I find annoying is that it automatically removes pencil marks once that number has been added to the row / column / square (e.g if you have pencil marks that a cell could be 5 or 8, and then you subsequently put a 5 somewhere else in the row, it will automatically remove the pencil mark 5). I realize that some people might like this, but I wish it could be a setting to turn it on or off. Otherwise great though!

This is game was brilliant, as every other game like this bombarded you with ads, and some you couldn't skip, so 3mins of your life was wasted!! This game/app was highly recommended, and was advertised as "NO ADS" so like everyone else, I downloaded it and played it regularly as it was peaceful!! Now they have updated the game and ads are forced, it says in the description, this can be turned off, yes it can, ONLY if you get premium and pay a recurring monthly subscription!! No thanks!
