This was the suduko app I was looking for. I love it. Unfortunately when invisible ad windows get in the way of gameplay that gets really frustrating and annoying. I kept trying to use the pencil tool but an ad was laid right over it preventing me from doing anything until I closed it. Unfortunately after I closed it it came back within 30 seconds. If this persists I will probably lower my review and perhaps stop playing the game.
The game is a good one by itself and I've had it installed and played it to completion before. The ads used to be ok but they've now included ads that automatically turn up the volume and start playing on completion of a board. While they do have a speaker you can sometimes use to mute the ad ( it doesn't always work ) it disturbs everyone within 20 feet and if you're playing at night it will startle people awake. It's no longer worth the hassle. There's lots of good soduko games available.
I'm with the other reviewer who said the ads have been increasingly resembling malware, with a pop up internet window stating "CONGRATULATIONS! You have won..." blah blah. Prior to the annoying malware the pop up ads were something I could deal with. You should have an option to pay for an ad-free version as this would easily be a 5 star app l.
Would have got 5 stars but for the incredibly annoying and intrusive pop up ads that keep appearing mid game in a browser window that proves very difficult to get rid of. Fully understand why we get ads before or after a game but please - not in the middle..!
Besides the random advertising I love this game. The ads only pop up in between games so it doesn't get in your way except when it forces your Web browser to open... I really don't appreciate that aspect of the ads I've been getting.
To much lag between adding numbers. If it's a timed game then you should be able to immediately touch the next square to add your number but you can't because it has to do its fancy display everytime you add a number. Very cool app just fix the lag and that's only because it's a timed game.
