Highly recommended

I downloaded this app on recommendation from a friend. Wary of annoying apps which purport to be 'free' and aren't - I thought I'd give it a try. I'm very impressed indeed. Of course, as expected there is advertising built in, however the adverts are mainly for other games and are easy to close after a couple of seconds and they always appear at the start or end of games or if you pause play. On my phone version of this app there is advertising at the bottom of the page but it's in no way intrusive.
This app worked well in a glitch free way, doesn't crash / lose your game mid play / do anything else annoying or unexpected. To this end I'd say it's very well designed and managed. There are options to change various aspects of play e.g. background colour. There are various levels of difficulty. I started off on the very basic 'breezy' level while I attempted to learn how to play. I've progressed through the various levels and had lots of fun in the process. In addition to extra options, there is a stats page and a very clear explanation of the scoring system used. The app also records your best and average scores. All in all a great little app. I highly recommend it. Thank you to the designers and well done on a great job done.

Love game but need bigger number buttons

This game is my favourite to pass an hour or so and keep the brain hands shake and am now finding it hard to hit the correct number with any speed as they are so close together and quite small...would really help people like me is you could spread them out a little more on the landscape view to give us a bigger area to aim for...thanks for a great version of sudoku...easy to see, helpful hints if you get stuck, and I like to try and beat my best times too xx

Great way to play

Lovely app and great way to play the game. The only thing that i would change is being able to turn off the clock as I hate playing any games against the clock. Good that there are not too many ads either.
