Enjoy!
I’ve been playing this version for years and I noticed that every now and then the difficulty levels shift dramatically. It happened again about two weeks ago. I used to be able to solve extreme level in average of 8 minutes (daily). In the last 2 weeks that level has become unplayable.
Finally paid (again?), but they deserve it!

I’ve played this version for years and moved it - or downloaded again - with every new phone or tablet. I’ve paid before, I’m pretty sure, but under a different email, so... But, I’m doing so again, not because the ads are annoying (honestly, I hardly notice them), but because it’s so inexpensive and more than worth the nominal fee to support the developers.
Love!!

I’ve tried many different sudoku apps and this has always been my favorite! I finally bought the app, not because I was sick of ads (there are not many) but because after years of deleting every other sudoku app but this one, they deserve the couple dollars they ask for. ‘Digit first’ is what it’s all about. As well as the simple, pretty design that makes the game easy to play and calming. Love!
