Best app by far

After playing this free app every day for four years, I figure it's time for a review. If you love sudoku or you want to learn to play, this app has everything you need without being cute or fancy. I play in the night screen day and night for less eye strain. And I also play at the highest level with no hints. The games seemed to get tougher about six months ago so you know the developers are always improving. Or else I'm older and slower! There are ads running along the bottom, but they are easy to avoid. And even if you accidentally touch one, you can X out of it right away and get back to your game. This is the first and only sudoku app I've downloaded. I haven't felt the need to look for another one in four years. It's a straight-up game that has stayed challenging and even addicting!

This is the one!

This is the sudoku app I’ve been looking for! There is so much about this I love! You can choose from the many options to make this 'just right' for you. It is intuitive and easy to use, and even offers a landscape option. An added bonus is the jigsaw sudoku. I haven’t seen it offered in the other apps, so I was pleasantly surprised to find it here. I’ve tried a lot of versions of sudoku, and this is my new favorite😀

LOVE the Jigsaws but...Problem fixed!!!!

The prompt response of this developer is rare and greatly appreciated! I wrote a review mentioning the pencil marks could not be seen in the darker jigsaw puzzles. The developer responded immediately and today, less than a week later, the game updated and the problem was fixed😃! This is the BEST sudoku app I have tried and the only one to offer the challenging jigsaw puzzles!
