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!

This version of Sudoku is my favorite. I have been playing it every day for several years, and each version gets better and better. I love the simplicity of the design, the clean look, and all the features it offers. In addition, the Jigsaw puzzle version is a really fun variant. I’ve tried many other Sudoku apps and this one is the best. Highly recommended!!!

Stumbled on jugsawduko 15 minutes ago & enjoyed it, so I went to the App Store to find one for my phone and found this one. I love it so much that I don’t know how I can go back to regular sudoku. I deleted the other sudoku games from my phone. Still learning it, so I may have additional comment later.
