Ratings and reviews

I want to love it, this is exactly what I wanted to practice different techniques. But the interface is just.... Bad... Too many steps to add a number. Ideally let us select the number first and place it with 1 click after that. Also a bit hard on the eyes compared to other sudoku apps (the good ones without ads, that is).

I've owned the PC version of this game since the early 2000s. My only criticism with this version is the inability to remove the displaying of pencil marks. That feature is called "Erase All" in the PC version. If that were available I would give give stars. I don't see this change made in this latest revision. Disappointing. Made in the latest revision. Five stars! Thank you for the revision.

This app has helped me so much, but I really think it needs a highlighter option? The chains are extremely difficult to see in your head without it. Maybe 4 different colors you can highlight squares to help with that. Once you get to chaining, it is almost a necessity.

What’s new

Version 2.0!
Added a touch sensitive number bar for quickly highlighting any number in the puzzle. Also highlight pencil mark pairs for easy spotting of XY-wing and naked pairs.
Added ability to hide Technique details.
