Magic Sudoku 4+

I tried it on my computer screen and on paper. It didn’t work most of the time. Sometimes it changes the puzzle-numbers while it’s scanning. Sometimes it’s doesn’t capture the image. Other times it’s out of focus, and there is no way to focus the image. I tried different orientations to the paper. I had it on the table, on the wall, and in my hand, but this didn’t help. From time to time, I got the solution, but most of he time I didn’t. It sometimes recognizes the 1 as a 4.

The app needs more work.

v1.3 is coming out today that adds support for many more fonts and puzzle layouts! Please give it another shot and report back.

If it's still not working please message pictures of the puzzles to our support team and we'll add them to our training algorithm for the next update.

Update: We've added support for many more fonts and puzzle layouts in recent versions. Would you mind testing it out again and seeing if it's working any better for you now?

I tried it on three different Sudoku's on my iPad and Mac, but in none of the cases it was able to read the numbers correctly. Most of the time the numbers were mismatched, reading a 3 when it was an 8 or vice versa, if it did read the numbers right, it paced them in the wrong spot. From the 30 or so attempts, it was never able to solve anything. It has great potential, but it needs a bit more work placing the existing numbers in the right places.

Update for 1.4: Still no luck with any sudoku on a screen. Paper versions worked quite OK, occasionally the numbers are upside down.

Update for 1.7: No improvement at all when aiming at a Sudoku on an iPad screen. As requested, I have send an email to the developers.

Bummer :(

v1.3 is inbound shortly (should be out later today). We trained on many more user submissions so it should work a lot better on a wider variety of puzzles!

If that still doesn't help please message our support team with pictures of the puzzles it's struggling with and we'll add them to our training algorithm for the next version.

Update: we've made several improvements in recent updates that should hopefully help with this. Could you give it another shot and let us know if it's any better for you? (And if not please let us know so we can keep working on making it better)

Has to absolutely flat to scan, so doesn’t work too well with newspapers. Also when it’s perfectly flat it flickers between scanning and finding a sudoku and takes a while to scan. It then scanned one upside down and didn’t solve it.

Good news: we have fixed many bugs with version 1.1 which should come out at any
moment once Apple finishes reviewing it. It will fix the upside down puzzles for sure.

Can you contact our support team with the puzzle you we’re having trouble scanning? We tried to add as many puzzle formats to our learning algorithm as possible but there are more non-standard ones floating around out there than we realized. We are working on improving the app to work with more and more puzzle layouts every day!

Update: We've been hard at work improving the app. It should work much better on puzzles that aren't flat on a table now. And we have also added support for more puzzle layouts (especially in some popular newspapers but admittedly that's still an area we are working on improving). Is the latest version of the app working any better for you?
