This is an excellent tool for showing strategies and explaining the reasoning within the step. Few solvers do this, and even fewer have this many methods implemented. I have two recommendations. One is to allow the user to select the order in which algorithms are tried, not just which ones to use. I have found a couple of puzzles where the solver gets stuck when it solved a step using a method earlier on a list when another would have opened up more possibilities for eliminations. A couple of unsolvable puzzles aren't so unsolvable with a bit of manual input that simply substitutes a method. Another is to implement more purely mathematical solving methods. Pattern recognition should always be the first place to go, but there are some human computable algorithms that while often used in computer sciences, can be done on paper within the limited scope context of sudoku cells. I know not everyone wants to delve into abstract algebras, but in reality many of these patterns could be summed up in such terms anyway.

Love it EXCELLENT app! I am beyond satisfied with it. Errors... Sample Puzzles. Riddle of Sho to Escargot are mislabelled. Escargot shows up in place of the Inkala. Also, X-Wing's last 2 examples have no images. One more thing. I initially bought app through Amazon, but an older version is sold there, so I had to buy the Play Store's separately. The older version does not have the above errors but lacks the tremendous amount of sample puzzles. App needs to be THOROUGHLY brushed up once more but still remains pure gold.

Use this solver to learn and understand. Learned and enjoyed Sudoku ever since I came across this solver many years ago. I especially like the step-by-step solver. Wish I had the android version then since I like doing Sudoku while travelling. Was happy to finally see the app when I went back to the site to solve one puzzle. Just have to show my appreciation and support.

It's a start Recent update fixed issue with core strategies causing it to crash. Note it just crashes at the end of a game

Great wiki! But not so great app, there are some problems with it. When one is stuck somewhere and has to type all the numbers, it is so much easier on the web app than on this app, because it gives you a normal num-pad to type - just the usual 1 2 3 / 4 5 6 / 7 8 9 layout. And not this - 1 2 3 4 / 5 6 7 8 9 layout from the app. Hard to get used to... also it shows code (i.e. "/
") in the text sometimes, and there are no docs page for some strategies like simple coloring

Crash in Galaxy Express Crashes when I press the pencil button at the bottoms left. This takes a lot of functionality out the app, unfortunately.

Abandonware, apparently. Won't show in app store with an Android 14 device. Too bad as it is a fantastic way to access the sudokuwiki content.....
