Think it works great. Did everything I expected and more.
Purchased for the Sudoku docs section. Can't really play Sudoku with this app. Help\about goes to Bowman's Bingo, not a help file...
Best strategies guide ever !
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.
Awesome app. Just like the parent site that spawned it, this app has a lot of cool features that any Sudoku fan, beginner or expert, is going to love.
I love how it takes a step at a time rather than solving the whole puzzle at once. My only gripe is I often do puzzles of different sizes than the standard 9x9, and I wish I could change the size of the puzzles.
The tutorials are a great way to learn more advanced strategies. I'd love to use the sample puzzles to practice applying them but the interface is terrible. Needs a way to pencil in only one number, a way to select a number and pencil it into several cells, and an option to automatically eliminate candidates when you finalize a cell. See Genina's Soduku Free for a great interface.
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 PlayStore'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.
I would love it if the digits were actually as large as the photos imply. In reality they are tiny and damn near impossible to see. Accessibility options for vision impairment are surely a basic these days? And I see from other reviews that people without vision problems say the font is too small. App is unusable for me sadly. Uninstalled, refunded.
Fonts are microscopic on phones. They are barely readable and don't come close to filling the squares. The rest of the solver, just like the online version, are AWESOME!!!!
