Unfortunately this doesn't feel good enough to even justify playing a full game.
- The puzzles it's serving don't look very interesting or well-constructed. Are they randomly generated or from some existing puzzle DB?
- I'd really like to navigate the grid with arrow keys, not just by pointing and clicking.
- The app doesn't allow changing an already entered number, only undoing it.
- There's no support for pencilmarks that I can see. That's an absolute requirement for a digital Sudoku implementation.
- The app doesn't allow selecting multiple squares (for modifying all of them at once, or just for visualization).
Sorry if this sounds harsh, but the problem is that by making a Sudoku app you're setting up a comparison to all the existing ones. Apps like SudokuPad have amazing ergonomics, a ton of features, and a seemingly endless number of expertly crafted puzzles. It's not a comparison you can do well at. Picking a different type of puzzle with less competition might work out better.
- mbb70 3y agoThe sudoku logic is very simple: https://github.com/alabhyajindal/sudoku/blob/main/index.html#L278 https://github.com/alabhyajindal/sudoku/blob/main/index.html... An empty grid is randomly filled in till it's solved, then a fixed number of cells are randomly cleared. Thus it's very possible to create an ambiguous solution. However I don't grade it against every sudoku app in history, I grade it against other handcrafted index.html sites. And on that metric I think it's pretty good. Lots of room to extend functionality of course, but it seems like a project whose value was in the making, not the having.
- imglorp 3y agoMy first game had an ambiguous solution not resolvable with logic. It was one of these deals: a.b ... b.a On the plus side, I like that it highlights the current number. For a mature exploration of this idea with many more features, look at https://www.sudokuslam.com/ https://www.sudokuslam.com/ for ideas. I've been playing that one for many years.
- alabhyajindal 3y agoI will improve the puzzle generation function so there's only one possible answer. Thanks for sharing Sudoku Slam, looks great! Especially the "auto-fill in obvious numbers".
- imglorp 3y agoYes autofill, which feels like cheating, along with automatically filling in marks. What this does, though, is let you focus on only the hard decisions and the auto does everything else for you.
- alabhyajindal 3y agoThank you! Yes, I made the game because I enjoy playing Sudoku and wanted to implement one myself, just for fun!
- alabhyajindal 3y agoAll your points are valid, except that I'm not trying to compete with other online sudoku games. I enjoy playing sudoku and wanted to make one for fun. Based on everyone's feedback it seems that keyboard navigation, overwriting incorrect answers and better puzzle generation are the top missing requirements, which I'll add next. Thanks for your feedback!
