My partner and I like to collaborate on the New York Times sudoku puzzles everyday. Recently, I had to visit my mother and we had no good way to do the puzzle. I decided to build this little app so that anyone can collaborate on a classical sudoku puzzle with their friends. I also built a sister chrome extension that converts the NYT sudoku puzzles into .sdk format: <a href="https://chrome.google.com/webstore/detail/new-york-times-sudoku-imp/ekhmjkmibekgoiodgnpbecpchpppjkhn" rel="nofollow">https://chrome.google.com/webstore/detail/new-york-times-sud...</a><p>The UI is basically identical to the NYT sudoku page except for the number pad which I'll be adding soon.<p>Hope y'all enjoy, if you want to boot it up locally or help me add features the source code is available here:<p><a href="https://github.com/davefol/sudoku-with-friends" rel="nofollow">https://github.com/davefol/sudoku-with-friends</a><p>and here:<p><a href="https://github.com/davefol/newyork-times-sudoku-importer" rel="nofollow">https://github.com/davefol/newyork-times-sudoku-importer</a>
