This is an implementation of Donald Knuth's Algorithm X to solve Sudoku puzzles using Dancing Links.
This started as an investigation into whether you could solve a problem (e.g. a Sudoku Puzzle Solver) without fully understanding the problem (in this case without knowledge that Sudoku puzzle's being an example of a mathematical problem that can be solved as a type of problem called 'exact cover').
TL;DR; No. You might get close, you might end up with something that partially works, but in most cases, no.
I wrote a number of articles about my experience implementing a Sudoku Solver, which you can read here:

A version of the code in this repo is deployed as an AWS Lambda, and is invoked via the React app on this page here: http://react-sudoku-solver.s3-website-us-west-1.amazonaws.com/index.html
