 This repository contains two versions of Sudoku :
-- A single-player version, used as a starting point for the [tutorial](
-  https://concordant.io/tutorial).
-- A collaborative version, using the Concordant platform API.
-  This is the outcome of the tutorial and can be tried on our
-  [sudoku demo page](https://demo.concordant.io/c-sudoku/index.html).
