URL in description and README broken

The URL in the repository description and README are pointing to githubschool's copy of the game instead of yours.

Please fix both so they point to your copy of the game at https://githubschool.github.io/github-games-ameerkhan90

Check the repository README and the GitHub repository description, then compare both URLs with the issue's target URL. Update both references so they point to the repository's own game copy, and confirm the README link and description no longer point to githubschool's copy.
