Game broken

When attempting to access this at https://githubschool.github.io/github-games-tierib, I am getting a 404. This could be caused by a couple things:

- GitHub pages needs to be enabled on master. You can fix this in the repository settings.
- the index.html file is incorrectly named inde.html. We will fix this together in class.

Can you please fix the first bullet @tierib?

Open the repository settings and check that GitHub Pages is enabled on the master branch. Confirm that the linked GitHub Pages URL no longer returns a 404; the issue specifically requests the first bullet, while the index.html naming problem is noted separately.
