Capture the Flag

White Flag

There are 6 secret flags scattered across this website. Can you find them?

A flag looks something like this: GXYZ{***********}. If you manage to find one, feel free to send me an email with a short writeup, and I will proudly add your name to the "Hall of Fame". Or do it yourself by editing this page and opening a pull request! I will add more flags over time, so check back later for updates.

This challenge is about learning new things and having fun. If you're stuck and need a hint, just let me know. Also, if you have an idea for a new flag, I'd love to hear it!

Disclaimer: Cheating is easy, and this website is open source. Please don't ruin the fun for yourself, and keep your eyes off the GitHub repository! :)

How do I add a badge to my website?

A badge is comprised of two variables: The color and the number of flags.

For color, you may choose blue or orange.

The number of flags should correspond with the flags you've found on this site.

Paste the following code snippets to your site. Make sure that you've replaced all the variables!

Custom badges

You can also use shields.io for more flexibility with the design of the badges. If you don't want to rely on a third party to host these badges, you can also download and host them alongside your website.

If you don't have a website (or don't want to add a badge to it) but still want to support this challenge, you may also post your progress and a link to the site on social media. This helps other people discover this challenge!
