The goal of this project is to gamify geometric challanges. We use the GeoGebra software for this. This game is MIT licensed; see the LICENSE file.

Kasper Peulen's brilliant game has been borrowed and rehosted at https://euclid.findell.org. We have squashed bugs, improved the GeoGebra functionality of the apps, made some edits, and added new levels.

Notes:

• The key idea behind this site is javascript code that tests whether GeoGebra objects have been drawn. For the current version, see the file _includes/testobjects.js.
• The source code requires Jekyll, a simple, blog-aware, static site generator. See https://jekyllrb.com/docs/installation/.
• After Jekyll is installed, from the main directory the command jekyll build will build the site in the subdirectory _site.
• The command jekyll serve will serve the site locally for debugging.
• The command jekyll serve -d _siteE --layouts _layoutsE will build the site (in subdirectory _siteE) with layouts that omit the navigation menu and the footer.
• At one point, there were plans for an iOS game. See https://www.facebook.com/euclidthegame.

A year ago I posted the idea for this game at stackexchange: http://math.stackexchange.com/questions/373672/about-euclids-elements-and-modern-video-games

I hoped that I could inspire game developers to make such a game. Well, I failed! But I did inspire myself to learn a little bit about html/javascript and geogebra, and in this way, I was able to make this game.

If you have worked with geogebra, it may be not so hard to contribute to new levels. I've written a couple of functions that make it easy to test if objects/lines/circles are drawn.
