Great graph game

Last week we took a break from combinatorics and I taught the students what graphs were, and a few terms related to graphs, and how to inspect very simple graphs for isomorphism (I hope I’ve used the correct word).
As a nice follow up, just for fun, and to give them a break, the next time we meet on a Friday (trips intervene) we will play this little graphs game, if I can get it to run on a set of laptops.
The idea is to get the lines not to overlap. Try it yourself, (click the image), but be forewarned, it is addictive.

Indeed, isomorphism it is. I’ve never seen Planarity before — it’s excellent!
Uh oh. This reminds me of the last puzzle game I got addicted to: reflections.
What a great puzzle. I could sit here for hours doing this.
