Huh, I just made a pretty similar game a couple weeks ago.

Mine is different in that it it's way less polished, starts with a randomly-initialized grid, and rows/columns that are all the same color disappear (so the goal is to make them all disappear).

It wasn't quite fun enough for me to clean it up more, but it was mildly amusing for a while. It's here in case anyone would like to try: https://rawgit.com/zwegner/switchy/master/switchy.html (or the source repo: https://github.com/zwegner/switchy)

Doesn't work for me. I'm clicking the blue square and nothing happens. Chrome 37

Ah, yes, I had forgotten that I didn't test in anything other than Firefox. I'm very much not a web developer--working with JS is really quite a pain, and I had to use as much ES6 magic as possible to make it tolerable. Looking now into Traceur to de-ES6ify the code...

OK, so it's fixed now. Tested in Firefox, Chrome, and Safari. As soon as rawgit refreshes its copy, the new version will be live.

It's fun :)
