Omar Chehab from University of Toronto reached out to me over email (Steve@torontogamedevs.com!) to let me know about his "infinite puzzle game" IO Reboot is out on Android phones.

"Easy to learn, hard to master... IO is an infinite puzzle game that progressively challenges the brain to train Focus, Attention, Multitasking, Visualization, and Balance. Compete worldwide and view your ranking against everyone else."

You can get the game for free on Android phones right here.
