More accessible quantum games: Quantum Minigolf http://quantumminigolf.sourceforge.net/ and Quantum Tic-tac-toe http://cel.edu/Quantum/Tic-Tac-Toe/ (which seems to require Java - anyone know of a better version?)

Edit: looks like there's an Android version https://play.google.com/store/apps/details?id=com.gmail.sman... and iPhone https://itunes.apple.com/us/app/quantum-tic-tac-toe-lite/id3...
