This screencast shows how to play the Textravex logic puzzles that are come with Ubuntu Linux. I've played these fun puzzles with kids as young as kindergarten and seniors in their late 80's. These puzzles are particularly fun to play socially, where two people discuss the next possible moves.
You can use Ubuntu Linux on recent Macs and Windows computers using the free Virtualbox software. http://www.virtualbox.org
