Black Box is an abstract board game for one or two players, which simulates shooting rays into a black box to deduce the locations of "atoms" hidden inside. It was created by Eric Solomon. The board game was published by Waddingtons from the mid-1970s and by Parker Brothers in the late 1970s. The game can also be played with pen and paper, and there are numerous computer implementations for many different platforms, including one which can be run from the Emacs text editor.
