Casio Tic-Tac-Toe Game Calculator

Here’s another unusual game calculator by Casio, the MG-777. We determined that one of the games on this one is tic-tac-toe, but aren’t sure of the other two. In addition to calculator functions and game play, this one offers a clock. This model is reminiscient of Parker Bros’ Merlin, that great LED handheld game from the ’70s.
