An examination of TIC-TAC-TOE like games
Robert C. Gammill · 1974
There is a class of games which resemble TIC-TAC-TOE. These are games where two players alternately put X's and O's into playing spaces, attempting to get n of their signs in a row. Well-known games of this class are TIC-TAC-TOE (3 X 3) and QUBIC (4 X 4 X 4). The boards of these games form squares, cubes and hypercubes with n playing positions on a side. We will speak of these games as nk TIC-TAC-TOE following Citrenbaum.
