Released as part of the part of "Leisure Time Classics" game pack. The game is played on a cube 4x4x4. The object is to get a row of 4 O's in any direction, including diagonals. You must stop the machine from getting a row of X's. You'll go first and will be asked for the level, column and row in which you want to play. The levels are marked above the board 1 through 4 and the columns are numbered down the board in the same way. If you enter 0 to all the questions the board is reset. If you make a mistake enter R in answer to "Row"? and you can reenter your play. You must finish a game before you can quit.
