Publisher's blurb Tic-Tac-Toe, four in a row? That's only one of the differences with Quad, Acorn's challenging three dimensional game. A graphically represented cube, four rows by four columns by four levels. Quad gives you 64 different playing positions for your X's and O's, and 76 different winning four-in-a-row combinations. Play Quad against your computer or a friend: against the computer, there are four levels of difficulty available. You can rotate the cube six different ways to get a new perspective (or confuse your opponent!). For even more challenge, set the built-in game clock - it'll forfeit your move if time runs out!
