關於井字遊戲
Tic-Tac-Toe, also called noughts and crosses, is one of the oldest pencil-and-paper games in the world. In this Vozu version you play X against a computer opponent that plays O, on the familiar 3-by-3 grid.
Be warned: the computer looks ahead at every possible game and never makes a mistake. That turns a simple pencil-and-paper game into a neat little challenge. Can you play well enough to hold a perfect opponent to a draw, round after round? A running tally of your wins, draws and the computer's wins keeps score for the whole session.
玩法
- You are X and you always move first. Tap or click an empty square to place your mark.
- The computer answers immediately with an O.
- Get three of your marks in a row, across, down or diagonally, to win the round.
- If all nine squares fill up with no line of three, the round is a draw.
- Press New Round to play again. The scoreboard under the grid keeps counting.

小技巧
- Open in a corner or the center. An edge opening gives you fewer lines to work with.
- Always check for the computer's two-in-a-row before you do anything else, and block it.
- If you open in a corner and the computer takes the center, take the opposite corner to stay safe.
- A draw against this opponent is a good result. One careless move and it will take the win.
- Treat every round as practice in thinking one move ahead: before you place an X, picture the computer's best reply.
