TicTacToe is an old Java 1.1 AWT (GUI) applet to play the child's game of Tic-Tac-Toe, also known as Ticktacktoe, X's and O's, Naughts and Crosses. Click the mouse on a position of your choice. You are the magenta X's and you move first. The computer has the blue O's. To win, you must have a complete horizontal line, a complete vertical line, or a complete diagonal line. There can be several diagonals. Winning lines are shown in red. For instructions on how best to play the game ... ask a child! The only weird part is that the number of rows and columns can be different.
This applet runs as a single class in the main GUI thread and does not have a delay or any animation before the computer's move appears. Code for that can be copied from the Dots and Boxes game or the Reversi game.
The program's comments and documentation reference web sites that no longer exist, and discuss differences in Java versions that are now meaningless. No changes will be considered. Web page applets are obsolete and may run as stand-alone applications with the help of a wrapper (included). This becomes less likely after Java 9 (2017). Rewriting for Java Swing or newer JavaFX is not an easy job.
