How To Play
The game is similar to the traditional game of tic-tac-toe, but is played on four 4 × 4 grids stacked vertically on top of each other. To win, a player must place four of their symbol on four squares that line up vertically, horizontally, or diagonally, on a single grid, or spaced evenly over all four grids.
You can play against the computer or against another player (local or over a network). It is also possible to let two computer enemies play against each other. These computer enemies can be loaded from external Java Archives (JAR files), only one (very hard to beat) computer enemy is built in.
