Zone X

Zone X is a graphical version of a game of the same name. In the game the player must find the intersection point of two lines on a grid. The invisible lines will divide the grid in four areas (x, o, + and hatched). The player can give a coordinate and the computer will highlight the coordinate on the grid in the right area coding. The game is over when the player has found the intersection point of the two lines. The fewer guesses the player made the better.
