Guessing GameCode Wizard, 12-30-2006 |
This uses a form and random numbers to play a numerical guessing game - based on the card game 'war'.
The user sets the points to play for, and the computer player guesses a number, and the computer sets
the true number. Whoever is closest wins the points. It only requires this file plus two images, one named
red.jpg and one named blue.jpg so the graph showing who is winning works. It could easily be rewritten to have
a character in place of the images, if you like.
