Operation of the game is almost intuitive, and
you can make up your own rules. Each numeric
point value on either game board is a hyperlink
which reveals a question. Advancing the game one
slide past the question (by clicking the screen)
displays the answer. Back on the answer slide
returns you to the game board. SFJ stands for
semi-final jepperdee and FJ means final
jepperdee proceed by clicking screen until you
see the next hyperlink. There is one daily
double on each board click on Heres the
question. For most fun, appropriate hardware
(lights, push-buttons, sounder, lockout
circuitry) should be used. A diagram is
available from the author.
