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 “Here’s the question.”
For most fun, appropriate hardware (lights, push-buttons,
sounder, lockout circuitry) should be used. A diagram is available from
the author.
