  4. 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 (perhaps after the “Daily Double” banner). Advancing the game one slide past a question (by clicking the screen) displays its answer. Clicking “back” on the answer slide returns you to the game board. “FJ” means “final jepperdee;” “SFJ” means “semi-final jepperdee.” There is one daily double on each board; click on “Daily” or “Double” to access the question. You should know this slide show’s details thoroughly before showing it to an audience. For most fun, appropriate hardware (lights, push-buttons, sounder, lockout circuitry) should be used. A conceptual diagram appears on the next slide.
