Serious ‘XM (aka W2XM) presents

1. Serious ‘XM(aka W2XM)presents Exam-Prep Jepperdee: General-Class Edition

2. 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 a question (by clicking the screen) displays its answer. Clicking “Back” on the answer slide returns you to the game board. “SFJ” stands for “semi-final jepperdee” and “FJ” means “final jepperdee.” There is one daily double on each board; click on “Here’s the question.” The game host 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 diagram appears on the last slide.
