1. You're a student, right, and this is a homework assignment, correct? If so, it should be posted in the "Homework" section of this board.
2. Just so you understand, we're not here to do your homework for you. If you need help with homework, people will be happy to assist you. But you need to show us that you have at least some understanding of the assignment, and that you've already made an effort to get answers to your questions.
3. You should be able to give us specific questions that you need answers to. Don't come here and just dump "Please tell me how to do this!" in our laps.
[What you posted looks like an incomplete schematic that you're supposed to fill in for your assignment.] [Edit] On closer examination, it actually looks like a complete schematic, assuming the input is completely manual (players flipping switches).
