Invisiclues
The Hitchhiker's Guide to the Galaxy

How to use this booklet
If you are stuck at some point in The Hitchhiker's Guide to the Galaxy, find the question that most pertains to your problem. Uncap the marker and run it once over the first hint. The writing will appear within a second or two. If you are still stumped, go on to the next hint. (Remember to recap the marker when you are done to prevent it from drying out. And by the way, these books are not immortal. InvisiClues you've developed will start to fade after six months.)
(Editor's Note: In other words, click or tap on any invisible clue to magically reveal that clue.)
For example:
How can I tell the difference between a Vogon and a pile of Fronurbdi Fire Fungus?
- You need a Fire Fungus meter.
- You don't have a Fire Fungus meter.
- So you can't. Remind me never to send you to the store for Fronurbdi Fire Fungus.
Your marker contains more than enough fluid to develop the entire booklet. However, if your marker gets lost or dried out, you can order a replacement marker for a nominal fee.
Once you have finished The Hitchhiker's Guide to the Galaxy, try the things in the "For Your Amusement" section. Don't look at them before you've finished, though -- they may reveal answers to certain problems.
