The InvisiClues provide everything you need to crack the toughest puzzles Infocom has to offer. The hints are amusingly and cunningly written to subtly provide solutions without giving answers away. Furthermore, Infocom didn't want the questions themselves to give too much away. If every InvisiClue question were pertinent to the game, the questions themselves would give far too much away. To counteract this, some topics contain random nonsense questions (i.e. questions that have nothing to do with the game). Therefore, do not use the presence or absence of a question on a certain topic as an indication of what is important, and don't assume that long answers indicate important questions.
Unlike the plain-text versions of the InvisiClues, the hypertext versions contained in these pages are an attempt to "protect" readers from accidentally reading answers. Readers can jump to appropriate topics from the table of contents. At the top of each section is a list of the questions for that topic. Each of these is a link to the answers. Each of the answers has a graphic bar separating them (the best way I could think of to provide some cross-question spoiler "protection").
The InvisiClues contained in these homepages were derived from the text versions by Paul David Doherty, Peter Doherty, Graeme Cree, Thomas Schaefer, and Judy Lynch. Additional hints come from The Lost Treasures of Infocom I hintbook and online hints from those games that have them.
Some of the InvisiClue pages may contain typos or formatting errors. This is due to the fact that I did not "webbify" the pages by hand and I didn't proofread the pages for the games that I have completed (afterall, I don't want to have any game spoiled either). If you find a significant error you can email me at email@example.com.
Finally, a word of warning. The answers to all of the major problems of each of the games can be found in the InvisiClues. However, if you want to solve the problems yourself and do not want the game "ruined" then do not read the hints.
