The listing, Lightdog Full Game of CLUE on CD-ROM has ended.
*No manual I have included screen shots of what shows up on my Mac computer. However, I cannot install this on my version. I think it is for an older PC. Below is the info I found out about it on the Internet....
According to the Internet this is what is on this CD: The General Mills CD-ROM computer game cereal promotion was among the more controversial electronic issues during the summer of 2000. In late July, cereal boxes began appearing on grocery store shelves containing one of five popular games: Amazon Trail 3rd Edition, Carmen Sandiego Word Detective, Clue, LEGO Creator, and Who Wants to be a Millionaire. As was advertised on the box, each CD also contained additional software, including a Merriam-Webster Dictionary and an offer from the Internet service provider Lightdog.
The first four titles also contained a non-advertised copy of Zondervan Publishing House's New International Version of the Holy Bible. The inclusion of the bible was not noted on the cereal box, nor on the disc sleeve, nor on the surface of the CD-ROM itself. Moreover, when the user began to explore the additional software included on the disc, an otherwise uninformative "NIV" icon appeared on the list of available options, still with no indication that a copy of the Bible was included. Only by clicking on the "NIV" icon, and beginning installation of the Bible software, did the user learn what was being installed. Yet even this was not the end of the process. After installation, users were encouraged to register their new digital copies of the Bible to receive free "Inspirational Readings," plus a five dollar rebate on the purchase of other Zondervan products.

I don't have any more info. on it. So if you're not sure if it will work on your computer then don't bid. The disk does not say for PC or for Mac - so I do not know either.
