A friend of mine gave me this idea...
Someone gives a start and end page on Wikipedia, and the player has to get from one to the other. BUT they can only click on links in the body of the article, and they cannot go back if they don't like the choice they made. The player posts the progression of pages they went through, and then a new challenge.
Example..
Go from
Microsoft:
Microsoft - Wikipedia, the free encyclopedia
to
Brick:
Brick - Wikipedia, the free encyclopedia
How I got there:
Microsoft > Windows > Windows (disambiguation) > Window > Roof > Building > Building material > Brick
Here goes
Go from
Richard III of England: Richard III of England - Wikipedia, the free encyclopedia
To
Southern Cone: Southern Cone - Wikipedia, the free encyclopedia
