This is a little game that I found earlier on 9gag.
It is fairly hard and requires you to have some prior knowledge, but finding the shortest way can be very rewarding.
Step 1 : go to wikipedia.org
Step 2 : select ''english'' as language
step 3 : select ''random article'' on the left
step 4 : try getting to the ''Adolf Hitler'' article in as few link presses as possible
step 5 : post your results here.
Here are my 2 examples:
Puerto Rico Highway 38-->Puerto Rico-->Synagog--->Holocaust Theory-->Adolf Hitler
Coeliopsidinae (a type of plant)-->Petals-->Charles Darwing-->Eugenetics-->Adolf Hitler
Edit : If you want to make it a bit harder for yourself, try not going through any country or WW I/WW II
Post your results here
