A game where you randomly pick one of the people you follow then you start randomly clicking on photos in the "Following" section on the right side of the page. Every time you pull up a new profile you randomly click again on one the of the photos under the "Following" section. You keep clicking until you accomplish one of the following:
You find yourself again after at least 5 clicks +5 (points)
You find someone you know personally +2
You travel to a foreign country +1 for each new country
You travel back to your own country +1
You find someone from your state +1
You find someone famous +1
You find someone with no followers -10 (and game over)
Everyone can make up their own rules and scoring. It's a great alternative to solitaire and you can run into some really interesting people to follow.
I played a few rounds of Twitter Roulette while I waited for my laundry to dry. I found a really cool guy to follow in France and I lost the first round after I clicked on some lady in Germany with over 10,000 followers but she didn't follow anyone.
