The digits of pi in a spiral in the OutClocked halving block

Pi Day trivia

Seven questions.
Easy as pie.

Every March 14 (3/14), OutClocked's daily game turns into seven questions about pi: the number, its history and the circles it measures. Everyone plays the same game. Bring a calculator if you like, but the clock won't wait for it.

How it works

You get 60 seconds for the first question, and the clock halves after every one, down to under a second for the seventh. One wrong answer or one missed clock and you're done. A new game comes out every day at 6am Eastern, with a themed one on holidays. More in the FAQ.
