101 digits of pi will flash before your eyes. (This will take about 30 seconds.) When that is done you can press 1 or 2. If you press 1, you will have 5 minutes to remember as many digits as you can. If you press 2, you are timed to see how long it takes you to type the first 101 digits of pi in order.
