Guess Pi Digits Game

How many digits of pi do you know? In this memory game you need to know not only the digits but also where each one falls.

In the basic game, pick a level to set how far into pi the questions go, from the first 10 digits up to the first 1,000. Counting starts at the 3, so in 3.14159 the 3 is the 1st digit, the 1 is the 2nd and the 4 is the 3rd. Asked for the 15th digit, you would answer 9. An answer counts as soon as you press a key, and you score one point for each correct digit.

In the extended game, you see a run of 10, 20 or 30 digits from somewhere in pi. Work out where you are, then type the digits that come next. Pick a range to keep the run inside the part of pi you know, from the first 100 decimal places up to the first 70,000.
