Finally this is your chance to pay tribute to the magnificent transcendental number that we have all grown to love! Here are 25 questions (given to you 5 at a time), picked randomly from my pi question database. Get ready for the thrill of your lifetime, the ultimate challenge, The Pi Trivia Game!

1. The following are all mnemonics for remembering the first few digits of pi (the number of letters in each word corresponds to a digit of pi). Which of these was written in 1995 by Michael Keith?

2. In 1897 a state House of Representatives unanimously passed a bill setting pi equal to 16/(sqrt 3), which approximately equals 9.2376. In which state of the United States did this occur?

3. Consider the following series of natural numbers, constructed by taking successively larger strings of digits from the beginning of the decimal expansion of the number pi:
3, 31, 314, 3141, 31415, 314159, 3141592, etc.
Out of the first 1000 numbers in this series, how many are primes? (for example, the first two numbers, 3 and 31, are both primes)

4. One of the best-known series representations of pi is the Gregory-Liebniz formula, which is:
