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. What rapidly converging formula for calculation of pi was found by Machin in 1706?

2. There was a time (a while ago) when people were trying very hard to 'square the circle.' It was said at the time that it was even an illness and a name was given to it. What is it?

3. Which of the following fractions most closely approximates pi?

4. One way to calculate the value of pi is to find the perimeter of polygons inscribing and circumscribing a circle. The circumference of the circle lies in between those two values, and the values approach pi as the number of sides of the polygon approaches infinity. Who originated this method of pi approximation?

5. What is the formal definition of pi?
