Before you go, we thought you'd like these...

Ah, pi day. The "holiday" paying homage to the mathematical constant has arrived once again, and this time around, there's more at stake than ever.

Acknowledging that bliss comes in the form of free pies, Pizza Hut announced that they would be holding a math contest in celebration of all things circular.

Posted on their blog, the fast-food chain teamed up with John H. Conway, an English mathematician, to create three challenging, original math questions. For the participants who are brave enough to take a stab at the problems, they will also have to beat out the other wiz kids to walk away with the prize.

Clarified in the rules, the chain asks fans to, "Take a look at the math problems below and provide your answer to Option A, B, or C in the comments section. Please be sure to note which you are trying to solve. Answers will be time stamped to determine the potential winner and participants can only win once."

OPTION A:

I'm thinking of a ten-digit integer whose digits are all distinct. It happens that the number formed by the first n of them is divisible by n for each n from 1 to 10. What is my number?

OPTION B:

Our school's puzzle-club meets in one of the schoolrooms every Friday after school.

Last Friday, one of the members said, "I've hidden a list of numbers in this envelope that add up to the number of this room." A girl said, "That's obviously not enough information to determine the number of the room. If you told us the number of numbers in the envelope and their product, would that be enough to work them all out?"

He (after scribbling for some time): "No." She (after scribbling for some more time): "well, at least I've worked out their product."

What is the number of the school room we meet in?"

OPTION C:

My key-rings are metal circles of diameter about two inches. They are all linked together in a strange jumble, so that try as I might, I can't tell any pair from any other pair.

However, I can tell some triple from other triples, even though I've never been able to distinguish left from right. What are the possible numbers of key-rings in this jumble?

So, what does the grand-prize winner walk away with? 3.14 YEARS worth of free pizza awarded in the form of Pizza Hut gift cards. That's 1,147 days worth, in case you were wondering.

In response to the complexity of the problems, people have been taking to Twitter to express their frustrations stemming from their lack of math skills, which, sadly means no free pizza in their near future.
