What is Buy a Slice of Pi™?

There are more than 8 billion people on this planet. At most 1000 will own a slice of π. Will you be one of them?

Buy a Slice of Pi™ is a digital marketplace where you can realize this dream: owning a contiguous run of digits from the first 1,000 digits of π (pi).

Each digit has a unique price based on its position — the earlier a digit sits, the rarer and more valuable it is. Once you purchase a slice, those digits are yours. You can customize your owner page with a bio, links, a profile photo, and even list your slice for resale, potentially earning a profit!

This website is for those who love mathematics, love π, seek a unique social media site, and/or just want to make a quick investment to eventually earn a profit. The supply is limited, so value might increase over time. Buy now, sell part or all of your investment later.

How it works

  1. Browse the digit grid on the home page.
  2. Click and drag to select a contiguous block of digits that are all in the same state (for sale or for sale by owner).
  3. Review the price and click through to purchase.
  4. After buying, personalize your owner page — add a bio, links, and a photo.
