Spend $1 Billion

You have one billion dollars. Here is a shop. Getting rid of it all is much harder than it sounds, which is the entire point.

Money left $1,000,000,000

How to play

  1. Press plus to buy, minus to sell.
  2. Watch your balance at the top.
  3. Try to reach exactly zero. Good luck.

How it works

Every purchase updates a running total using whole-number arithmetic, so the balance never drifts by a cent. Your receipt is built from what you actually bought and can be shared without saving anything.

Why this exists

It is the fastest way to understand that a billion is not just a slightly bigger million.
