How to play

Every day there are five things to price. Each one comes from a different range, so every set runs from fractions of a cent to the price of a car or more:

Type a price in US dollars, or drag the slider. The slider moves by powers of ten, so a penny and a Porsche are both one drag away. You can type shorthand like 45k or 1.2m.

Everyone gets the same five items on the same day, and a new set arrives at midnight in your time zone.

Scoring

You score by how close you are in ratio, not in dollars. Missing a pea by double hurts exactly as much as missing a sports car by double.

Five items make a maximum of 500 points a day.

Where the prices come from

Prices are typical US prices from 2024 to 2026, rounded. Each item shows its basis after you guess:

Real prices vary by store, state and season. If you think a price is wrong, tell us and we’ll check it.

Questions

Can I play past days?

Yes. The calendar button lists the last 30 days. Past days count in your stats but don’t extend your streak.

How does “How everyone did” work?

When you finish, your five guesses and score are saved without your name, so you can see where you rank. Until enough people have played a day, the comparison includes clearly labeled starter players.

Do I need an account?

No. Your stats live in your browser.
