How to play

Guess the hammer price of one car a day.

• One live Bring a Trailer auction, no reserve, so it will sell.
• One sealed guess. No changes after midnight ET.
• Research all you like. The listing is a click away; the comments are the game.
• The hammer falls about a week later. Your score lands in the book.

Examples

Say the car sells for $27,100.

1. $26,0004% low · 94 pts
   Within 5% is a bullseye.
2. $30,40012% high · 84 pts
   Off by 12% still scores well.
3. $54,2002x high · 0 pts
   Double (or half) the hammer scores nothing.

Scoring is by ratio, so a $12k Miata and a $700k Ferrari play the same. Your streak counts days you guessed, not days you were right.

Glossary

Borrowed from the saleroom. Bring a Trailer is a silent countdown; we brought the auctioneer.

Going once

The auctioneer's first call. You commit a number, then wait for the hammer.

Hammer

The final price. Every car here is no reserve, so the hammer always falls.

The book

Where a bidder's commitments are recorded. Your pending and settled guesses.

Paddle number

Your number in the room. It is your handle here; no name needed.

Knocked down

Sold. A guess is scored the moment its car is knocked down.

Fair warning

The last call before the hammer. Here: under an hour until guessing closes.

The crowd

Everyone else's guesses on the same car, shown once the window locks.

Bullseye

Within 5% of the hammer.

Sleeper

A car that blows past what the crowd expected.

White glove

A sale where every lot sells. A perfect week of bullseyes.
