About Price Time Machine

This page is all about Price Time Machine, a free daily game about historical prices and the stories behind famous products. How much did the first Barbie cost? Where was the Rubik’s Cube invented? What would a 1960s house cost in today’s money? We turn questions like these into a quick daily quiz you can play in a few minutes.

Why we made it

A price from the past is only half the story. Put it next to what it would cost today and you suddenly see how expensive a 1980s computer really was, or how a 1950s chocolate bar compares with one today. Price Time Machine is built around that “then and now” moment, with a world map so you learn where things came from too.

If you enjoy retro price quizzes, Price Is Right-style guessing games or a good dose of nostalgia, this is for you.

Where our prices come from

Every product is a real question with a real launch price. We research each one from sources from the time, such as original adverts, catalogues, press releases and news reports. Then we check every question by hand before we publish it.

We show prices in US dollars, as the product first sold in the United States. We adjust them for inflation with the US Consumer Price Index (CPI-U) from the US Bureau of Labor Statistics. How to play explains how today’s prices and scores are worked out.

Spotted a price or a place that looks wrong? Please tell us and we’ll check it.

What’s in the game

Every day there’s a new daily challenge with the same 10 questions for everyone, and a leaderboard with daily, weekly and all-time rankings.
