About
What it is
TempusGuessr is a site of daily games about time. In Timeline, you put events, births and inventions in order; in the Gazette, you guess the year of the news (from 1800 to today); in Brazil Receipt and US Receipt, you guess how much things cost each year (in Brazil since the Real Plan in 1994, in the US since 1980).
How it works
One new challenge per game, every day, worth up to 500 points. The closer you get, the more points. At the end you see your rank for the day and can challenge friends.
Where the data comes from
Every price and event has a cited source (Central Bank of Brazil, U.S. Bureau of Labor Statistics, FIPE, The Economist, Wikidata and others). Items from future challenges only appear on the reference pages after they have been played.
