Ballpark

Ballpark is a short estimation game about business. You are shown a well known company with its sector and country, and you have to put three numbers on it: when it was founded, how much it earns in a year and what it is worth. You do not need to be exact. Each guess scores on how close it is, so a good sense of scale counts for more than remembered figures.

The daily game features one company, chosen by the date, so everyone playing that day gets the same one. You drag a slider to your guess for the founding year, lock it in and see the real answer, then do the same for revenue and valuation. Each of the three is worth up to 100 points, and the result can be shared as a short card. Only the daily company counts toward your streak.

The site says its pool holds hundreds of well known American and European companies (the page's own list has 365), with figures taken from public financial data and rounded for fair play. After the daily you can play random companies as often as you like. There is no account or sign-up. It suits people who follow business news, investing or markets and want a quick test of how big companies really are.
