How the game works

Most rounds start with a world map. Drop a pin where you think the product was invented. Then guess its original launch price. We reveal the real price, its value in today’s money and how far off your pin was. The closer you are, the more points you score.

Want the same questions as everyone else? The daily challenge gives you 10 rounds from all categories. It is the one that counts for the leaderboard.
