## What is Trendline?

Every day, Trendline shows you something real (how the price of oil moved, how a country's population grew, how many people named Karen there are at each age) and hides the answer. You drag a line across a blank chart to draw what you think happened. Then the real data appears, with one honest score and the story behind it.

DAILY ROUNDS A fresh puzzle in each of five themes, every day: • World: climate, markets, the economy, technology, nature and space • People: population, sport, culture and society • Ages: draw how a group is spread across ages, from people named Jennifer to Olympic skiers to the users of an app, against everyone else • Sunday Special: one line is drawn for you, you draw the other, and the reveal tells you whether the two things are really connected or only look it • Maths: draw the graph of a function like y = x² + 3x + 1 and get it graded like homework, A+ to F−. The level rises through the week, from a straight line on Monday to a proper brain-teaser on Sunday

ONE CLEAR SCORE Your score is the typical distance between your line and the real one, as a share of the chart's height. No hidden formulas: 0% miss is a perfect 100, and every 1% of miss costs 3 points. Small mistakes cost little, big ones add up.

LEARN SOMETHING EACH TIME Every reveal gives you the real numbers, a sentence that puts them in context, and the source they came from. Log-scale charts are explained right in the app.
