Extraplot

Extraplot is a daily chart puzzle where your mission is to draw how a real line continues after it stops at a cut-off year.

Each puzzle shows a real chart on a surprising topic, from baby names to search fads. The line runs up to a dashed cut-off, and the rest is hidden. Your job is to sketch where you think the data went next, then see how close you got.

• Drag across the shaded side of the chart to draw your prediction.
• Reveal the real line, which appears right over your drawing.
• The smaller the gap between the two, the more points you score.
• Every round ends with a reveal, so you always see what really happened.

Why we like it:

• ✅Every chart is a small story, and guessing the twist is half the fun.
• ✅Drawing your answer feels far more personal than picking from a list.
• ✅You come away knowing a little more about how trends rise, crash, and rebound.

Hint: Look at the shape of the line before the cut-off, but don't assume it keeps going the same way. Ask what real-world event could bend the trend, like a boom, a crash, or a sudden fad.
