Estimate 1D
No options at all — place your pin on a number line. Scored by how close you get, so a good instinct is worth points even without the exact figure.
What makes it hard
The range offered is wide enough that the midpoint is not a safe guess. Knowing the order of magnitude is worth real points; knowing the figure is worth all of them.

What the clues give you
Instead of text, this type carries a pool of five numeric anchors. The first two tiers reveal one each; the third shades out a region of the axis, telling you where the answer is not.
