Measure the reconstruction, not the movie

Long tails, raised necks and different body plans make prehistoric silhouettes difficult to compare at a glance. Start at the marked endpoints and judge the selected reconstruction against its reference.

Body length follows the dimension named by the entry. Do not substitute shoulder height, mass or the visible height of a posed skeleton for a head-to-tail measurement.

Make a measurement, then test it

  1. 01 · Read the reference

    Find the fixed silhouette and read its number, unit and measurement direction. Decide which endpoints you are comparing before changing the target.

  2. 02 · Adjust the target

    Drag the target or use the ruler controls. A two-finger pinch changes your guess on touchscreens; the zoom buttons change the view. You can also use the plus and minus buttons for smaller adjustments.

  3. 03 · Reveal and compare

    Submit once you are satisfied. The reveal shows the recorded size beside your estimate. Base points depend on the size ratio; round weights turn those points into the run total.

What the label changes

Fossil reconstructions are estimates. The puzzle uses a particular stored size so that a round can be scored consistently; it does not resolve scientific uncertainty about every specimen.

A useful way to practise

Separate the torso from the tail in your first estimate, then compare their combined span with the reference. Review the species and measurement note when a reconstruction looks unfamiliar.

Inspect the objects behind a round

The library lets you search names, filter a theme and inspect measurement notes and source credits. Retired entries remain available to explain older games, but are excluded from new draws. Counts there follow the current catalogue rather than a fixed list in this guide.

Choose your next set

Daily offers five rounds for the selected category and date. Unlimited lets you choose 5, 10, 20 or an endless run; these results are separate from Daily. An endless run can be finished after at least five rounds.

How to play Sizekin

  1. Compare. Read the dark reference first: its label tells you the known size and which dimension is measured.
  2. Resize. Resize the light shape with a swipe, its handle, the ruler or the arrow keys. On touchscreens, pinching changes your guess. The zoom buttons only change the view.
  3. Lock in. Submit when the proportions look right. Red shows the selected true size. Each round starts with a score out of 100: within 6% earns 100, double or half earns 45, and a fivefold error earns 0.
