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.
