No graph this time, just three numbers. Sculpt a histogram to match a hidden distribution using only its mean, spread and skew.

How to play
You see the target's summary statistics but never its bars. Drag three sliders, mean, spread and skew, to build your own histogram on the canvas. Submit before the timer ends; the closer your shape matches the hidden target, the higher you score. It inverts the usual task: instead of reading a curve into numbers, you turn numbers back into a curve.
Each round gives a fresh hidden target and a 45-second clock.
Your stats are revealed against the target's after you submit.
Score grades how well your shape fits.
Controls
Desktop: drag the mean, spread and skew sliders, then click Submit.
Phone & tablet: drag the sliders and tap Submit, fully touch-friendly.
Game modes
Daily: the same seeded target for everyone.
Practice: a fresh randomized target each round.
Tips & strategy
Set the mean to position the peak first, then widen or narrow with spread.
Push skew toward whichever tail the stats imply is longer.
