Why kids like it
The line starts with every number labelled and slowly becomes a blank ruler, so guessing where a number lives feels like a real puzzle.
Read a number and drag the marker to where it belongs on the line. Early levels label every tick; later levels hide them until only the two ends remain, so children estimate magnitude instead of counting.
