Smallest to Biggest

Arrange copies of one object by their visible sizes. Compare neighbours on a common baseline, then explore a clearly labelled reverse order and missing middle.

How to play

Select an object and use Move left or Move right, or drag it to another position. Check explains one pair to compare. Later rows say Biggest to smallest or ask for a missing middle size. Objects keep the same scale when the row scrolls.

For Smallest to biggest, a smaller object belongs before a bigger neighbour. For Biggest to smallest, turn that rule around. In a middle-size puzzle, compare both fixed neighbours. Undo, Reset and a little hint are nearby.
