Rankle #1 answer: city population (fewest to most)

The answer

Rank by city population (fewest to most)

1. 1Oslo709K
2. 2Rome2.87M
3. 3London9.09M
4. 4Tokyo13.96M

Why this order

Ranked fewest to most, Oslo (709K) goes at the top and Tokyo (13.96M) at the bottom.

The closest call is London (9.09M) against Tokyo (13.96M), about 54% apart. That is the swap most likely to cost a point.

The biggest gap is between Oslo and Rome, about 4 times apart, so that boundary should be the easiest part of the order to get right.

From top to bottom the figures span a factor of roughly 20.

These are the figures the game reveals after you submit. They are rounded; only the order is scored.

Difficulty: medium, judged by how close the tightest pair is.
