How to play

Five things are already in order, lowest to highest. Your job is to work out what they're sorted by.

1. 1 Mercury
2. 2 Mars
3. 3 Earth

…sorted by diameter, smallest first.

• Pick one of five options and lock it in.
• Wrong picks are struck out. Keep going until you get it; fewer tries is better.
• Then see the real values, and how the other options would have ordered them.
