About this pack
This pack works outward from Mercury through the planets everyone learns at school, with hints that give each one's defining fact — closest to the sun, the hottest, the red one, the largest. It doubles as a quick astronomy refresher, and because planet names are short and distinctive, it is one of the faster packs to clear.
Solving tips
• Planet names are four to seven letters. The cipher length alone often identifies the answer.
• The hint is a superlative — hottest, largest, closest. If you know the fact, you know the word.
• Look for doubled letters: several planet names carry them, and they are the quickest foothold.
Common questions
Are the answers shown?
Yes, underneath each puzzle.
Is Pluto included?
The pack sticks to the eight planets, so Pluto sits this one out — though the hints will not hold it against you.
