What the rarity tiers mean

Plankton
The names everyone says first. Safe, but in a rare-answer game they barely score. 100K+ searches a month
Too Clever
Feels like a clever pick, but plenty of other players will think of it too. 10K–100K a month
Schooler
Real names many people know but few would say first. 1K–10K a month
Rare
Recognizable to enthusiasts; a strong pick in rare-answer games. 100–1K a month
Deep Cut
Correct and checkable, but only specialists reach for them. 10–99 a month
One in a Krillion
So rarely searched that Google reports almost nothing. Make sure you can explain it. Under 10 a month
