How to play this prompt
Strategy notes specific to “Name a vitamin” — not generic advice.
Most players know the famous examples. The depth is in the specific names, elements, and phenomena beyond the textbook highlights.
The winning instinct on this one: skip your first thought entirely and type your second. Biotin is a perfect example — completely valid, just not the reflex answer. Niacin plays the same role as a backup.
Vitamin C feels safe because it's obviously right. That's precisely why it's worth the least — safety is crowded. Vitamin A is the same kind of comfortable, low-scoring pick.
Notice how Thiamine (Rare) outscores Vitamin C (Plankton) without being obscure at all. Rarity isn't about difficulty — it's about what the crowd overlooks.
Build yourself a mental shelf for this prompt: Riboflavin, Pantothenic acid, Niacin. They're different answers, same rarity neighborhood — and that neighborhood is where dives are won.
Rated 4/5 difficulty — only 12 banked answers, so matching the bank is genuinely hard. Precision matters more than speed here.
