The answers, by rarity
| Tier | Points | Banked answers |
|---|---|---|
| One in a Noillirk | 100 | Tau neutrino, Muon |
| Deep Cut | 85 | Gluon, Tau lepton |
| Rare | 60 | Positron, Electron neutrino |
| Schooler | 30 | Neutrino, Photon |
| Too Clever | 15 | Quark, Neutron |
| Plankton | 10 | Proton, Electron |
How the crowd plays it
"Proton" is what this prompt harvests from almost everyone — that reliability is what makes rarity measurable. Even "Quark", the connoisseur's decoy, is banked at just 15 points: the mirror has seen it a thousand times.
The deep water of this prompt belongs to answers like "Gluon" (85). Rarer still is "Tau neutrino", the One in a Noillirk gem: find it under a 25-second clock and a single prompt has carried you a full kilometre down.
Playing this prompt backwards
When this question surfaces in a dive, your 25 seconds are best spent in reverse: first, name the Plankton answer silently and let it go; second, refuse the Too Clever answer unless the clock is dying; third, search your second page — the runner-up, the older one, the one from the smaller place. In science, that means remembering that work the problem backwards, the way real science often happens: start from the phenomenon and reverse-engineer the name. The mirror rewards reasoning, not just recall.
