Guess the eCPM
Ten bid requests. For each one, guess the clearing price. Within 10% scores 100, within 20% scores 60, within 35% scores 25 — and streaks multiply. After each guess you see exactly which signal moved the price.

Price anatomy — how the exchange sees it
Base — a plain 30-second audio slot clears around $3.20.
Format — mid-roll ×1.35, podcast 60s ×1.5, post-roll ×0.7.
Enrichment — genre, geo and segments together add 40–75%. A raw request loses 15–45%.
Supply chain — missing schain halves the price. Many buyers won't bid at all.
IVT risk — high risk means the value is near zero regardless of everything else.
