How it works
Everyone sees the same five sales in the same order on a given UTC day. You get up to 1,000 points per card. Points = 1,000 × max(0, 1 − |guess − actual price| / actual price), rounded to the nearest whole point. A perfect guess earns 1,000 points; 10% off earns 900; 50% off earns 500; 100% or more off earns 0. Over and under guesses are treated equally. Five cards total a maximum of 5,000 points. Results include the sale date, venue and an original venue archive link (lot number supplied where available).
One scored attempt per UTC day is stored on your device. Practice and archived games do not affect it. Clearing browser storage or changing devices bypasses this restriction.
The live game uses imported eBay sold listings with dates, prices and matching listing image URLs. Records with uncertain prices, missing dates or missing photos are excluded. Image availability and reuse rights depend on the provider and marketplace. Fanatics and Goldin importers are not yet enabled.
DATA TRANSPARENCY: The current basketball, football and baseball set contains — documented transactions. Sale figures come from venue archives or official venue announcements; some links open an archive listing rather than an individual lot. No automatic ingestion, new-sale guarantee, or worldwide leaderboard is claimed.
