Where the cards come from

Every picture is a scan or photo of a card in the owner's own collection: no seller photos, no listing photos and no grading company's images.

How the answers are known

Most cards are raw scans from the owner's own collection, front and back, at full scanner resolution. Scored cards are photos of the graded card in its slab, cropped inside the slab so the label never shows.

• Most cards have never been graded. Those rounds aren't scored: there is no grade to score against. Once 100 players have called a card, its reveal shows how players called it.
• A scored card has been graded by a grading company, and the answer is the grade it returned. Its label is cropped out of the picture.
• Some study cards are at the grader now. A study card with no grade yet is pending: your call is saved and scores once its grade comes back.
• Points are measured against the typical grade: the middle grade of every scored card, a call anyone could make without looking. It scores 0, like Not sure. Each half grade your call lands closer to the real grade than the typical grade does earns a point, and each half grade further costs one, up to 3 either way. An exact call also earns a bonus.
