How to play Call the Grade

What is Call the Grade?

A daily game for collectors who like to call a card's grade before the slab does. Every scan is of a card in the owner's own collection.

How does a day work?

1. Zoom in on the corners, edges and surface. Flip it to check the back.
2. Call a grade from 10 down to 1, or tap Not sure. Not sure never costs a thing.
3. Slabbed cards score. Raw ones go on the board of collector calls, and cards at the grader score when they come back.

5 rounds a day, the same for every player. There is no clock: take as long as you like. A new day starts at midnight, your local time.

How do points work?

A scored card earns a point for each half grade your call lands closer than the typical grade (the middle grade of the scored cards), and costs one for each half grade further, up to 3 either way. Most cards aren't scored: they show how other players called them. Nothing is scored for speed or for agreeing with other players.

What if the answer isn't in yet?

Your call is saved. When the answer comes in, it is scored and your day's result updates the next time you visit.

How do challenges work?

After your day, tap Challenge to share a link. Your friend plays the same rounds, and your calls stay hidden until they finish.

When can I see past answers?

Two days after a round was played, once its day has passed everywhere, for every card whose answer is known.
