About Gemmed
Gemmed is a daily price guide game for card collectors. Every day each section (Pokémon, Basketball, Baseball, Football, Soccer and Magic) shows one graded card in its slab. You get six guesses at what that slab sold for. A guess within 5% wins, and each miss tells you higher or lower. A new slab arrives at midnight Eastern.
Gemmed is made by Invested Inc.
Where the slabs come from
Every puzzle is one real, recorded sale of one physical slab at auction. Each answer names where it sold and links to the listing. We cover the certification number on each slab, so the answer can't be looked up mid-game.
Questions
Is the answer what the card is worth?
No. It is what this particular slab sold for, at one venue on one date, as the venue reported it. The same card can sell for very different prices. Gemmed is a game, not an appraisal or financial advice.
Why does the archive need my email?
Today's slabs are free for everyone. Your email opens the archive of past slabs and unlocks your streak and stats, with no password. If you play on another device, enter the same email there. See Privacy for what we do with it.
Do archive games count?
They don't count toward that day's player stats or your streak. Only games finished on their own day do.
I found a mistake.
