Your best cards deserve the spotlight. Showcase your trading cards, build your Vault, and join collectors in crowning the next Grail of the Week.
Grailboard is a collector showcase and community built around the cards you actually own. Build your vault, curate display walls, choose your Holy Grail, and join the weekly vote.
THE WEEKLY GRAIL
Every week, collectors nominate their grails and the community votes. One card is crowned Grail of the Week and takes the spotlight in the app. Cast your vote, rally support for your card, and discover the favorites collectors are talking about.
YOUR VAULT
• Upload up to 100 cards with photos, grading details, and tags
• Arrange cards across up to 3 display walls
• Choose one Holy Grail to represent your collection
• Frame your grail photo exactly how you want it displayed
THE COMMUNITY

• Like and comment on cards
• Browse sports cards, trading card games, and other collectibles
• Receive notifications about nominations, voting, and weekly winners
A FOCUSED COLLECTION
A vault is defined by what you choose to display: up to 100 cards, 3 walls, and 1 Holy Grail.
