About BingoStamp

What is BingoStamp?

BingoStamp is a free, browser-based tool for creating and sharing custom Bingo cards. Whether you're running a team-building activity, a classroom review game, a long road trip, or a bridal shower, you can design a card in under a minute and send it to your group with a single link.

No account. No installs. No paywall. If your phone or laptop has a browser, you're ready to play.

The "no account" philosophy

Most Bingo apps ask you to sign up before you can even see what they do. We think that's backwards. Bingo is a five-minute icebreaker, not a three-year subscription.

Every card you create on BingoStamp is encoded directly into the URL. When you share a link, you're sharing the entire card — squares, win patterns, theme, the lot. There's no server that stores your card, because there's no need for one. That means your cards outlive us; if BingoStamp disappeared tomorrow, anyone with a saved link would still have a working card.

How a card becomes a URL

When you design a card, BingoStamp serialises the full data — title, grid size, list of squares, chosen theme, win patterns — into a compact JSON object. That JSON is compressed and base64-URL-encoded so it's safe to put in an address bar, then appended to bingostamp.com/play/.

The result is a single link you can paste into any chat. When someone opens it, your card is reconstructed locally in their browser. No database lookup, no API request, no loading state.

Who it's for

• Remote teams running meeting bingo, retro bingo, or all-hands bingo
• Teachers building vocabulary, math, or ESL review games
• Families keeping kids entertained on road trips and flights
• Party hosts running bridal showers, baby showers, office holiday parties
• Streamers and communities running movie-night, sports-night, or trivia bingo
• Anyone who has ever thought "wouldn't it be funny if we made bingo for this"

What's next

We're slowly adding more templates, more themes, and more win patterns. Features that are on the table but not committed: multiplayer synced caller mode, printable PDF export, image squares, and a proper library of community-submitted templates.
