Custom bingo cards, made absurd

Build any-size bingo cards from your own text, share them by URL, and play with friends — no accounts, no backend, no data leaving the browser. Just over-the-top stamp animations and good old shouty BINGO.

Features

Build any card

3×3 to 7×7 grids, free space, item-pool randomisation, drag-to-reorder, and a live preview as you type.

Share by URL

The whole card definition is compressed into the URL fragment. No server, no database, no signup — just send a link.

Over-the-top reactions

Confetti, fireworks, stamp animations, and screen-shake on BINGO. Built for parties, weddings, and meetings that should be more fun.

QR codes, instantly

Generate a downloadable QR for any card. Hand out cards in person without anyone typing a URL.

Themes & sounds

Multiple themes, dark mode, custom palettes, plus an optional audio layer for the full party effect.

Offline-first

Marks, achievements, and your created cards live in your browser. Works on flights and patchy venue wifi.
