Music Bingo Application

A hosted music bingo game built to run a venue entertainment night from one screen, without a laptop full of spreadsheets.

The business problem

What was going wrong

Running a music bingo night manually means printed cards, a spreadsheet of tracks, a separate list of what has already played, and a host trying to verify a winning card in front of a room. Every part of it is a place to lose your place.

The solution

What we proposed

A single application that generates the cards, tracks what has played, and verifies a claimed win against the actual play history. Built as an internal Mulate product first, so the operational rough edges get found by us rather than by a venue in front of a crowd.

Key functionality

What it does.

  • Card generation from a configured track list
  • Play history tracking during a round
  • Win verification against what has actually been played
  • Host screen designed to be read across a room
  • Round and game state that survives a page refresh

Technology

What it is built on

  • Next.js App Router
  • TypeScript
  • Tailwind CSS

Process

How it ran

    Built card generation, play tracking and verification.

  4. 04

    Tested against live rounds.

We build our own products too.

Internal products are where we prove an idea before we recommend it to a client.
