• Blazor Web Assembly (WASM) / C# / .NET 8.0 / Progressive Web App (PWA)
• PeerJS is used via JSInterop to establish peer-to-peer communication between the game host and the players. No server required!
• The Web Speech API and SpeechSynthesisUtterance (text-to-speech) is used to announce the numbers called on the player instances.
• Platform-native emoji characters are used for stamping the bingo cards.
• Screen Wake Lock API is used to keep the screen from timing out / turning off on devices that have support for it.
• Dynamically updates an inline SVG representing the game pattern by binding values from an array of bits (UInt32).
• GitHub Actions is used to build and publish the Blazor WASM app to GitHub pages.

Play a game at https://jasonmarckel.github.io/BlazorBingo/.

Select 'Host' to start a new Bingo Hall and generate the game code for the session. Enter the game code in the other instances and select 'Join'.

BlazorBingo can be installed/pinned to the homescreen and launched as a full screen PWA web app without the browser's chome around it.

TODO:

• Add special effects for winner (confetti, fireworks, etc.)
• Create an app icon!
• Implement best practice for PWA app to notify that a new version is available and self-update.
  • Currently for an installed/pinned PWA, it must be launched, wait a few seconds, killed, and re-opened for it to detect, install, and use the latest version.
• Add statistics (games played, games won, minutes/hours/days played).
