Setup Instructions

How to Play

• From the home page (index.html) the presenter creates two Teams. For example. Team A and Team B.

• Upon submitting these teams a new "Game" is created.

• The presenter then instructions players to visit play.html. They will see two buttons, one for Team A and one for Team B.

  • Note; in the image below the url is specifically to my personal demo of the game. You will need to replace that url with your own when deploying

• The goal is to have 1/2 the room hit one button and the other half the second button as fast as they can.

• Each button press is logged and displayed in real time on the home page. When one team gets far enough ahead of the other team the Functions logo will move and eventually show a winner!

How does it work?

Behind the scenes we are using Azure Functions with Storage Queues, Table Storage and Proxies.
