It's a tool for running an online raffle. When my local folk club went virtual in March 2020, we wanted to try and keep as much of the actual folk club as we could but we couldn't find a simple way to generate a random number to pick the winner, so I wrote this. To use it for a raffle, allocate each person a number then press the "Who's won?" button. No doubt you could use it for other things too.
You can set the raffulator up for your needs by pressing the little spanner and screwdriver icon.
You can set the title that appears at the top of the page.
You can set 'how many people'. Eg if you set it to 10, you'll get a number between 1 - 10 inclusive.
You can set how long the decision takes. While it's thinking, you'll see an exciting spinning number.
