You go into the lottery store clutching your handful of tickets ready to cash in. You know there are winners in that pile.
You're in the queue, and a few moments later you notice a couple of guys move in behind you. They're big, look a little tough, swaggery.
You step up to the counter and the girl starts putting them through the machine.
After just a couple of tickets the till chimes the winning sound. Great!
Then again! And yet again!

Now you're starting to get a little uncomfortable, sure the guys behind are mentally adding up the prize money.
I wonder if I'll be a target for them when I step outside, you think.
Why can't they turn the ring chimes off so I can keep my multiple wins secret!

Well, unfortunately they can't.
Many lottery organisations require their stores to have a ring sound as a safety net for both the customer and the retailer.
The ring sounds acts as an alert so there can be no chance of anyone forgetting to pay out, or concealing a winning ticket from the customer.

Here's the screenshot for the moment when the New York store clerk steals a customer's lottery ticket.
The National Lottery terminal will emit the 'win sound' every time a winning Lottery Draw Game ticket or Scratchcard is scanned.
Retailers have always had to inform a player if they have won a National Lottery prize. The 'win sound' simply standardises the process for how players are alerted to the fact that they are in possession of a winning ticket – it does not indicate how much the player has won or any other details.
And if a different sound means a big win over the retailer's cash payout limit, the retailer is not obliged to tell you the amount you've won and will refer you to the lottery headquarters.
