Molton Brown bubble game

I played the Molton brown bubble game hundreds of times last year and win nothing. This year I expected the same. I couldn’t believe it when on my first go or came up saying congratulations you are a winner Also it says it will send the prize but I had no proof I’d won as it just gives the congratulations message but doesn’t ask for further details. Therefore I was worried how to prove it if it didn’t turn up. However today I got a box with a pink peppercorn hand cream and bubble bath bauble I’ve never even won an instant win before
