From December 2001 to January 19th 2002, Coca-Cola Japan made a campaign to promote the movie "Harry Potter and the Philisopher's Stone". If you got a winning symbol in your bottle/can, you were rewarded with a free cinema ticket. Otherwise, you could send back 3 losing symbols to participate in a lottery to try to gain one of the 1000 Harry Potter to Kenja no Ishi Playstation prizes.
