Hello there! The giveaway creator must manually ''send'' the game after the giveaway has ended.
Also the giveaway creator may not be able to send the gift right after the giveaway has ended ( for various reasons, such as not having access to a computer at that very moment ).

Also the giveaway creator has one week time to send the game to the winner. That's by the site's rules. So winners could be patient and wait for a week to receive their gifts.You should read the site's rules. Anyways, you can see your game now.
