Hello. I'm planning to do a Giveaway stream on Twitch. I got some demo codes from Nintendo on January 14th and have some questions. 1. I got the email in my language (Dutch). Will they only work with my country or does it work all over Europe? I think the Giveaway will be European only. 2. Do I need to register 'my' download code I got in the email to get the other 3 codes to work? It shows a code before I scroll down and see the other 3. 3. How to do this type of Giveaway on Twitch? It will be my first Giveaway, and Nintendo's regionlock makes it European only. All Twitch viewers are ofcourse from different countries including US, so I need a good setup for this. 4. When do the codes expire? I have to know so I can prepare as soon as possible. Thanks in advance.
