No, this isn’t a joke, or a scam. Nintendo is legitimately offering UK 3DS owners Mario Bros Deluxe for free.
But how do I get this, I hear you cry? It’s simple really, this is a promotion that Nintendo is currently running to reward those who either register or link a Nintendo Network ID on their 3DS. This was introduced with the recent update on December 10.
Those who either register an account, or link an existing one, between December 10, 2013 and January 31, 2014, will receive a download code for the Game Boy Color title via e-mail. Don’t expect it straight away though, Nintendo has said that they will be sent out to the registered email address between February 13 and February 28, 2014.
For those of you wondering, the 7.0.0-13U update added the capability for 3DS owners to log in to an Nintendo Network ID and share/deposit digital currency through either the Wii U or 3DS.
However, if you register the wrong Nintendo Network ID on your 3DS, you can’t combine your digital balances with the Wii U.
