If you downloaded Miitomo last month, you probably had to sign up for the My Nintendo Rewards program. Well if you can remember your username and password, you can head to the Rewards page to get discounts on big Nintendo games and even some freebies.
If you’ve purchased Nintendo games digitally, you’ll get some gold coins that you can use for some discounts on Wii U and 3DS games. Some of the notable deals are %30 off Kid Icarus: Uprising, Fire Emblem Awakening, and Mario Kart 8. Considering that first-party Nintendo games don’t usually go on sale, this is a pleasant treat.
For those with a good amount of gold coins, you can even get some free virtual console games. The excellently underrated Wario Land 3 is 40 coins for 3DS, and Super Mario Kart is 60 coins for Wii U. You might want to check your account, you might have some extra coins lying around.
