While My Nintendo isn't anywhere as good as the Club Nintendo was (at least for physical rewards), you can get gold coins for claiming a physical Switch game as long as you have the game card in the console. This is a feature that I often forget it exists because it's hidden away unless you press the + button on the game icon to see that it's there. I got 14 gold coins for Mario Kart 8 Deluxe and since I also have BotW and Puyo Puyo Tetris that's another batch of gold coins too. Too bad I forgot to redeem the gold coins before selling Bomberman R (never really enjoyed it very much anyway). Edit: 16 gold coins for BotW. 10 gold coins for PPT. And a correction: It says that this reward system is only for physical games so I guess very much that digital games are a no go, apparently.
