I'll be honest, these two features: Puzzle Swap Find Mii I just don't get. I spent a 300 coins last night on getting puzzle pieces and I got the Metroid and Pikmin one done. But how am I supposed to get purple pieces for the Mario Open Tennis? I get that I'm supposed to be streetpassing with people, but hardly anybody in my town or such have a 3DS. So is there any other way I can get these pieces? As for the Find Mii, I don't know how it works, I only have one person on my team and that's the Reggie Mii from some time ago, the rest of the time I'm just hiring characters. How exactly do I play this stuff and what's the best way to complete them if I'm unable to spotpass with people?
