I bought my N3ds 5 days ago. FW 9.0. I streetpassed my other 3ds xl fw 9.5 that has 35 panels complete. I'm using playcoin hb on my n3ds so I can have 300 coins all the time. After 7 complete puzzles I'm not getting any mark on the puzzle swap game. All other streetpasses works perfectly on the n3ds. I have 6 people in my plaza on the n3ds. Is there some restrictions for how many puzzles you can get each Week? Or any other restrictions?
