I don't streetpass many people, so most of my pieces for puzzles comes from play coins. The problem I'm having is that I can't get the bottom right blue piece from the play coins. I don't know how common this is, but if it affects everyone, the only way to get it may be from streetpasses. I'm wondering if anyone else had this problem and fixed it somehow?
Before anyone says so, no, it isn't bad luck. I must have used hundreds of play coins on Brain Age: Concentration Training alone trying to get that bottom right piece not to mention how many other puzzles are following the same pattern. This glitch really eats up my play coins. I should list all the puzzles to see if that could help (not listing the pink pieces obviously). All non-listed puzzles I have gotten every blue piece for.
Brain Age: Concentration Training (has just the bottom right to get)
Dillon's Rolling Western: The Last Ranger (has just the bottom right)
Nintendo Starlets (has just the bottom right)
Xenoblade Chronicles (the bottom right and only 3 other blue pieces)
The Legend of Zelda: Skyward Sword (the bottom right and only 2 other blue pieces)
Mario & Luigi: Dream Team (just the bottom right)
Chibi-Robo! Photo Finder (the bottom right and 10 other blue pieces)
Pokemon X and Pokemon Y (the bottom right and only 2 other blue pieces)
SUPER MARIO 3D WORLD (the bottom right and 17 other blue pieces)
