From March 2011 right up to Nintendo's latest upgrade in Puzzle Swap this year, no matter my mood, it was ONLY Puzzle Swap which kept me excited about streetpassing with others on a regular basis. I liked those adjustable-view 3D panels and the difficulty required to obtain each piece. Now I can get 10 days' worth of progress in ONE day! Thankfully another minigame filled this newly-found void!
