There isn't really any need to save up. You can only buy 1 fortune cookie a day so you the most you need is 2 play coins a day. 200 steps
I've got 23... It would probably be a good idea to jog with the 3DS in my pocket? Or does running not register? Does anyone know by any chance? ._.
I put mine in my bag whenever I go someplace, and try to carry it with me around the house when I'm doing chores. If I'm just at my desk with little to do, then I'll shake it around for a minute or so to get my coins.
I always take my 3DS around with me, so always earn my 10 coins a day. Now that I've fully completed StreetPass Quest, the only thing I spend the coins on are blue puzzle pieces if there's a new StreetPass puzzle out. I'm now buying two fortune cookies per day in New Leaf, so that's 4 play coins a day. I'm so pleased that finally there's a game out that makes decent use of the feature!
I had 300 last Saturday but I started spending them like crazy on Puzzle Pieces and Find Mii. I have 200 right now. I'm trying to get 300 again but it's pointless. lol I just like the fact that I have the maximum that you can get. I really hope I get Majora's Mask as my first item. I want it so bad!
The only LoZ thing I saw, was from what I believe was the very first major trailer of the game. The one with the master sword. I want it. :I *grabbie hands*
