As you probably are all aware, the step counter on a 3DS system will max out and stop giving you play coins when you reach 1000 steps or 10 coins. But thankfully, there's a very simple way to 'cheat' this entirely. Yeah it apparently causes problems with StreetPassing and stuff, but if you live in a place with very few 3DS owners (or farm country as some might say), then this is pretty much your only hope in hell of winning StreetPass Quest or Puzzle Swap.
Simply set the date back one year, then after a few coins set it back to what the original date was to unfill the step counter and get another 10 coins or so.
You can also change it back immediately after changing it and my experience is that it'll add more steps to the current total, yet still give you coins for them. Why Nintendo didn't make something like this the default set up I don't know, but it works.
It's not much of a tip and I'm sure everyone here knows it by now, but it should help those few new 3DS owners out there in nowheresville who have no one nearby to StreetPass with and need to beat Find Mii before the next apocalypse.
