Sliding through Slot Car Rivals

Slot Car Rivals is definitely the most skill-based game of the third bundle, and that's saying something since all you do is hold a button and occasionally release and re-press it.  Manipulation potential is fairly low, so here come the gameplay tips.

1. You absolutely want as many people as possible for this game.  After each race, the people you've StreetPassed will make you a new booster that you'll use for the next race, and having more people working on it means it'll have higher stats.  Make use of the Plaza Update 5.0's new "Send to Line" feature if you're at a convention or in Japan or something to make sure you've got ten, and if you just can't get to ten, top off with Play Coins.
2. The stats of the boosters you get are dependent, somehow, on the properties of the Miis that make it.  All I've been able to notice so far is that short Miis affect its Speed stat, which is arguably the most important stat later on in the game.
3. Speaking of later on in the game, as you progress, you'll notice that some of the objectives that you need to complete are "Finish in X seconds.".  These times get a lot more challenging to beat towards the end of the game, and it can be very frustrating to keep getting boosters that raise your Control or Performance when all you want is Speed.
4. Getting Excellents on all the corners is your number one priority.  It's key to getting fast laps and fast completion times.  It should make sense, too, if you're not cornering as well as you could be, you're not going to be going very fast.  It should go without saying that crashing is to be avoided at all costs, though some corners are notoriously difficult to avoid crashing on, and the camera can exacerbate this, regardless of which setting you use.
5. Make heavy use of the ability to practice a track before actually racing your rivals.  This will help you get the timing down on those speed boosts and corners.  If you're having trouble beating a time objective, do Ghost Races, otherwise, just turn laps on the track to learn it.
6. Don't worry about the point requirements for each license level, there are far more points available.  You can always replay any track, any time you want, and get more points.  This effectively makes there be infinite points.  Once you beat the game, the post-game enables extra numbered license ranks for you to obtain, all the way up to S 99, as well as a "Random Track" selection that gives an experience bonus.
7. There's honestly not much else I can say.  It's all in how well you've learned each track.  Since the actual vehicle you're using doesn't matter at all, I can't suggest anything track-specific.  The game suggests specific booster stats for specific tracks, but you have no control over what you're going to get, so I just ignore it and race whichever track I want.

I hope this post helps you leadfoots keep the pedal to the metal.
