Just got SpotPass news: Players in the Americas have surpassed 10 billion coins collected. As a reward, all mushroom houses we've previously visited have been reopened. And after you beat level 6, you can enter a special button combination to play as Luigi.

I noticed that the spotpass message also gave us all rainbow courses!

I stopped playing once I got all 5 profile stars. I think I had 500,000 coins or so when I stopped. Not going to bother getting 1 million just for a title screen change - I've got more enjoyable things to do. I also dont feel compelled to come back and play the game again unlike Super Mario 3D Land. To be fair I didnt for NSMB for the DS either - but I played for tens of hours after I finished the main quest on the minigames. Not having anything extra just means this will definitely be a game I end up selling - it has no replay value or minigames that keep it enjoyable.

@Geonjaha, So getting 1 million coins isn't one of the stars?

I unlocked all levels and beat them, but only have one star ATM, what do you have to do to get certain stars?

All star coins, all moon coins, all exits( normal and secret) and beat world star.

I beat the game, and star world, found all exits, just need the star and moon coins...

Happy-Mask: Did you collect all of the blue coins, or are some of them impossible?

Also get 3 Crowns worth of lives.

@Burning_Spear To my knowledge, there are several that cannot be completed, due to the fact that they flood several screens.

Ok so I have all star coins but 3, but if I collect all 3 I only get up to 9 total after spending them all, did I miss something because I currently hav found all exits and spent all coins so far, is there a secret mushroom house you need to spend coins on?

Once you get all the star coins an extra hut will open up in the Star World costing 9 star coins.
mild spoiler The hut gives you the invinciblity star item :3 /spoiler.

Thanks, friend. I'm stuck on a particularly difficult one and don't want to waste time if there are some that simply aren't possible.

@BurningSpear No Problem. I've also found that, (believe it or not) mini Mario can actually make some of the ones with crazy jumps easier.

Thanks I thought that only 9 was weird, also I can get my sparkle back by beating the level I'm currently stuck on right?

Got em all finally!

Only 10 billion coins in the Americas vs 93 billion worldwide seems kind of disappointing. It seems like barely anyone I know actually bought the game for some strange reason, so maybe it's not selling as well here.

We got the game a few weeks later than the rest of the world, and at a time when I would imagine a lot of people were enjoying their last week of summer before returning to school.

Got 4 sparkly stars, one more to go

Woo five stars!

Barely any coins though, and it'll probably remain that way for a looooong time.
