Super Mario 3D All-Stars was announced September 3rd.
It's a mish-mash of Super Mario 64, Super Mario Sunshine and Super Mario Galaxy.
You'll be able to play it on the Nintendo Switch.
Here's everything you need to know about Purple Coins in Super Mario Galaxy!
Purple Coins
Purple Coins are a special type of Coin, they appear in the main galaxies when a Purple Comet is in orbit.
In Super Mario Galaxy, the player will have to collect 100 Purple Coins in order to make a Power Star appear.
Sometimes, more than 100 Purple Coins can be found around a large area.
There will be some challenges which will be timed.
In these challenges, there could be over 150 coins to collect.
You don't have to collect them all, you'll only need the 100.
The player will have to explore every nook and cranny to find all of the coins.
Coins that are left behind cannot be collected at a later date as you cannot backtrack.
There are two Purple Coin missions that cannot be activated by a Purple Comet, they can be found in the Gateway Galaxy, and the Grand Finale Galaxy.
