The easiest way is when you have a special chip (not the eating kind) in your DS and you tap on the game, check the cheats list and tick the one you want before actually playing the game. But if you don't have a chip, like me, you have to search hard and get all three in one course and once you do you should have about just over a hundred star coins. If your talking about the Wii, ask a more specific question like, "How do you get 99 star coins on new super Mario Bros on the Wii" but if you are not talking about NEW super Mario bros then ask another more specific question.
203 star coins
get all the star coins.
yes
there are 240 star coins. 3 in each level
Find the hidden entrances and get all star coins for that world.
You can't.
In order to get ALL of the Star Coins in Super Mario Bros. Wii, is to just try your best. If I were you, and I were clueless where one Star Coin is, I would search on YouTube. Example: If you needed to know where the Star Coin in World 3-4 is, search NSMBW Star Coins World 3-4 on YouTube.
You have to get all the star coins in 6-6.
No, but if you get all the Star Coins in a world, you unlock a level in world 9.
yes and it is a city but to get it you have to get all the star coins in world 9 sorry if I am mixed up with[super mario galaxy]
hit all squares
Get all the star coins.
