New Super Luigi U: Rock-Candy Mines- Castle -- Roy's Ironclad Castle

Roy's castle has stone blocks that drop into the lava to serve as platforms. They move through the lava, then stop. Hit the ? Switch to make the first Star Coin drop down with a large stone. Move quickly to avoid being crushed. There's an item block with a 1-up in it. Going forward, there are several stones dropping onto conveyor belts, so time your jumps. Ahead, some blocks will drop down and carry the second Star Coin under a conveyor belt into the lava. Run quickly over the conveyor belt and drop down on the right side to get it. Ahead is another ? Switch that makes the stones form moving staircases. Transfer to the next one, which will take you to the boss door. Roy has his Bill Blaster and will fire Bullet Bills at you. Stomp him three times to win.

To get the third Star Coin, use the red switch near Rock-Candy Mines-5 to make a path to the back door of the castle. There are more moving stones as well as Podoboos. The third Star Coin is moving on the conveyor, then drops onto a stone moving to the right. Grab it, then transfer to another stone moving towards the boss door. Beat Roy again and you'll have all of the Star Coins in Rock-Candy Mines.

New Super Luigi U: Rock-Candy Mines-7 -- Switch-Lift Express

Go through the pipe to reach the main level. There are steel crates in this level with ? Switches. Hitting the switch will cause the platform to move quickly. It will remain wherever it stops. Hit the first ? Switch to move the platform to the right. There are two ? Switches nearby. Hit them both, then walk to the left. One of the crates is in position so you can jump on it and walk right to reach the first Star Coin. Past the first Star Coin is a ? Switch under a brick block. Get the item in the nearby item block if you need it, then pound the brick block to land on the ? Switch. This will allow you to hit the ? Switch near the first Piranha Plant. Keep hitting the switches to move the crates in place so you can jump over the Piranha Plants. One of them is on a lower crate that will move and rotate under a giant Piranha Plant, so pay attention. There are a couple of Fire Bros nearby. Go past the first Fire Bro and you'll see the second one with the second Star Coin. Kill this Fire Bro and get the second Star Coin before you hit another switch. Hit the switches so you can wall jump up for coins. After that is a Fire Bro with a ? Switch on either side. Hit the ? Switch on the right first, so you can reach the third Star Coin. Hit the left ? Switch and you'll soon reach the pipe to the flag.

New Super Luigi U: Rock-Candy Mines- Fort 2 -- Sumo Bro's Spinning Tower

Go through the boss door and Kamek will make a Sumo Bro giant. Bump the Sumo Bro using the platforms below it and quickly jump up to stomp it. Stomp it three times to win. Getting on the platform to stomp it can be a little tricky as the Sumo Bro tends to land on the edge.

New Super Luigi U: Rock-Candy Mines-6 -- Spine Coaster Stowaways

The bone coaster is back and it's traveling over purple water. A giant Piranha Plant will drop down onto the bone coaster and go along for the ride unless you kill it.  The first Star Coin is above the bone coaster's path. The bone coaster will dive into the purple water, so be alert. There is a P-Switch that will make Silver Coins for you to collect. The second Star Coin is over some coins near the ceiling. After the second Star Coin, another giant Piranha Plant will drop onto the coaster, pinning you in a tight space. The bone coaster will dip into the purple water again, and you'll find the third Star Coin here. At the end, transfer to the yellow platform before the bone coaster falls into the purple water, then go to the flagpole.

New Super Luigi U: Rock-Candy Mines-5 -- Rising Piranhas

Grab Blue Baby Yoshi outside the level to help you with the enemies. This level is filled with Piranha Plants on moving platforms, so having Blue Baby Yoshi is very helpful. The first Star Coin is in the center of the path of a moving yellow platform. The second Star Coin is hidden in the square rock above the three Walking Piranha Plants. Nearby is Luigi's silhouette in the rock. Just past a Piranha Plant on a vertically-moving yellow platform is a set of three blocks. The top block has an Acorn in it. Get the Acorn, then jump back across the gap to the side with the Luigi silhouette. Jump and boost into the rock near the top of the screen. This will take you to the red goal, which opens the path to the red switch.

Past the block with the Acorn are more Giant Piranha Plants. There's a loop of platforms with one in it, along with the third Star Coin. Kill the Giant Piranha Plant with a nearby Koopa shell or with Blue Baby Yoshi's bubbles and get the Star Coin. Keep going and you'll see the regular goal.

New Super Luigi U: Rock-Candy Mines-4 -- Light-Up Lift Tower

This is a dark level filled with giant Light Blocks you can use as platforms. There are Fire Snakes here, so be careful. Step on the Light Blocks to get them to start moving. Once they start moving, the level automatically scrolls up. The first Star Coin is on the right side, blocked by Light Blocks that move away eventually. Get the Star Coin and quickly return to the moving Light Blocks. The second Star Coin is on the right wall. Higher up, you'll find Fire Piranhas. About halfway up is a P-Switch that makes Silver Coins appear. The third Star Coin is at the top of the level, in the left corner, guarded by giant Fire Piranhas. Use a Fire Flower to kill them, then wall jump to reach the Star Coin. The pipe nearby takes you to the flagpole.

New Super Luigi U: Rock-Candy Mines-3 -- Spike's Seesaws

The Spikes in this level make dealing with the seesaws more difficult. The first Star Coin is over the first Spike on the right. Take the seesaw up and go past the Green Ring. There is a Spike standing on some brick blocks. Pound the brick blocks as Super Luigi to find the hidden second Star Coin. The third Star Coin is past the second seesaw that takes you up. Stomp the Spikes and jump to the green pipe overhead. This will take you to a seesaw with a Spike in front of the flagpole.

New Super Luigi U: Rock-Candy Mines- Fort -- Smashing-Stone Tower

Grrols are everywhere in this level. There are invisible blocks you can hit to guide where they go. There are invisible blocks under the first Star Coin in the center, but get the Star Coin quickly. The Grrrols will break the blocks after you reveal them. Go up higher and you'll see a pipe on either side. Take one and you'll see Luigi's face made of stone. The second Star Coin is hidden here. Return to the main level. Near the top are tons of brick blocks. Grrrols will drop down and clear the bricks, initially forming stairs, then removing the brick blocks out of reach. Move quickly up the left stairs to a pipe. The third Star Coin is here. Break through the brick blocks to get it, then leave through the pipe on the left, which leads to the boss door. Kamek gives Boom Boom wings, making him harder to stomp. Stomp him three times to defeat him. This opens the path to Rock-Candy Mines-3 and -4.

Ground pound under the third Star Coin while Super Luigi to reach a pipe cannon that will allow you to get the coin and reach the red goal. This opens the path to Rock-Candy Mines-6.

New Super Luigi U: Rock-Candy Mines-2 -- Porcupuffer Cavern

Take the yellow pipe past the crab. The main part of the level bobs in the water. There are music note blocks that allow you to reach a pole. Bounce on the third music note block from the left to trigger the appearance of the first Star Coin overhead. Keep going and you'll see another pole near a crab. Jump up to the right to find a hidden area with the second Star Coin and 8-bit Luigi. The third Star Coin will appear below. Take the pipe at the end and bounce on the music note blocks to reach the flagpole.

New Super Luigi U: Rock-Candy Mines-1 -- Mount Fuzzy

There are mine rafters at the start of the level and Fuzzies moving on paths. High up on the left side of the rafters is an invisible block with a Mini Mushroom. There's a mini pipe later on in the level that will lead you to some coins and 3 1-ups. The first Star Coin is in the center of a path with brick blocks and Fuzzies. Use a shell to get it. Go past the Green Ring and you'll see Fuzzies jumping in the air while moving on paths. Use the Ice Flower to freeze the Fuzzies and use the Fuzzies as platforms to stand on for a short while. The third Star Coin is in the center of another ring of Fuzzies. Freeze the Fuzzies so you can stand on them to reach the third Star Coin. The flag is nearby.

New Super Mario Bros. U: Rock-Candy Mines- Castle -- Roy's Conveyor Castle

The castle is filled with conveyor belts carrying large blocks which can crush you. Some of the blocks form stepping stones in the lava. When you reach solid ground, you'll see the first Star Coin under a ledge. A set of three blocks will fall. Let the first two fall, but run before the third falls because it will block access to the Star Coin. There are conveyor belts under the lava which allow the blocks to move through the lava in some spots. Ride one of the blocks moving to the right and you'll see gaps in the low ceiling. The first two gaps have coins in them, but the third one does not. Wall jump up the third gap to the hidden pipe above. It leads to a room with the second Star Coin on the right, next to a conveyor belt. Run quickly to get the Star Coin before blocks drop in to cover it. When you return to the main level, there's a Red Coin Ring near the midpoint. Past it is a ? Switch that makes blocks and Dry Bones drop from above. You'll need to hit the switch to make it to the boss door. Don't worry about the third Star Coin just yet. Go through the boss door and launch from the cannon to Roy's Airship. Oddly enough, this battle takes place outside. Roy Koopa Jr. has a bazooka-style Bill Blaster. Flying platforms will appear overhead. Stomp Roy, preferably before he can fire any Bullet Bills. Three stomps will defeat him. This opens the path to Meringue Clouds. To get the third Star Coin, take the path behind the castle. There's another ? Switch that will make blocks fall. Let the first few form a path in the lava, but move quickly and run under the ledge for the third Star Coin before a block blocks your path. Keep going to the left for blocks that will move through the lava to the boss door. You'll have to duck before you reach the boss door. Defeat Roy again. We now have all the Star Coins in the Rock-Candy Mines.

New Super Mario Bros. U: Rock-Candy Mines-7 -- Shifting-Floor Cave

This level has more of the orange platforms you can hit from below. Use them to reach the pipe to an underground area with Spike Tops and bats. Ahead are the shifting floors- walls and floors that appear from central pillars. You'll have to time your jumps because some pillars make walls to block you off and make you fall into the void. The first Star Coin is in a set of three pillars. Drop down when there's a floor below it. Be aware of the giant piranha plants on the ceiling. Past them is the midpoint. Past the midpoint are Spike Tops on some orange platforms. After that are more shifting floors. One part of the floor moves straight up. Jump up as Super Mario to break the brick blocks overhead, then run over the ceiling for the second Star Coin. Next is a Koopa and giant Piranhas on a moving floor with no gaps. Use the shell to kill the Piranha Plants, then use it to get the third Star Coin, which is under the pipe at the end. The pipe will take you to the flagpole. This opens the path to the castle, a Mushroom House, and loops back to the path after the first Fort, for easier navigation.

New Super Mario Bros. U: Rock-Candy Mines- Fort 2 -- Screwtop Tower

Screwtops make a return. Stand on the screw and spin to make the platform move. Take the first screwtop to the pipe. This takes you to the main tower, which has more screwtops and orange platforms Mario can only bump from below. He can't go through them. You'll have to go around to stand on them. There are firebars in this level you'll have to dodge while standing on the screwtops. Take the yellow pipe to an area with the first Star Coin. Use the POW Block to get it. Up ahead are Sumo Bros, but these ones shoot down lightning when they stomp. They have spikes on their heads, so you'll have to bump the orange platforms below them to get rid of them. Keep going up to reach the midpoint. The second Star Coin is high over the next Sumo Bro. Use the screwtop and dodge the firebar to get it. Bounce from the noteblocks and go up to reach the Red Coin Ring near the top of the level. You'll have to deal with L-shaped firebars to get them. There is a Sumo Bro next to the boss door. Get rid of it, then jump above the orange platform for some invisible blocks. There are three tiers of invisible blocks over the platform. The top tier will allow you to reach the third Star Coin. Through the boss door, Kamek will make a Sumo Bro a giant Sumo Bro. It will jump on some of the orange platforms. This battle is a little tricky. You'll have to bump the Sumo Bro from below, and knock it down to a level you can reach, then stomp it. You'll have to stomp it before it gets back up. Try bumping it to the floor, or one of the lower orange platforms, but you'll have to run around to jump up to stomp it. You can bump it from below as many times as you need. Stomp it three times to win. This opens the path to Rock-Candy Mines-7.

New Super Mario Bros. U: Rock-Candy Mines-6 -- Thrilling Spine Coaster

This level is pretty dark, but there are some sources of light. Ignore the mini pipe at the beginning because being Mini Mario will put you at a disadvantage. Carefully go to the right to find the bone coaster. The bone coaster travels over purple water. The first Star Coin is over the bone coaster. The bone coaster has headlights that will briefly shine on it. It's after the second dive. Soon after is a Red Coin Ring. The bone coaster won't go into the water until the 8th Red Coin. The P-Switch makes blocks below the coaster so you can reach the coins below. Be quick to return to the coaster. At the top of that hill is an item block with a Starman, which lights up everything. The coaster will then dive into the water a few times. You will then go into a tunnel with Spike Tops on the ceiling. The coaster will speed up. As soon as you get out of the tunnel with the Spike Tops, jump for the second Star Coin. The coaster will dive four times then drops at the pipe at the end. If you still have the Starman, hit the item block in front of the pipe immediately to get another Starman. Go through the pipe and quickly run and drop down to the Nippers below. The third Star Coin is above them. Run back before the power runs out. Go to the right on the rocks above the Nippers for the flagpole. This opens the path to the Fort.

New Super Mario Bros. U: Rock-Candy Mines-5 -- Walking Piranha Plants

Before you start the level, you can get Blue Baby Yoshi. Some of the rocks in the level will tilt when you stand on them, and eventually fall off. There are chains in the level to swing from. The walking Piranha Plants will move around, then stop and stretch their necks. In the area with three Piranha Plants and a Koopa, use the shell on the lower right rock to get access to the first Star Coin. There is a large gap in the ceiling next to a Piranha Plant and a chain near the area with platforms. Use the Acorn Mushroom to fly up into the gap to a new area. Hit the P-Switch, stand on the brick blocks, and fly to the left, then boost for the second Star Coin. Past the random item block and midpoint is a Red Coin Ring. There are moving platforms ahead with Walking Piranhas on them. The red pipe in the ground will give you some coins. The third Star Coin is under a ledge. Run and fly under the ledge, stick to the wall, then boost to it, then wall jump to safety. Go right and under a ledge for a green pipe to the red goal. This opens the path to the Fort and a red switch. Otherwise, keep going to the right and swing from a chain to the regular goal. This opens the path to the Fort through the blue switch.

New Super Mario Bros. U: Rock-Candy Mines-4 -- Light Blocks, Dark Tower

This is a dark level, with large light blocks that light up in sets. They also act as platforms. In the left item block is a Starman that lights up the entire level. Try to reach other item blocks to continue the chain of Starmen so you can see. Go up the wall on the right with the bats for the first Star Coin. Climb the rope ladders and go through the yellow pipe on the right side. This will take you outside, where there is plenty of light. Bounce off of the Parakoopas to get the second Star Coin. Return to the pipe to return to the main level. The green pipe at the top will take you to the midpoint. There's a ? Switch that turns on the light blocks temporarily. Keep an eye out for other ? Switches so you know where you can turn on the lights again. There's a pipe that makes an infinite amount of Bob-ombs. Go up the right side of the level past the Bob-omb pipe. There's a Fire Bro at the top of the level and the third Star Coin is above it. Take the pipe to the flagpole. This opens the path to Rock-Candy Mines-5.

New Super Mario Bros. U: Rock-Candy Mines-3 -- Waddlewing's Nest

This level has several Waddlewings (flying squirrels) and Chomps. Pound the brick blocks to the right of the Chomp on the ground for some coins. There's a red pipe to the right of some Piranha Plants. This will take you to a room with four sets of brick blocks in the floor. The second set of brick blocks from the left has the first Star Coin. Pound the brick blocks to reach it. The other sets have other things. Return to the main level and go up and to the left. If you release the Chomp by pounding its post and it goes to the left, you can reach a hidden area with note blocks and brick blocks. The middle brick block has a 1-up. Go up and over to the left for a hidden area with a P-Switch. This creates a trail of Silver Coins over coins that turned into brick blocks. Follow the trail quickly to reach the second Star Coin. Keep going up to the midpoint, then to the pipe. The pipe leads to an area with a platform that slowly lowers. This part has lots of Waddlewings walking and flying around. Wall jump up the right side for the third Star Coin. There's a Red Coin Ring in the area. Stay to the right to easily reach the flag pipe to the flag. There are Chomps at the bottom you'd have to deal with otherwise.  This opens the path to Rock-Candy Mines-5.

New Super Mario Bros. U: Rock-Candy Mines- Fort -- Grinding-Stone Tower

This Fort has lots of spiked balls rolling around. There are moving pipes in the level that push them around. The level also features Bony Beetles. Over a horizontal green pipe is a hidden area with a block with a Mini Mushroom. This will make the level more difficult, but you'll need it to get some of the Star Coins. There is a mini pipe on the left wall. Dodge a large spike ball and run under it to get the first Star Coin. The second Star Coin is on the right side in a hidden area with three spike balls under the midpoint. Do not get a power-up yet; you have to be Mini Mario to get the third Star Coin.  Above the midpoint are more moving pipes and spike balls. In an alcove to the left are some coins. The alcove above it and to the right has a Red Coin Ring. Next are lots of moving pipes and spike balls dropping down. There are few safe spots, so stay alert. As you climb, you'll see spots where the spike balls are coming from. One of them on the right wall is next to a mini pipe. With good timing, dodge the spike balls and go through the pipe. This leads to a vertical area with large spike balls rolling around on platforms. With good timing, jump straight up to the top of the level, carefully jumping up to each platform. At the top is the third Star Coin and a pipe to the red goal. This opens the path to Rock-Candy Mines-6.

 If you do not go after the third Star Coin, continue up the maze of pipes and spike balls to the boss door. This time, Kamek gives Boom Boom wings. Boom Boom flies around and swoops down, but does not land. You'll need good timing to stomp him. Stand nearby so you can stomp him as soon as he gets up, because he flies off quickly. Defeating him opens the path to Rock-Candy Mines-3 and -4.

New Super Mario Bros. U: Rock-Candy Mines-2 -- Porcupuffer Falls

To access this level, hit the red switch for the blocks that make a path to it. Take the pipe to part of the level which is underwater. The Porcupuffer will appear soon to make your life miserable. If you've got a Fire Flower, you can get rid of it for a few seconds. Swim up and get out of the water. There's a sign with an arrow pointing down. There's an invisble block on the right wall nearby. Use it to go up and over, and drop to the first Star Coin. Make sure the Porcupuffer's not directly below you. Go past the Cheep-Cheep and the pipes with currents. There's a Red Coin Ring before the midpoint. Between two red pipes are Urchins and the second Star Coin. Get it carefully. Above the random item block is an invisible block with a vine. It leads to some coins and allows you to drop down to the third Star Coin. The pipe nearby, at the end, will take you to the flagpole. This opens the path to the Fort and a set of two switches.

New Super Mario Bros. U: Rock-Candy Mines-1 -- Fuzzy Clifftop

This level is crawling with Fuzzies. They're moving around on paths, but Yoshi or a Fire Flower can take care of them. You'll get Yoshi early on, and he's useful for dealing with the Ice Piranhas as well. You'll need your platforming skills to dodge Fuzzies while standing on expanding blocks, some of which move vertically. The first Star Coin is high above a vertically moving Fuzzy. Yoshi can bounce on the Fuzzies, so be sure to have him to reach it. Soon after is a series of expanding platforms that move vertically in the midst of a loop of Fuzzies. There are a couple of ways to go about this. You can have Yoshi eat the Fuzzies, which is time consuming, or try navigating the platforms with the Fuzzies zooming around. If you do the latter, you'll want to jump on the platforms when the first one is high, the second is low, and the third one is high. Once you cross that gap, you'll reach the midpoint. Next to it is a ferris wheel to a lower part of land. To the left of the ferris wheel, under a ledge, is a pipe. Be sure to bring Yoshi. The pipe leads to an area with lots of Fuzzies over a gap and a Fuzzy in a ring above, circling the second Star Coin. With Yoshi, bounce off the Fuzzies until you can jump up to get the Star Coin and return through the same pipe. Once you return, go to the left for an invisible area that takes you back up to the midpoint. Continue down the path with the ferris wheel. Ahead is an Ice Piranha. Have Yoshi eat this one, or another one ahead, but do not immediately breathe out the ball of ice. Under one of the rocks ahead are a bunch of Piranha Plants dangling from the ceiling and on the rocks below. Have Yoshi breathe out the ball of ice to freeze the first Piranha Plant. It will drop, crushing the Piranha Plant below it. This sets off a chain reaction that gets rid of all the Piranha Plants in the area. Carefully keep going to the right to reach the third Star Coin. After that is another set of vertically-moving expanding platforms in a loop of Fuzzies. Either have Yoshi eat the Fuzzies or dodge them to reach the pipe at the end. There's an invisible area below the pipe with coins. Reaching the flagpole opens the path to Rock-Candy Mines-2 and -3.
