WORLD 1
Level 1 - 1
STAR COIN 1: shortly after the start of the level you will notice the first star coin clearly visible above you.
STAR COIN 2: Shortly after the checkpoint you will find the second star coin surrounded by a brick wall. Just destroy them to get it.
STAR COIN 3: Enter the green tube shortly after the second star coin to reach the third.
Level 1 - 2
STAR COIN 1: After entering the green pipe, advance until you come across three koopas trapped by bricks and with two Pow blocks on the side. Hit one to make the first star coin appear.
STAR COIN 2: enter the yellow pipe immediately after to reach the second star coin. Be quick to reach it once you hit the blue block; alternatively equip yourself with a gold flower.
STAR COIN 3: (Fire flower required). Continuing you will come to a strange tube with two ends, one of which is marked by a yellow sign with an exclamation point. Hit the latter with fireballs until a mega-mushroom comes out of the other. Mario will transform into a giant and destroy everything in its path, including the blocks that protect the third star coin.
Level 1 - 3
STAR COIN 1: (Mario Procione required). From the beginning of the level, continue until you come to a sign with an arrow pointing up. Follow the direction of the arrow while taking flight and you will reach the first star coin.
STAR COIN 2: continue until you reach a green pipe facing down from which goombas come out. Above it is another green tube that can be reached through Mario Procione: enter it and you will recover the second star coin.
STAR COIN 3: Use Mario's raccoon tail to destroy the brick wall that prevents access to the third star coin clearly visible on the screen.
Level 1- tower
STAR COIN 1: after the red ring you will come to a crossroads: keep left to get the first star coin.
STAR COIN 2: Immediately after the checkpoint you will notice a red tube on the left. Enter it, hit the blue block and before time runs out, go upstairs using the support of the snake blocks to reach the second star coin.
STAR COIN 3: exiting the green tube immediately after retrieving the second star coin, you will notice the third just above you: it will be enough to go up to retrieve it.
Level 1 - 4
STAR COIN 1: shortly after the start of the level you will easily notice the first star coin. Just go up on the mushroom-shaped platforms to reach it.
STAR COIN 2: As you continue, you will notice a blue tube at the top of the screen and pointing downwards. Enter to reach the second star coin.
STAR COIN 3: after the checkpoint, continue to a very large red platform with numerous hanging bricks. Jump into the empty space between the two yellows to bring out a beanstalk. Going up, you will come to the third star coin.

STAR COIN 2: you will find the second star coin simply by continuing through the level.
STAR COIN 3: just before the flag you will come to a suspended structure composed of pipes from each of which a piranha plant comes out. In correspondence with the left tube there is another one of which only the ends are suspended. Jump near the entrance of the latter so as to make a brick appear that will allow you to enter. Inside you will find the last star coin of the level.
Level 1 - castle
STAR COIN 1: you will notice the first star coin on a mobile platform sometimes covered by lava, while you will be suspended on a rope above. Go down with the right timing to get it.
STAR COIN 2: At the end of the rope you will notice a skeletal koopa under four bricks. Climb over the first two, jump to make some hidden ones appear, climb again and continue to the left to retrieve a Super Leaf. Once you have donned the robes of Mario raccoon, take flight continuing towards the right of the screen to reach the second star coin.
STAR COIN 3: continuing in the level you will find it dominated by a huge twomp. Drop it a couple of times to clear your way and get the last star coin.

STAR COIN 2: Once out of the tube, take the turtle shell and head left. Also in this case, throw the shell against the Pow block to get the second star coin.
STAR COIN 3: shortly after exiting the tube, three rows of moving platforms will appear in front of you. Trying to stay as high as possible, climb onto one of the back row ones and jump to the partially covered block of bricks from the top of the screen. Continue to get the star coin.
Level 2 - A
STAR COIN 1: The whole level is built around moving platforms. Climb on the fifth and when it reaches the apex, jump on the one to your left: you will reach the first star coin.
STAR COIN 2: on the ninth platform (counting the two by which you have reached the first star coin) you will find a red koopa: hit it and collect its shell. Once down, use it to collect the second coin.
STAR COIN 3: shortly after the checkpoint go up on the mobile platform and as soon as it is clearly visible, jump on the one on your left, a little higher than your position. Keep jumping on the platforms to reach the third star coin.
Level 2 - tower

Level 2 - haunted house
STAR COIN 1: in the second room, the one with the giant Boo chasing you, there are moving purple bricks. Climb on the second one you will find to easily reach the first star coin.

STAR COIN 3: Shortly after passing the red ring, you will see the third star coin floating right above your head. Just take advantage of the trampolines hidden in the floor to get it.
Level 2 - 4
STAR COIN 1: shortly after the start of the level it will be sufficient to slip into the second hole clearly visible during your ascent to reach the first coin.
STAR COIN 2: After the checkpoint, slip into the yellow pipe located shortly after. Destroy the brick on the ground and without jumping, go straight on from where it was placed. You will descend on a moving platform which will lead you to the second star coin.

STAR COIN 3: continuing you will find a cactus closed between two mini volcanoes: to reach the third star coin it will be enough to jump on the bob-ombs fired by the adjacent cannons in order to obtain the necessary momentum.
Level 2 - 5
STAR COIN 1: as soon as the dog is facing in the direction of the first star coin, clearly visible shortly after the start of the level, it will be sufficient to hit the pin that holds it chained to the ground, so as to make it destroy the bricks that there prevent you from reaching it. Alternatively you can use a gold flower or raccoon Mario.
STAR COIN 2: Hit the long pin that holds the dog chained next to the red pipe a couple of times. Once done, you will be able to access the latter.
STAR COIN 3: shortly after the checkpoint you will find yourself in front of yellow platforms of various sizes. Go down and next to the second dog, you will find the star coin.
Level 2 - Castle
STAR COIN 1: visible shortly after the start of the level.
STAR COIN 2After the checkpoint you will find a yellow brick. Once hit, grab the trampoline and use it shortly after to retrieve the floating star coin above your head.
STAR COIN 3: keep the trampoline on the platform until you see a red tube above you. Go inside and hit the first brick on the left so that a blue block appears. Once you jump on it, all the coins in the room will be temporarily transformed into bricks that will make it easier for you to access the last star coin in this world.

Level 3 - 5
STAR COIN 1: Shortly after the level begins, you will notice the star coin trapped inside a chain of blocks. Go further until you see a large boulder rolling towards you. Allow yourself to be chased so as to make it break on the blocks and get the star coin.
STAR COIN 2: Enter the yellow tube shortly after the first star coin to get the second.
STAR COIN 3: after exiting the tube, follow the arrow upwards and let yourself be “chased” by the giant boulder just above you: it will destroy the barrier of blocks that precludes access to the third star coin.
