List of Super Mario Bros. 3 glitches

These are the glitches found in Super Mario Bros. 3

The player must be Raccoon Mario or Tanooki Mario to perform this glitch. In a level with quicksand, Mario must run and fill the P-meter. Afterward, he must touch the quicksand and jump right after. Flying up, Mario will appear to be walking while flying up and back down.

An easier way to do this is to use a P-Wing.

When stomping on chains of enemies to get increased points and 1-Ups, if the fifth or later enemy is a Boomerang Bro, it will register as a 1-Up instead of the next point value (i.e. 100-200-400-800-1-Up instead of 100-200-400-800-1000). This can be achieved in World 1-3 and 2-4. This glitch was fixed in Super Mario All-Stars.

In the Fortress level of Dark Land, the player must go through several doors in order to battle Boom Boom. There are some Question Blocks which contain items near a door. If Mario hits one of these blocks and enters a door quickly, before the item appears, the next time he goes to that area the block will be permanently used. It will stay there until losing a life or completing the level.

If Mario is standing on a falling Donut Lift and another Donut Lift is under him, he will simply pass through it. This glitch was fixed in the Super Mario All-Stars update.
 * Found in: World 6-7

The player must have Mario wag his tail a fraction of a second after collecting a 1-Up Mushroom to hear an extended 1-Up sound effect. The exact moment to wag Mario's tail at 1/12 of a second after the 1-Up icon appears. The two sound effects will conflict, causing the game to play extra notes at the beginning of the 1-Up theme.

It is possible to remove Bowser's ability to spit fire. It works in the NES version and the Super Mario All-Stars version, but not in the Super Mario Advance 4 remake.

The player must use a magic P-Wing before entering Bowser's Castle. After climbing the diagonal corridor protected by Roto-Discs, before descending, the player should collect the hidden 1-up mushroom. Then, the player should crouch and fly between the spent block and the ceiling, then stand up. The player will glide through the wall (This isn't necessary for the trick to work, but makes it easier to continue without losing the P-Wing powerup). There are actually two separate Bowser rooms and this trick requires that you make your way to a specific one. The easier path to Bowser goes through a room with lava and donut lifts, but the trick cannot be performed if you enter the door at the end of that path. The other path to Bowser goes through a room with lava and solid platforms. This is the one where the player should enter the door to Bowser's chamber. However, reaching the correct door / chamber without losing the magic P-Wing can be difficult. Normally, reaching this room requires the player to pass a Thwomp that is made more-difficult because the magic P-Wing slows the player's descent...causing the player to lose the powerup and the trick cannot be performed. There is a way to reach this room without encountering the Thwomp. Simply take the easier path to the room with donut lifts over lava. Do not enter the door to Bowser's chamber. Instead, crouch and fly between the statue and the ceiling and the player will be forced through the wall. This will lead to the other Bowser chamber. DO NOT squeeze through the ceiling a second time, because the player will be stuck in the side of the screen until the time runs out.

After entering Bowser's chamber, the player should fly straight up, then over the wall to the left. The player will land in Bowser's alternate room and fight him there. He will make belching motions, but will be unable to produce fire. Bowser also can't hurt the player when crouched, so the player can easily defeat Bowser by simply staying crouched in the middle until Bowser's final jump, then simply move out of the way and let Bowser fall through the floor.

This works in the NES and Super Mario All-Stars versions, but not Super Mario Advance 4.

The player has to go to Bowser's Castle. After passing the Donut Lifts, the player will have to take the upper route. The player will follow the route until Mario or Luigi reaches the door at the end. Instead of entering it, the player must fly to the Bowser statue just before it and ducks. The player ducks on top of the Bowser statue, and after doing so the player has to fly through the wall. This will make the player end up in the room that would have been reached if the player had taken the lower route found after the Donut lifts.

Another type of glitch similar to this is also possible. By ducking and jumping at the top right corner of any wall in any level, then releasing the down area on the, the player will go through the wall. For some levels, such as the World 1 Fortress, it acts as a shortcut; for others, it simply leads to an empty area.

As Tanooki Mario, if the player presses right as Mario goes down a pipe, he will turn grey, but not into a statue. However, after the player leaves the pipe, Mario will return to normal.

As Tanooki Mario, if the player grabs a Hammer Suit and turns into Statue Mario right before, Hammer Mario will have a monochromatic color scheme, as if he was made of stone. However, he cannot go back up the pipe that leads him out of the room, leaving him trapped.

This glitch can be found in World 6-10. The player follows the route until they reach a pipe with the Hammer Suit in it. If Mario enters the secret room and breaks the ? with the Hammer Suit, he will go up to the top of the hill, and he will still slide even with the Hammer Suit on.

If the player flies directly under a block containing a P-switch, it is possible to get "under" the block and activate the P-switch from below. This can also be done with question blocks with Power-Ups in them.

In world 1-1, there are some Paratroopas. Mario needs to jump on one of them when they are at the highest point of the bounce. Mario will go offscreen and will not come back. He is actually in the bonus area although the screen didn't scroll there. If he hits the block that has the 1-up mushroom, the block is visible on the bottom side of the screen while it's being hit.

By grabbing an Ice Block at the exact moment a Buster Beetle grabs the same one, both Mario and the beetle will be holding an Ice Block.

This glitch works only in Super Mario Advance 4: Super Mario Bros. 3. To do it, Mario or Luigi must have completed World 2-Pyramid. It will have a "completed" white icon, however, if Mario goes to the left, so that the level is off-screen and back, the icon will turn yellow.

This was shown in a Super Mario All-Stars Limited Edition Super Play video. To do this, Mario must stand on two donut lifts and one of them won't fall.

This glitch has not been tested outside the Super Mario All-Stars version. However, it should be impossible in Super Mario Advance 4 and most likely would require getting a game over on purpose in the original due to the lack of a save feature. In All-Stars, the player must start a new game, get the 2 warp whistles, save and quit, then return to this save-game. The castle will remain destroyed, but all other completed levels, toad houses, spade panels, and the hammer bro. will re-open. The player can then re-play level 1-3 to get a 3rd warp whistle, and replay any other levels required to get any other extras he or she wishes. The player must then save and quit, return to the game, and repeat these steps as many times as he or she wishes, or until the player's inventory is full.

This glitch works in the Tower in World 5. First, the player must start the level with a P-Wing. The player must fly to the area full of bricks. (There should be two Micro-Goombas there too). The player must then fly to the pipe, then go above it, and keep going right until they get over the pipe into an area behind it. There is also a brick with a 1-Up back here. Over to the left, the player should see a wall of bricks. Mario must then fly over to them and whip them with his tail to make a spot to stand on. The player must then make Mario fly upwards off the screen for a while, he or she will start seeing "invisible" blocks being broken at the very bottom of the screen.

At the end of the second Muncher level in World 7, Mario must fly up to the top of the thin pipe at the end. By landing, Mario will progressively lose all his power-ups for an unexplained reason until he eventually dies. The glitch is fixed in later releases.

This glitch is easier on 4-1. At the two blocks where the red Koopa walks, the player has to make the brick block and Question Block on the other side be partially showing. Then, the player must kick the red Koopa's Shell into the two blocks. It will bounce off the Brick Block.

This glitch works only in the Japanese version. To do this glitch, the player must go to Water Land with at least one Warp Whistle in the inventory. Then, the player must get a Hammer (one of the world's Hammer Bros. owns one) and use it to break a rock blocking the way to the Boat and board it. While in the boat, use a Warp Whistle. Mario will be in the Warp Zone. The player can move to left and Mario will leave the place and move him as if in a boat. If the player goes far right, the screen will move and reveal a black background and the world numbers will move too and the game will turn glitchy. Mario can move left again. It will be impossible to reach land again.

The game can't stand with two or more items in the screen, so, if there's an item in the screen and another appear, the first item will disappear.

With Tanooki Mario or Tanooki Luigi, the player must enter a Koopaling battle, then fly up to off-screen and turn into Statue Mario or Statue Luigi. The "poof" smoke will be in the ground, however, Mario will not be there.

This glitch is only possible in the NES version. This is a glitch from level 3-9. In it, the player plays with the Ice Blocks on the right side of the Pipe as follows: Mario ducks, getting rid of the bottom 3 ice blocks on the right side of the pipe, but keeping the ice block on the far top. Then he must duck and jump and he will suddenly go down the side of the Pipe. Fire Mario can still shoot fireballs, but Mario won't be able to get out of the pipe. The player can just scroll left and right, but Mario won't appear. Moreover, the player won't return to the map screen until 5 minutes after time runs out. This glitch is also possible in levels 5-2 and 7-5.

This glitch is possible in the Super Mario All-Stars and Super Mario Advance 4 version of the game. To perform this glitch, the player must hit the button to transform from Tanooki Mario to Statue Mario right as Mario collects a third panel that matches the other two from the Roulette Box. If done correctly, the ending will play out normal at first, but a single sprite will appear on the screen and the game will freeze. If the glitch is performed in the Game Boy Advance version, to see the effect the player must watch the replay if it is possible.

The player must first use the through the wall glitch in the area the Tanooki Suit is found in World 4-5. After reaching the other side of the wall, the player must then jump on top of the bonus area quickly. He or she then has to leap forward off the top of the wall. They will find a secret area, consisting of a pipe and a level ending.

This can possibly be a leftover of the Japanese version's World 5-1 exit.

This glitch is only possible in the Japanese version of the game. It is recommended that the P-Wing be used for this. At the end of level 5-1, after entering the warp pipe at the end of the stage, the player must fly up to the top of the of blocks behind the pipe, and run across. The secret area that appears at the beginning of the stage will be below the player, and the sound the chest makes when it appears in that area will play. The player must then land back at the bottom of the stage, and head to the end of the stage. The Nipper Plant and Panels will appear glitched. When the stage is completed, a chest will appear on one side of the stage. It is possible to make the chest land on the side the player will leave the stage and collect it's contents, but the "COURSE CLEAR! YOU GOT A CARD" text will appear glitched.

The glitch was fixed in the U.S. version, as the goal was moved to the same area as the level.

This works in the NES and Super Mario All-Stars versions. Whether it works in Super Mario Advance 4 is a meaningless question because a Fire Flower changes Small Mario to Fire Mario normally in Super Mario Advance 4.

This glitch is in level 5-7. The player starts 5-7, and Mario must be Super Mario. Mario must jump into a block to make a Fire Flower without getting it right away. Instead, Mario collects the first coin to the right of the flower and it starts to flash. Then, a Micro-Goomba hits Mario so that he can downgrade to small, and he grabs the flower, and he becomes Fire Mario immediately.

This glitch can be performed in 6-10. Mario needs to start the level with Star (without Frog Suit). The player must then quickly break the Brick Block with Vine and climb on it. Mario will still somersault even when he loses his Star.

Firstly, the player must get a Tanooki Suit and use it. Then, go to a level which contains a door. Mario/Luigi must turn into Statue Mario right above the door and press up on while in front of it (while Mario still Statue Mario). He enters the door normally, but a small fog will appear above the door and Mario will fall from it.

To do this glitch, the player must wear Tanooki suit, then go to a Giant ? Block with a Frog or Hammer Suit in. When the item jumps off the block, they must stand near it and turn into a statue. When the item hits Mario, he will be a statue-colored frog or Hammer Bro. This glitch is fixed in later releases.

In the second fortress of World 5, the player can jump on top of the pipe and up the solid blocks above, becoming wedged between that area and the right side of the screen. The player can then jump to the top of the ceiling and "crush" Mario, losing a life.

In the beginning of 5-2, If Mario has a Tanooki suit, he must transform to a statue on the slope, then he slides down the slope to the far left of the screen, and dies.

This glitch only works in NES version. In 5-3, with a Super Leaf or Tanooki Suit, the player must hit a Spiny and hold its shell. While doing so, Mario has to get into a Kuribo's Shoe. The shoe will become transparent and Mario's clothes will become black.

To do this glitch, the player must land in a Kuribo Shoe while in statue form. Mario will be grey, and everything will play normally, except Mario will be invincible. However, Mario can't enter pipes, so he needs to get another power-up to enter them.

When Mario's foot catches off a pipe or wall, he can jump again to do a wall jump.

By jumping down a Venus Fire Trap-inhabited pipe in World 5-7, the player can use the white block to head behind the scenery. The player must then use the warp pipe to get back to the normal level before this wears off. If done correctly, Mario cannot be touched by anything (power-ups included).

Miscellaneous
Other programming anomalies that are not glitches are listed here.

If there are two Hammer Bros on the Map and they move into the same space, the game will allow them to move again until they are not on the same space which can lead to them getting stuck with each other and not stopping.
