You've made it quite far, and this is the final world: World 8, known as the Castle of Koopa. This world features some of the hardest levels in the game, which require very great Super Mario Bros. 3 skills to beat.
Ludwig von Koopa is kaput, and only big Bowser, the terrible king of the Koopas, stands between you and the princess. To get to Bowser, you'll have to defeat an entire Koopa army.
This world map has multiple pipes to confuse you, similar to the preceding world 7. There are no Hammer Bros., mushroom houses or spade panels, leaving you largely on your own in this world.
There are no Toad Houses or Hammer Bros. in this world. There isn't even a secret White House to be found. You will obtain from the end of just a few stages, including the hand bridge guarded by giant hands. If you have any P-Wings saved up, they can really come in handy for certain stages.

In the second part, when you walk over the tiles marked by fireplaces, there's a random chance you may be dragged into a level by a hand. These levels are thus known as the Hand Trap levels. For the purpose of this strategy guide, they're all discussed. The third part of the world is completely blacked out, with only a small lightcone at Mario's position, preventing you from seeing the complete map.
==World 8 Big Tanks (Bowser's Tank Force)==
{{floatingtoc|float=left|limit=2}}
Bowser has called in the heavy metal, and they're rolling right toward you. Bowser's pulling out all the stops in this last world, and the challenge has never been greater! A parade of Koopa's finest tanks will fill the air with flying lead. You'll need to use fancy footwork to evade the hail of bullets!{{-}}

{{Scrolling map|SMB3 W8 T1 a.png}}
==Tanks 1==
* '''1''': These stubby cannons fire Bob-ombs as projectiles. Wait until the Bob-omb explodes and then make a dash for it. Always be watchful of cannon fire. Don't go anywhere near an exploding Bob-omb—the blast radius can be huge. Wait until the coast is clear, then leap across.
{{Scrolling map|SMB3-8-Tanks.png{{!}}1664px}}
* '''2''': Don't rush! The faster you run ahead, the more likely you are to run into easily avoidable traps like flamethrowers.
*In this autoscroller tanks come rushing to you. It is very common for diagonal and forward cannons and Rocky Wrenches to be placed such that bouncing off one usually leads you right into the other, so watch out for this.
* '''3''': Wait to see what's ahead before you jump in front of the sights of a tank cannon. Don't wait too long, however, or you'll have to contend with the tools Rocky Wrench pitches at you. Jump on Rocky's head to send him packing.
*There are some new things here: for one, you'll find cannons that shoot Bob-ombs. Since they walk around before exploding, they're a bit more dangerous. Another thing you'll see here is red Rocky Wrenches - these don't regenerate, so stomp on them once and they're gone for good.
{{Scrolling map|SMB3 W8 T1 b.png}}
*As Raccoon or Tanooki Mario, these levels provide easy ways to get tons of 1-ups if you're very good at bouncing off cannonballs repeatedly. Otherwise, you should probably not try it since it's too dangerous.
[[File:SMB3 W8 T1 c.png|right]]
*In the middle there's a ? box with a raccoon leaf inside. But because you need to duck to get it and there's a cannon shooting right into this space, it is very hard to get.
* '''4''': You can't destroy the propellers on some tanks, but you can stand on top of them. It's possible to collect the power-up on the back of the tank as Super Mario by sliding underneath the block, but it's hardly worth the danger or the effort. It's easier to grab as small Mario, so be sure to pick it up when you're passing through to super-size yourself.
*When you see lots of empty space and then a small tank, watch out - the next one has a big cannon that's going to hit you right in the face if you don't duck in time.
* '''5''': The massive cannon fires equally enormous cannonballs at super-sonic speeds. You can jump on top of them to disarm them, but it's much safer simply to leap over them.
*At the end, if you don't jump over to the pipe in time you can actually get stuck down there with no way to get out. Going down the pipe leads to a lone Boomerang Brother, defeat it to make a treasure chest appear. Open it to get a starman and to end the level.
* '''B''': A lone Boomerang Brother guards the control room. You've made it this far, don't let him get you. He should be easy compared to the tanks.
==Battleships==
In [[Super Mario Advance 4]], this level was shortened, with the removal of the first two tanks after the ? Block.
*The battleships here move up and down. If the heat on the surface is too much for you, you can just swim under all those battleships, but prepare to mash the A button a lot.
*At the beginning, there's a heavily guarded block with a Fire Flower inside. If you really dare, you could try to grab it, but good luck defending against all the cannons.
*At the end of the first battleship, wait until the next one is visible, then do a large jump over, avoiding that big cannon. There's a small cannon on the other side which you have to avoid immediately after the jump though.
*The Rocky Wrenches on the second battleship can be really annoying. it is best to wait on the topmost part (where you can hardly be hit) until the big cannon is visible. Then get to the cannon, and when the next battleship is visible, jump over. But watch out because there's another big cannon on the other battleship, which is shooting right in your direction.
*You'll probably want to use a large jump to clear that pit with four cannons. On the other hand, you can accumulate many 1-ups here easily as Raccoon or Tanooki Mario.
*At the end, directly jump over to the pipe when it's visible to avoid the last big cannon. Go down the pipe to meet your old friend Boom-Boom. Stomp him three times, feed him five fireballs or lob a single hammer at him to defeat him and to finish this level.
==Hand Trap 1==
{{-}}
{{Scrolling map|SMB3-8-HandTrap1.png{{!}}512px}}
*This Hand Trap has all the different kinds of Hammer Bros. that exist in this game. Right at the beginning you're confronted with a Fire Bro, stomp on him to defeat him easily.
*Next comes a pair of Hammer Bros. You've fought them multiple times before, and it should be trivial to do now. You can get a raccoon leaf from here if you want, afterwards jump up the brick blocks and continue.
*Now you'll see a Boomerang Bro, stomp on him as well. The last enemy is a Sledge Bro, he too should be stomped on to avoid the stun attack.
*Get into the pipe to claim your treasure - a raccoon leaf. The level will end afterwards.
==Hand Trap 2==
==World 8 Battleships (Bowser's Navy)==
{{Scrolling map|SMB3-8-HandTrap2.png{{!}}512px}}
An armada of Bowser's armored warships sets sail to stop you. A finer trio of battleships has never graced the seas. Like everything else in Bowser's underworld, these ships are armed to the teeth.{{-}}
*In this Hand Trap, there's a large lava pit with several Podoboos that you need to cross. This is really trivial and should not pose a problem at all.
{{Scrolling map|SMB3 W8 N1 a.png}}
*The pipe at the end leads to the treasure which is - again - a raccoon leaf.
* '''1''': Pound the Rocky Wrench manning the ship's gun turret. Unfortunately, there'll be plenty more to replace him.
* '''2''': Stay on the far right of the screen until you can drop to the ship's deck. Race underneath the '''?''' Block. Duck while cannonballs whiz over your head, then bust the '''?''' Block to reveal a power-up. If you're Super Mario, you'll find a Fire Flower. Stay crouched and jump to snatch the Fire Flower above the block, then use it to flame the ship's crew with ease. If you're small, collect the Super Mushroom as you duck in front of the gun barrel to the right.
* '''3''': It takes practice, but Mario can swim underneath the battleships, but if he gets pushed too deep he'll sink into the abyss. The trick is to tap {{nes|A}} as quickly as possible.
{{Scrolling map|SMB3 W8 N1 b.png}}
[[File:SMB3 W8 Stage End.png|right]]
* '''4''': You can swim under this third and final ship as well, and then hop up behind the back of the ship to access the pipe with leads to the stage boss.
* '''B''': A sea-faring BOOM-BOOM is waiting for you in the battleship's cabin. If you're Fiery Mario, use fireballs to light BOOM-BOOM. Otherwise, crush him in the usual manner.
==Hand Trap 3==
In [[Super Mario Advance 4]], one cannon was removed.
{{Scrolling map|SMB3-8-HandTrap3.png{{!}}1024px}}
*This Hand Trap has a long bridge with tons of Cheep-Cheep jumping up on you.
*There's a Fire Flower power-up on the way. Also, there's a wall which you need to duck to get through if you're big Mario.
*The pipe at the end leads to the treasure - it is a raccoon leaf.
==Aircraft==
{{-}}
{{Scrolling map|SMB3-8-Aircraft.png{{!}}1528px}}
*This level belongs to the hardest levels in the game - the level scrolls by very fast requiring almost instant jumps and then there's the Rocky Wrenches which annoy you. You may want to use a P-Wing for this level.
*The basic idea is to jump from aircraft to aircraft. But as already mentioned, they fly very fast, so you have to be very quick. Also, try to avoid the wrenches thrown by the Rocky Wrenches scattered about.
*The pipe at the end leads to Boom-Boom yet again. Defeat him like you did last time to end this level.
==8-1==
{{Scrolling map|SMB3-8-1.png{{!}}1408px}}
*If you're Raccoon or Tanooki Mario, fly straight up at the beginning of this level to discover a P-Switch in the sky. Step on it and then drop down to find a horde of coins that have now appeared.
*Afterwards, fly forward and land on the tall pipe. Go down to arrive in the bonus area (see below).
*On foot, it's a bit harder. You need to jump across all the pipes while avoiding the Piranha Plants. (Just behind the first one there's a Fire Flower if you want it). Between the first two towers of Bullet Bill shooters, there's a starman which helps a lot in this level.
*Behind them, watch the Bullet Bill shooter on the ground. The block directly above it contains a 1-up mushroom. Behind it, you need to duck to both avoid a Bullet Bill and to get through the hole - and then there's a Boo Diddley which you need to avoid as well. At least you can grab a raccoon leaf from the brick block just behind.
*You'll need to stomp off the red Para-Troopa to get past the Bullet Bill shooters. After that, use the note block to get on top of the pipe, but be sure to not fall down. Get to the other pipe, then jump to the exit area to grab the goal card.
===Bonus area===
{{Scrolling map|SMB3-8-1-bonus.png{{!}}128px}}
*Jump at the giant ? block to get three 1-up mushrooms. Afterwards, slide down the level and enter the pipe at the bottom to arrive just past the Boo Diddley.
==8-2==
{{Scrolling map|SMB3-8-2.png{{!}}1920px}}
*Deliberately sink down the first quicksand pit you see to get to a secret area. Both pipes you see here take you to the bonus area (see below).
*Jump over the first three Piranha Plants in the quicksand pit, then jump down the hill, being careful to not run into the Piranha Plants. After that, the Angry Sun from level 2-Quicksand will reappear to annoy you. You'll need to cross the first pit using the note blocks. You can also use the P-Switch hidden in a block on the hill if you want to make it slightly easier.
*When you're climbing the second hill, you can try to jump over the Piranha Plants, but it is not exactly trivial to do. On the other side, you can simply slide down the hill.
*The end is very hard. You only have two note blocks and the Angry Sun is still there. If you miss, you die. You need lots of patience to make it through this section. After this, just collect the goal card to end the level.
===Bonus area===
{{Scrolling map|SMB3-8-2-bonus.png{{!}}384px}}
*If you went down the left pipe you'll be in the left half. It doesn't really have anything other than a single raccoon leaf, so collect it and then get out.
*If you chose the right pipe though, you'll be in an area with some coins. You can try to get some of these, but you'll need to fly if you want to get them all.
*No matter which side you are on, when you exit through the pipe you'll end up in the middle of the second hill. The Angry Sun will also be absent, making this level much easier.
A monstrous hand pulls Mario into a trap. There are three Hand Traps. You'll have to fight your way out of this one. The flame lined bridge leads further into Bowser's underworld. It looks safe to cross, but no sooner do you step on to it than a monstrous hand reaches out to grab you and take you into a mini-world. If you're lucky, you can make it through without being snatched, but you may want to hesitate on the bridge and get captured on purpose; for each trap that you finish, you'll get a Super Leaf!
*This level is another contender for "hardest level in the game". Essentially, there are two sides - a blue side and a gray side. You start at the blue side, and going through any door gets you to the corresponding area in the gray side, and vice versa.
===Hand Trap 1===
*The brick block above the second door contains a Fire Flower. You'll need to be big Mario to break some brick blocks at the end to get into the door, which leads into the gray half. Be warned, you end up on a conveyor belt and are pushed into the lava right away.
You'll have to defeat all the members of the Hammer Bros. family here to make it the goal. They should be easy for you to deal with by now.
*Go to the right across all the conveyor belts and past a Thwomp until you reach a door on solid blocks, enter it to be back in the blue side. Step on the P-Switch just standing out in the open and quickly run to the right through the coins and past a Thwomp, and enter the door at the very end (it is only there as long as the P-Switch is active) to reappear in the gray half.
{{Scrolling map|SMB3 W8 H1 a.png}}
*Once back in the gray half, run all the way to the end. At the bottom, you'll see a Thwomp. Wait until it has moved to the left, then drop down and jump over it as it moves towards you. Go to the left and jump at both brick blocks - one of them has a P-Switch, the other one breaks allowing you to go up. Step on the switch and run all the way to the end to see a new door that has appeared, immediately enter it.
[[File:SMB3 W8 Hand End.png|right]]
*You're now in Boom-Boom's chamber. Once the P-Switch expires, duck and the conveyor belt will automatically take you past the spikes and to Boom-Boom. This time, the conveyor belt makes the fight a bit harder than usual. As always, stomp on him three times, feed him five fireballs or lob a single hammer at him to defeat him.
* '''1''': They may be rare, but Fire Bros. have a devastating fireball attack. Squash him for a generous 1000-point bonus.
* '''2''': First a Fire Brother, then a Boomerang Brother—it's a brother reunion! Either attack with lightning speed before he can throw boomerangs, or jump to evade them.
* '''3''': A mighty Sledge Brother is the last brother you'll have to face, and he really throws his weight around. Wait for him to hurl a pair of hammers before you pounce on him.
* '''4''': '''Super Leaf'''. At the end of each Hand Trap stage, you'll be rewarded with a Super Leaf that will soon prove critical.{{-}}
==Tanks 2==
===Hand Trap 2===
{{Scrolling map|SMB3-8-Tanks2.png{{!}}1152px}}
Make it over a broken bridge harassed by Podoboos, and you deserve that Super Leaf! Actually, it's a pretty easy stage if you take your time.
*As Raccoon or Tanooki Mario, you can actually fly on top of the air support in this level. You just need to watch out for cannonballs that shoot upward, and since you can't see yourself, they aren't easy to avoid.
{{Scrolling map|SMB3 W8 H2 a.png}}
*Despite the bombardment from above, this should not be too hard if you've already survived the first Tanks level. Just watch out for the groups of cannonball shooters on the ground and you'll do fine.
[[File:SMB3 W8 Hand End.png|right]]
*Enter the pipe at the end to get to Boom-Boom, for the last time in this game! Defeat him like you did last time to end the level.
* '''1''': The second Hand Trap consists entirely of jumping over platforms to reach the goal. You'll need impeccable timing to evade the spurting fire, but it's nothing you haven't seen and conquered before. Collect as many coins as you can along the way, except for those that put you at risk of slipping into the lava.
* '''2''': Don't stumble into the molten lava in your hurry to get to the goal. You have plenty of time, so use it.{{-}}
==Bowser's Castle==
===Hand Trap 3===
This is it! The final level! Take the high path whenever you have a choice, and stay away from any statues of Bowser you find, as they can shoot laser beams diagonally. When you reach Bowser, he ''cannot'' be killed the way his kids and Boom Boom are killed. You must stand in one spot on the bridge as he jumps, avoiding the fireballs he spits at you, and get out of the way just before he lands. His impact will smash a hole partway through the bridge; three hits in one place will drop him off the screen. The door will flash, and now you get to meet Princess Toadstool. After that, you just watch the credits, showing you pictures of things that happen in all 8 worlds. Then you can re-do the game with 28 P-wings!
A swarm of attacking Cheep-Cheeps will make this the most challenging of all the Hand Traps. It's also the longest. Use the {{nes|B}} button run to get through, and don't be distracted by the meager coins in the '''?''' Blocks.
{{Scrolling map|SMB3 W8 H3 a.png}}
* '''1''' The most difficult Hand Trap has you crossing a bridge suspended over lava while attempting to survive a hail of Cheep-Cheeps. When you have to move, move quickly. That way, the Cheep-Cheeps will be one step behind you. The best way to survive is to stay high above the bridge whenever possible. Stand on blocks to stay out of attack range.
* '''2''': If you feel like risking it, snag the power-up sealed in the '''?''' Block. If you're Super Mario, you'll have to slide underneat the wall to continue forward. The maneuver is especially difficult amidst all of the flying Cheep-Cheeps. Wait for a lull, then go for it.
{{Scrolling map|SMB3 W8 H3 b.png}}
[[File:SMB3 W8 Hand End.png|right]]
* '''3''': If you're Fiery Mario, use your fireballs to cull the annoying Cheep-Cheeps. Always keep a volley of fireballs rolling ahead of you to tag any Cheep-Cheeps as they leap. If you're not so well-equipped, make a run for the exit.
