015 steps
Chapter 1

Worlds 1 and 2

Mission brief

Learn map items, Raccoon flight and desert hazards.

Finish line

Clear Grass Land and Desert Land, with any intended Warp Whistles collected.

  1. Step 01

    Use Grass Land to practice filling the P-meter with B held, then tap A repeatedly to fly as Raccoon Mario.

  2. Step 02

    In 1-3, crouch on the white platform near the end until Mario drops behind the scenery, then run behind the goal to reach the first Warp Whistle.

  3. Step 03

    In the World 1 fortress, keep a Raccoon suit, fly above the first room's ceiling, continue right, and enter the hidden door for the second whistle.

  4. Step 04

    In Desert Land, wait for the Angry Sun to finish each dive before crossing exposed ground and preserve a power-up for the pyramid and fortress.

  5. Step 05

    For the third whistle, obtain a Hammer on the World 2 map, break the upper-right rock, and defeat the hidden Fire Bros.

VISUAL CHECKPOINT · CHAPTER 01World 1 — early slope
What this frame provesRaccoon Mario crosses a World 1 slope with Goombas, pipes and the complete NES status bar visible. GameFabrique ↗
OBJECTIVE
Build the P-meter safely and preserve the Super Leaf.
LOOK FOR
The long slope, Goombas and clear runway before the pipe.
DO THIS
Start the run on flat ground and jump only after the P-meter fills.
AVOID
Do not take off toward an unseen pipe top; a Piranha Plant may already be active.
VISUAL CHECKPOINT · CHAPTER 01World 1 — music-block route
What this frame provesMario approaches a winged Goomba and music blocks in an early World 1 stage of the original NES game. MobyGames ↗
OBJECTIVE
Use the winged Goomba and note blocks to practice controlled bounce height.
LOOK FOR
Music blocks and the Paragoomba beside the early platform.
DO THIS
Release A after the bounce if you need a short landing instead of maximum height.
AVOID
Holding Right through the bounce can overshoot the next safe platform.
Checkpoint reached

Clear Grass Land and Desert Land, with any intended Warp Whistles collected.

Chapter 2

World 3: Water Land

Mission brief

Navigate swimming stages, bridges and the wandering royal boat.

Finish line

Open the required map routes and clear the Water Land airship.

  1. Step 01

    Equip a Frog Suit for swimming-heavy stages, hold A for faster movement, and change suits before a land-focused fortress if possible.

  2. Step 02

    Clear the map's fortresses methodically to open routes rather than repeatedly entering water stages that do not advance the bridge network.

  3. Step 03

    In Boss Bass areas, stay on raised platforms whenever possible and move only after the fish's leap has passed.

  4. Step 04

    Use fireballs to remove enemies blocking narrow water lanes, while keeping enough distance that currents do not push Mario into them.

  5. Step 05

    On the airship, remain near the center of moving platforms and fight Wendy by jumping over her rings before attacking.

Checkpoint reached

Open the required map routes and clear the Water Land airship.

Chapter 3

World 4: Giant Land

Mission brief

Handle giant enemies and alternate-size stage layouts.

Finish line

Complete the size-switching route and clear Giant Land.

  1. Step 01

    Give giant Goombas, Koopas, and projectiles extra room even though their basic defeat patterns remain familiar.

  2. Step 02

    Jump as a Sledge Bro lands to avoid its ground-shaking stun, then attack during the recovery.

  3. Step 03

    In 4-6, use the doors that switch between giant and normal layouts to choose safer terrain and reach the correct exit.

  4. Step 04

    Enter the fortress with a tail or fire power-up so Dry Bones, Roto-Discs, and narrow rooms can be handled without rushing.

  5. Step 05

    On the airship, use short jumps beneath low ceilings and attack Iggy only after his wand shot has passed.

VISUAL CHECKPOINT · CHAPTER 03World 4 — Giant Land
What this frame provesGiant Land: treat oversized enemies by their normal timing, but leave extra room for the larger collision boxes. Pia / Medery ↗
OBJECTIVE
Cross the giant-enemy stages without spending the flight item needed for later shortcuts.
LOOK FOR
The giant Koopa, oversized question block and the safe flat tile beside Mario.
DO THIS
Bait the giant Koopa into walking away, then jump after its turn rather than over its full width.
AVOID
Do not judge the hitbox by the familiar small sprite proportions.
Checkpoint reached

Complete the size-switching route and clear Giant Land.

Chapter 4

World 5: Sky Land

Mission brief

Climb from the ground into a long aerial route.

Finish line

Climb the tower, cross the cloud route, and clear the Sky Land airship.

  1. Step 01

    In 5-3, dislodge the Goomba from Kuribo's Shoe and enter it to cross spikes and defeat otherwise dangerous enemies.

  2. Step 02

    Clear the spiral tower carefully because it is the required transition from the ground portion of Sky Land to the clouds.

  3. Step 03

    Keep a Raccoon or Tanooki suit for controlled flight and tail braking around small cloud platforms.

  4. Step 04

    Use a stored P-Wing only on a sky stage that repeatedly costs lives; maintain altitude above hazards but watch for ceilings and enemies.

  5. Step 05

    On the airship, land in the center of each platform and avoid chasing Roy while his landing can stun Mario.

Checkpoint reached

Climb the tower, cross the cloud route, and clear the Sky Land airship.

Chapter 5

Worlds 6 and 7

Mission brief

Cross Ice Land and solve Pipe Land's maze-like routes.

Finish line

Clear Ice Land and solve the required Pipe Land route to its airship.

  1. Step 01

    On Ice Land's slippery floors, release the D-pad before the intended stopping point and use short hops for precise corrections.

  2. Step 02

    Carry Fire Mario into stages with frozen coins or blocks, including 6-7 and 6-10, so fireballs can open safer or more rewarding routes.

  3. Step 03

    Save a strong suit for Ice Land's fortresses, where moving platforms, Roto-Discs, and narrow ice corridors punish a small mistake.

  4. Step 04

    In Pipe Land, note which map pipes actually connect and clear the stages or fortresses that unlock the route toward the castle.

  5. Step 05

    Inside maze-like Pipe Land stages, test P-Switches and hidden blocks near the route you entered, then retreat before the timer forces rushed decisions.

Checkpoint reached

Clear Ice Land and solve the required Pipe Land route to its airship.

Chapter 6

World 8: Dark Land

Mission brief

Survive tanks, ships, Hand Traps, fortress and Bowser's Castle.

Finish line

Bait Bowser through the brick floor and restore the Mushroom World.

  1. Step 01

    Use stored Clouds or P-Wings selectively on the tank and navy routes, but keep at least one strong suit for the fortress or castle.

  2. Step 02

    Treat each Hand Trap as a separate survival room and return to the map before choosing the next route rather than rushing the sequence.

  3. Step 03

    In the Dark Land fortress, remember doors that loop to earlier rooms and commit to a new route only after checking its hazard pattern.

  4. Step 04

    Cross Bowser's Castle with patient jumps over lava, lasers, and statues, preserving a tail, fire, or Tanooki power-up as long as possible.

  5. Step 05

    In Bowser's chamber, stand over breakable bricks, move aside as he descends, and repeat until his ground pounds open a hole beneath him.

Checkpoint reached

Bait Bowser through the brick floor and restore the Mushroom World.

04

Secrets & field notes

Optional knowledge for safer runs and fuller completion.

Warp Whistles

Three whistles exist in the early game. They open Warp Zone access and can create a very short route to World 8.

White Mushroom Houses

Collecting the required coins in certain stages causes a special Mushroom House to appear on the map.

Tanooki statue

Press down with the Tanooki Suit to become a statue temporarily, avoiding many attacks and revealing a few special interactions.

05

Questions players ask

Direct answers to common progression blocks.

How do I fly with Raccoon Mario?

Run while holding B until the P-meter fills, then tap A repeatedly to gain height.

Can I save progress in the original NES game?

The original cartridge did not use a normal save system. On OldGames, use emulator save states when you need to continue later.

How do I damage Bowser?

You do not need to attack him directly. Bait his ground pound so he breaks the brick floor beneath himself.
