Most people think they’ve played every classic Mario game, but they’re usually wrong about the sequel. Back in 1986, if you lived in Japan, the follow-up to the most famous platformer in history wasn't the quirky, vegetable-tossing adventure we got in the West. It was something way more punishing. Super Mario Lost Levels—or Super Mario Bros. 2 as it’s known in its homeland—is basically the "hard mode" version of the original game that Nintendo of America was genuinely terrified to release.
They thought we’d hate it. Honestly? They might have been right at the time.
Howard Phillips, a key player at Nintendo of America in the 80s, famously playtested the Japanese sequel and found it to be a frustrating, soul-crushing experience. It didn't feel like a "fun" progression. It felt like a trap. Because of that, we got a reskinned game called Doki Doki Panic instead, while the "true" sequel stayed hidden in Japan for years. It’s a weird bit of history that fundamentally changed how we view difficulty in gaming.
Why Super Mario Lost Levels is a Total Mind Game
The first thing you notice when you fire up Super Mario Lost Levels is that it looks almost identical to the first game. The sprites are roughly the same, the music is familiar, and the physics feel right. But then you hit a block. Instead of a mushroom, a purple, angry-looking "Poison Mushroom" pops out. If you touch it, you die or shrink. That’s the game’s mission statement right there: everything you think you know is a lie.
It’s a game designed by people who knew players had mastered the original. Shigeru Miyamoto and Takashi Tezuka weren't trying to onboard new fans; they were trying to break the experts.
Wind pushes you off platforms. Warp Zones actually send you backward to earlier worlds. To clear certain gaps, you have to bounce off a flying Koopa Paratroopa at the exact frame of its peak height, or you'll plummet into the abyss. It’s mean. It’s really, really mean. But there’s a strange sort of brilliance in how it forces you to unlearn your muscle memory. You can't just run right and hope for the best. You have to be precise.

The Luigi Difference
One of the most significant mechanical shifts in this game is the differentiation between Mario and Luigi. In the first Super Mario Bros., Luigi was just a green palette swap. In Super Mario Lost Levels, he became his own man. Luigi jumps significantly higher and floats longer, but he has almost zero traction. He slides around like he’s wearing buttered shoes. Mario, meanwhile, remains the grounded, reliable standard.
This choice actually matters for the level design. Some jumps are technically impossible with Mario, requiring Luigi’s verticality. Other sections with tiny platforms are a nightmare for Luigi because he can’t stop sliding. This was the birth of the "Luigi Physics" we still see in games like Super Mario Wonder today.
The Famicom Disk System Factor
You can't really talk about this game without mentioning the hardware. In Japan, it was released on the Famicom Disk System (FDS). This was a peripheral that used proprietary floppy disks. It allowed for more storage than the early cartridges and, crucially, a save feature.
This is why the game is so long.
Beyond the standard eight worlds, if you beat the game eight times, you unlock World A through World D. These are the true "Lost Levels." They feature some of the most abstract and difficult layouts ever conceived by Nintendo. Without the FDS’s ability to save your progress, almost nobody would have ever seen Bowser’s final stand in World D-4.

When the game finally came to the West in the 1993 collection Super Mario All-Stars for the SNES, Nintendo added a mid-level save feature. Without that? Most kids in the 90s would have thrown their controllers through the TV. It’s a different kind of challenge than Dark Souls, but the DNA is there. It’s about trial, error, and eventual mastery.
A Masterclass in Subversive Design
Look at the level design of World C-3. You’re launched into the air by "Super Springs" that send you off-screen for several seconds. You have to navigate Mario or Luigi while they are literally invisible to the player, judging your position based on the timing of your descent.
It’s a bit of a "gotcha" mechanic.
Modern game design schools usually teach you to avoid this. You want the player to feel like their failure was their fault, not the game's. Super Mario Lost Levels disagrees. It wants you to feel like the world is actively trying to kill you. It’s the original "kaizo" game, decades before people started making impossibly hard levels in Super Mario Maker.
Misconceptions and the "True" Sequel Debate
People often argue about which Super Mario Bros. 2 is the "real" one. The truth is they both are. The American version (the one with Birdo and Wart) eventually made its way back to Japan as Super Mario USA. Nintendo basically decided that both timelines are canon.

However, Super Mario Lost Levels represents a specific moment in Nintendo's history where they weren't sure if the "Nintendo Hard" philosophy was sustainable for a global audience. They chose the safer, more experimental path for the US, and it paid off. Doki Doki Panic-Mario introduced Shy Guys and Bob-ombs, characters that are now staples of the franchise. If we had only ever gotten the Japanese sequel, the Mario universe might look a lot less colorful today.
How to Play It Today (Legally)
If you want to test your patience, you don't need a vintage Famicom.
- Nintendo Switch Online: It’s available in the NES library. This is the best way because you can use "Rewind" to fix your mistakes.
- Super Mario All-Stars: If you have the SNES app on Switch, play this version for the updated 16-bit graphics and slightly more forgiving save points.
- Game Boy Advance: There was a Super Mario Bros. Deluxe port, but the screen crop makes an already hard game nearly impossible. Avoid this unless you’re a masochist.
Actionable Takeaways for the Brave
If you're going to dive into Super Mario Lost Levels, you need a strategy. This isn't a weekend romp.
- Pick your character based on the map: Use Luigi for levels with high walls and large gaps. Use Mario for precise platforming over lava where you can't afford to slide.
- Master the crouch-jump: You'll need every bit of momentum. Learning how to slide under low ceilings while jumping is a mandatory skill by World 4.
- Ignore the mushrooms: Seriously. Many of them are traps. If you see a power-up in a weird spot, evaluate the path before you commit.
- Use the Warp Zones (but carefully): In World 3-1, there’s a warp that sends you back to World 1. Don't touch it. Always look for the destination text before jumping into a pipe.
- Abuse the save states: If you’re playing on modern hardware, there is no shame in saving after a particularly brutal jump. The developers designed this for a different era of patience.
The legacy of Super Mario Lost Levels isn't just that it’s hard. It’s that it proved Mario could be more than just a kid's game. It showed that the mechanics were deep enough to support high-level play. Even today, watching a speedrunner blaze through World 8-4 is a masterclass in platforming perfection. It’s a brutal, unfair, brilliant piece of gaming history that every fan should try—at least once. Just don't blame me when you lose your last life to a hidden block right before the flagpole.
