Super Mario Bros: The Lost Levels Enhanced is an action platformer for the Super Nintendo Entertainment System that builds upon the foundation of the original Super Mario Bros. 2 (Japan) — the game released in Japan in 1986 as a direct sequel to Super Mario Bros. but famously withheld from Western markets for years due to Nintendo of America's concerns about its steep difficulty. The original Famicom Disk System release, known in Japan as Super Mario Bros. 2, introduced a host of punishing new mechanics layered on top of the familiar Super Mario Bros. engine: poison mushrooms that shrink Mario rather than power him up, wind currents that push the player unpredictably across levels, backwards warp zones that send players to earlier worlds rather than later ones, and level designs that demand near-pixel-perfect jumps and intimate knowledge of enemy placements. The Lost Levels Enhanced on SNES takes this notoriously demanding source material and presents it with the visual and audio polish expected of 16-bit hardware, offering updated sprites, smoother scrolling, and a refined color palette that brings the Mushroom Kingdom environments to life with greater clarity than the original Famicom Disk System version could manage. The SNES version also incorporates the expanded content originally included in Super Mario All-Stars, the 1993 Nintendo compilation cartridge, which bundled remade versions of the first four Super Mario Bros. games. That means players have access not only to the standard eight worlds but also to the additional worlds — Worlds A through D — that were locked behind completing the main game in the original release, dramatically extending the total content available. Controls follow the established Super Mario Bros. template: the B button runs and throws fireballs when powered up, the A button jumps, and jump height is influenced by running speed, making momentum management central to survival. Level structure progresses through the familiar world-and-stage format, with each world containing four stages culminating in a castle. Unlike the original Super Mario Bros., however, the level design here is engineered to subvert player expectations at every turn — platforms are spaced to punish overconfidence, enemies are positioned to punish rote memorization from the first game, and the poison mushroom lurks in item blocks where a Super Mushroom would normally appear. Luigi is available as a selectable character and handles differently from Mario, featuring higher jumps but reduced traction, making him simultaneously more capable in vertical challenges and more treacherous on fast horizontal sections. The game's reception in its era was shaped largely by the context of Super Mario All-Stars: players encountering The Lost Levels for the first time through that compilation were frequently stunned by the contrast between its difficulty and the relatively approachable remakes of the original Super Mario Bros. and Super Mario Bros. 3 included alongside it. For many Western players, this was their first exposure to the Japan-only sequel, and the experience cemented its reputation as one of the most demanding entries in the mainline Mario series.

About Super Mario Bros - The Lost Levels Enhanced
Pro tips
- Memorize which item blocks contain poison mushrooms in early worlds — they look identical to normal blocks until struck, and hitting them accidentally can cost you a power-up at a critical moment.
- Use Luigi if you are comfortable with slippery controls: his superior jump height opens shortcuts and lets you clear wide gaps that require a running start with Mario, but budget extra stopping distance on every landing.
- Avoid backwards warp zones by not entering pipes or taking paths you haven't deliberately scouted — several zones send you to an earlier world, erasing significant progress.
- When wind is active, adjust your jump timing by releasing the jump button earlier than normal; the wind pushes Mario mid-arc and can carry him past safe landing spots if you hold A for a full jump.
- In later worlds, treat every mushroom block with suspicion and only strike item blocks when you are already in Super or Fire form, so a poison mushroom merely reverts you rather than killing you outright.

How long does it take to beat Super Mario Bros: The Lost Levels Enhanced?
Completing Worlds 1 through 8 and reaching the credits takes most players familiar with Mario games anywhere from 3 to 6 hours due to the high difficulty and frequent restarts. Unlocking and finishing the bonus Worlds A through D can add several more hours, and a no-death run is a significant long-term challenge.
Is this a good starting point for newcomers to the Mario series?
No. The Lost Levels is designed as a challenge for players who have already mastered the original Super Mario Bros. Newcomers will encounter mechanics specifically engineered to punish habits learned from that game. Starting with Super Mario Bros. or Super Mario Bros. 3 is strongly recommended before attempting this entry.
What are the most common mistakes new players make?
The two most frequent errors are striking item blocks without checking for poison mushrooms and using warp zones without verifying they go forward rather than backward. Players also frequently underestimate wind sections, holding the jump button too long and overshooting platforms.
Is Super Mario Bros: The Lost Levels Enhanced worth playing today?
For players who enjoy precision platforming and want a stiff test of Mario mechanics, yes. The SNES presentation holds up well, the level design is inventive even when punishing, and the bonus worlds provide content beyond the base game. Casual players may find the difficulty discouraging without save-state support.
