As of early 2026, the latest full build (v2.1 “Dimension Dash”) is available for free download on the project’s official Discord server and Game Jolt page. A Windows version is ready, with Linux and Mac builds in testing.

At its core, the Mario Multiverse Super Fanmade Mario Bros. is not a single game but a hyper-expanded platformer engine. Developed over several years by a loose collective of international programmers, artists, and composers (often under the umbrella of forums like SMW Central or MFGG), this project reimagines Super Mario Bros. as a dimensional hub.
The premise is simple yet explosive: Bowser’s latest scheme doesn’t just kidnap Peach—it shatters the fabric of the Mario multiverse. Portals tear open between Super Mario Bros. 3’s Grass Land, Super Mario 64’s Cool, Cool Mountain, and Super Mario Sunshine’s Bianco Hills. Mario must navigate these fractured realities, often switching between graphical styles and physics engines mid-level.
The keyword here is "Super Fanmade" —meaning the project prioritizes fan service over corporate restraint. Expect obscure enemies from Super Mario Land 2, power-ups abandoned since Super Mario World (we see you, P-Balloon), and even boss rushes against variants of Wart, Tatanga, and Fawful.
For over three decades, Nintendo’s Super Mario Bros. has been a cornerstone of video game design. From the original arcade jump to the open seas of Odyssey, the core formula—run, jump, stomp—remains timeless. Yet, for a certain breed of devoted fan, even Nintendo’s official output has limits. This is where projects like *Mario Multiverse: Super Fanmade Mario Bros. * step in. More than a simple mod or level pack, Mario Multiverse represents a radical, crowdsourced dream: a living, infinite, and interconnected Mario game that the company itself would never dare to make.
A Collision of Eras and Aesthetics
The first striking feature of Mario Multiverse is its visual and mechanical ambition. Unlike official titles, which adhere to a single art style (pixel art for New Super Mario Bros., 3D for Galaxy, hand-drawn for Wonder), fan games like Multiverse often blend them. One level might use the chunky, grid-based tiles of Super Mario Bros. 3, only for a warp pipe to lead into a fully 3D hub inspired by Super Mario 64. Another portal might drop the player into a Super Mario World ghost house rendered with HD lighting. mario multiverse super fanmade mario bros
This is not chaos—it is curation. The “Multiverse” concept acknowledges that every Mario fan has a favorite “universe.” By allowing seamless travel between 8-bit, 16-bit, and modern 3D gameplay within a single session, the game becomes a museum of interactive history. It argues that Mario is not a single timeline but a multiverse of mechanics, each valid and vibrant.
Community as the Core Mechanic
The “Super Fanmade” label is crucial. Mario Multiverse is rarely the product of a single studio; it is an open-source or collaborative platform where level designers, sprite artists, and composers contribute their visions. This leads to a staggering variety of challenges. One level might be a brutal, Kaizo-style precision gauntlet, while the next is a puzzle box requiring you to juggle power-ups from Super Mario Sunshine and Super Mario Galaxy simultaneously.
This community-driven model subverts Nintendo’s carefully controlled difficulty curve. In an official game, the path is designed for mass accessibility. In Mario Multiverse, the difficulty can spike to “masochistic” or drop to “experimental art project.” For many fans, this unpredictability is a feature, not a bug. It transforms Mario from a polished product into a shared language—a meme, a challenge, and a tribute all at once.
What Nintendo Won’t Do
Why does Mario Multiverse matter? Because it fills a void. Nintendo is famously protective of its IP, rarely allowing fan games to exist legally and almost never incorporating fan ideas directly. Consequently, Multiverse can explore ideas that would never pass a corporate quality-assurance test: cross-game power-up combinations (e.g., the Tanooki suit in a Galaxy planetoid), melancholic or horror-themed levels, or meta-narratives that deconstruct Mario’s endless rescue of Peach.
In doing so, the game asks a provocative question: Who owns Mario? Legally, Nintendo does. But culturally, Mario belongs to the millions who grew up with him. Mario Multiverse is an act of affectionate repossession—a statement that the plumber in red is now a folk hero, malleable enough to survive any fan’s imagination. As of early 2026, the latest full build (v2
The Fragile Triumph of Fan Games
Of course, Mario Multiverse lives in a precarious state. Most fan games of this scale exist as downloadable executables, forum threads, or ROM hacks, constantly at risk of a cease-and-desist letter from Nintendo’s legal team. Yet, that very fragility adds to its legend. Playing Mario Multiverse feels like visiting a secret, unauthorized theme park—one that could vanish tomorrow. This impermanence encourages a spirit of preservation and joy that official releases, with their guaranteed availability, rarely inspire.
Conclusion
Mario Multiverse: Super Fanmade Mario Bros. is not a perfect game. It may suffer from uneven level design, obscure progression, or technical glitches. But it is a monument to love. By smashing together every era, style, and mechanic from Mario’s history, it creates a chaotic, beautiful sandbox where nostalgia and innovation collide. In the official games, Mario saves the princess. In the fan-made multiverse, the players save Mario—from becoming predictable, from staying safe, and from ever truly ending. That is a rescue mission worth embarking on.

The most astounding aspect of Mario Multiverse is its technical architecture. Traditional fan games stick to one engine: a SMB1 rom hack, a SM64 mod, or a New Super Mario Bros. fangame. The Multiverse engine, however, is a chimeric beast.
The result is a game that feels less like a level pack and more like a playable museum of Mario’s evolution.
What truly separates Mario Multiverse Super Fanmade Mario Bros. from a simple "greatest hits" collection is its sadistic, clever level design. Because the game assumes you are a veteran, it leverages your nostalgia against you.
Consider the "Glitch Loop Forest." The first screen is a direct replica of Super Mario Bros. World 1-1. You breathe a sigh of relief. But when you hit the invisible block at the end of the level, instead of a vine, a warp zone opens to Lost Levels World 8. That familiar comfort instantly becomes a death trap.
Another standout level is "The 64-Bit Flood." Here, Mario crosses a bridge reminiscent of Super Mario 64’s Bob-omb Battlefield. Halfway across, the bridge dissolves into tile-based blocks from Super Mario Bros. 3, forcing you to switch from analog control to D-pad precision in real-time.
For cooperative play, the game supports up to four players, though the "multiverse" twist often separates them. One player might be solving a 2D platforming section while another is swimming in a 3D underwater labyrinth—they must coordinate to press switches that affect each other’s dimensions.
