You want to build levels. Honestly, we all do. There is something fundamentally satisfying about placing a hidden block exactly where a friend is going to jump, or crafting a pixel-perfect speedrun that feels impossible until it isn't. But Nintendo's official ecosystem is expensive. Between the cost of a Switch and the game itself, you're looking at a steep entry fee just to play with some sprites. Thankfully, the internet has spent the last decade building alternatives. If you are looking for free Mario Maker games, you aren't just looking for a cheap knockoff; you're looking for a community.
The reality of "free" in the Mario world is complicated. Nintendo is notoriously protective of its intellectual property. You've probably seen the headlines about fan games getting nuked by DMCA takedowns. Yet, despite the legal shadow-boxing, several high-quality projects have survived and even thrived. Some are browser-based. Others are full-blown executable files that require a bit of setup. They all offer that core "maker" experience without the sixty-dollar price tag.
The King of the Fan Scene: Super Mario Bros. X (SMBX)
If you haven't heard of SMBX, you're in for a treat. It's basically the gold standard. Originally created by Andrew "Redigit" Spinks—the same guy who went on to create Terraria—this engine has been around since 2009. It doesn't just let you make Mario levels; it lets you mix assets from Super Mario Bros. 1, 2, 3, and World, plus stuff from The Legend of Zelda and Metroid.
The current version, SMBX2, is a massive community-driven expansion. It uses a scripting language called Lua. This means people have built things in SMBX that Nintendo hasn't even dreamed of putting in an official Mario Maker title. We’re talking full RPG systems, custom power-ups, and complex boss battles with multiple phases. It feels less like a simple level editor and more like a game development kit for people who love 16-bit aesthetics.
The physics are the most important part. If the jump feels "floaty" or "heavy," the whole thing falls apart. SMBX nails the Super Mario World physics almost perfectly. It’s free. It’s deep. It has thousands of episodes (full campaigns) created by players over the last decade. It’s arguably more "complete" than the actual Mario Maker.
Browser-Based Alternatives for Quick Play
Sometimes you don't want to download a 500MB installer. You just want to mess around during a lunch break. This is where browser-based free Mario Maker games come in, though they are a dying breed due to the death of Adobe Flash and Nintendo's aggressive legal team.
Super Mario Flash was the pioneer here. It's old. It’s clunky. But it paved the way. Nowadays, you’re more likely to find HTML5 projects or emulated versions of older fan games. Mario HTML5 projects pop up on sites like GitHub or itch.io frequently. They usually offer a basic tile set—ground, pipes, Goombas—and a simple "play" mode. They lack the online level-sharing infrastructure of the official game, but for a quick creative fix, they do the job.
Keep in mind that these browser versions often suffer from input lag. Playing a precision platformer in a Chrome tab isn't always ideal. You might find yourself missing jumps because your keyboard didn't register the shift key fast enough. It's a trade-off for the convenience of not installing anything.

Levelhead: The Professional Alternative
Okay, technically Levelhead isn't free. It usually costs money. However, it frequently goes on deep sale, and it represents the best "legal" way to get a Mario Maker experience on PC or mobile. Developed by Butterscotch Shenanigans, it features a delivery robot named GR-18.
The reason I mention it here is the community. It has a "Free-to-Play" feel in terms of how much content you get for a tiny investment. The game is built entirely around a social hub where you compete for "trophies" on other people's levels. The building tools are actually more intuitive than Nintendo's. You can automate almost everything. Want a door that only opens when three specific enemies are defeated? In Mario Maker, that requires weird "jank" involving shells and music blocks. In Levelhead, it’s just a simple logic wire.
Why Do People Keep Making These?
It's about the "kaizo" culture. If you aren't familiar, Kaizo refers to ultra-difficult levels that require frame-perfect inputs. While Mario Maker 2 has a huge Kaizo scene, it’s limited by Nintendo's engine. Fan-made free Mario Maker games allow creators to implement "custom sprites" or "glitch tech" that the official games patch out.

Take Super Mario Maker World Engine. This is a fan project specifically designed to look and feel exactly like the official Switch game, but for PC and Android. It’s a bit "underground" for obvious reasons. It includes the 3D World style, the night themes, and even the power-ups like the Super Bell. It’s a testament to how much people want this experience on devices that aren't the Switch.
The Risks and the Reality
Let's be real for a second. Downloading fan games can be a minefield. Because these aren't official products, you won't find them on Steam or the App Store. You have to find them on forums like Mario Central or dedicated Discord servers.
- Always check the source. If a site looks like it’s from 2004 and is covered in "Download Now" banners, run.
- Preservation is key. Projects like Full Screen Mario were deleted from the face of the earth by legal orders. When you find a version you like, keep the installer on a thumb drive.
- Don't expect 4K. Most of these games are built to mimic the NES or SNES. They look great in a retro way, but they won't push your RTX 4090 to its limits.
Actually, the "jank" is part of the charm. There is something incredibly nostalgic about playing a game made by a person in their bedroom who just really, really loves the way Mario jumps. These creators aren't making money; they're making art.

Getting Started Right Now
If you want to start building today, your first stop should be the SMBX2 website. It has the most active community and the most robust toolset. You'll need a Windows PC, though some people have had luck running it on Linux through Wine.
Once you download it, don't try to build a masterpiece immediately. Start small. Put a Goomba in a pit. Make a jump that is just barely possible. The magic of these games isn't in the graphics or the brand name; it's in the loop of create, test, fail, iterate.
Actionable Steps for Aspiring Makers
- Download SMBX2 (Super Mario Bros. X): This is the safest and most feature-rich starting point for any PC user.
- Join the "Mario Central" Forums: This is the hub for technical help and finding "base ROMs" or asset packs for fan projects.
- Search itch.io for "Platformer Maker": Many indie devs release free, open-source level editors that aren't "Mario" by name but use identical mechanics to avoid legal trouble.
- Look into Lunar Magic: If you are feeling brave, this is the original tool used to hack Super Mario World ROMs. It’s much harder to use than a modern "maker" game, but it gives you absolute control over the code.
- Check the "SMMWE" (World Engine) Discord: For those specifically wanting the Mario Maker 2 interface on a phone or PC, this community-maintained project is the primary destination.
