Super Mario Bros. Speedrun Is Closing In On Perfection

Nearly four decades after Super Mario Bros. first arrived on the Nintendo Entertainment System (NES), a small group of dedicated speedrunners is bringing the game closer than ever to its theoretical limits. The latest world-record Any% run comes within only a handful of frames of a tool-assisted benchmark once thought unreachable by humans. To understand why this is such a big deal, you need to know how speedrunning works, how frames define the pursuit of perfection, and why a 1980s platformer still commands this kind of devotion.

From Childhood Classic to Precision Esport

Super Mario Bros. launched in 1985 and quickly became one of the most influential games of all time. Its simple controls, side-scrolling levels, and hidden secrets shaped platformers for decades. What makes the game uniquely suited to speedrunning is the combination of:

• Tight and predictable physics
• Short levels that reward aggressive play
• Tricks that exploit the game’s underlying code

Over time, players who grew up with the game started asking a deceptively simple question: how fast can it be beaten if everything goes perfectly? That question spawned a speedrunning scene that has documented routes, glitches, and strategies down to individual frames of gameplay.

Understanding Any%, Frames, and TAS Benchmarks

Speedruns are organized into categories, each with its own ruleset. The category at the center of this record chase is Any%.

What Any% Means

In Any%, the goal is straightforward: reach the end credits as fast as possible, using any available glitches or shortcuts allowed under the category rules. For Super Mario Bros., that means:

• Using warp zones to skip entire sets of levels
• Abusing tricks like wall clips and flagpole glitches
• Choosing precise movements over collecting power-ups or coins

Frames: The Smallest Unit of Progress

The NES typically displays 60 frames per second. For speedrunners, that means:

• 1 second ≈ 60 frames
• Cutting 1 frame from a run is shaving about 0.017 seconds

When world records are clustered around the same second, saving even a single frame becomes meaningful. A difference of ten or eleven frames separates a great run from a historic one.

Tool-Assisted Speedruns and Theoretical Perfection

To understand how close humans are to the true limit, speedrunners look at Tool-Assisted Speedruns (TAS). A TAS is created using emulators and tools that allow frame-by-frame input, rewinds, and savestates to craft a run that assumes inhumanly precise timing. TAS runs are often used as an upper bound on what the game engine allows.

For Super Mario Bros. Any%, a leading TAS has long been considered the theoretical perfection bar. It represents a run with optimised movement, perfect tricks, and no wasted frames. Human runners compare their times to this tool-crafted baseline, and the gap has narrowed dramatically over the last decade.

The Race to Close the Frame Gap

Recent years have seen intense competition among top runners, with the record changing hands several times and edging ever closer to the TAS benchmark.

The Modern Era of Super Mario Bros. Records

For a long stretch, a small set of runners dominated the Any% category. They achieved times that hovered just above the theoretical limit, chipping away at fractions of a second through:

• More consistent execution of known tricks
• Improved setups for difficult glitches
• Refined understanding of the game’s physics and subpixel positions

Recently, one runner in particular, known as Niftski, has been at the center of world-record progression, achieving multiple record-breaking runs within a single year. At various points, he has held times that were:

• Within 18 frames of the TAS benchmark
• Then surpassed by another runner closing the gap further
• Only to reclaim the record and push the difference down to roughly 11 frames

Each milestone has triggered renewed debate about how close humans really are to perfection—and whether the final few frames are even realistically attainable without changes in strategy.

How Much Is 11 Frames, Really?

To a casual viewer, 11 frames seems trivial. That tiny sliver of time equates to less than a fifth of a second. However, measured against the entire route, it represents the last remaining difference between an almost flawless human performance and a perfectly orchestrated TAS run.

In practical terms, 11 frames might come from:

• One slightly suboptimal acceleration from rest
• A more conservative approach to a risky clip
• A lost frame in flagpole manipulation or enemy manipulation

At this level, the runner is already performing dozens of near frame-perfect actions in a row. Finding additional savings without increasing the risk of a failed run becomes extraordinarily difficult.

Inside the Run: Techniques Behind Near-Perfect Times

Reaching within a few frames of a TAS-level time is not simply a matter of “running faster.” It demands deep technical knowledge and the ability to turn theory into consistent execution.

Subpixels, Acceleration, and Facing Direction

Under the hood, Super Mario Bros. tracks Mario’s position more precisely than what appears on screen. These hidden fractional units, often referred to as subpixels, affect whether certain clips work or fail. Because of this, an optimal run must account for:

• Exactly when Mario starts and stops running or jumping
• How long certain buttons are held or released
• Subtle quirks of acceleration, such as accelerating slightly faster when initially facing away from the direction of travel

Minor deviations can quietly shift Mario’s subpixel alignment, making later tricks significantly harder or outright impossible.

Warp Zones and Level Skips

Any% routes lean heavily on warp zones to bypass large chunks of the game. Commonly used warps in 1-2 and 4-2 are optimized through setups that manipulate the camera and terrain to access hidden pipes earlier than intended. These techniques rely on:

• Precise jumps to shift the camera horizontally
• Clipping through tiles by landing at frame-perfect windows
• Maintaining full running speed while threading through narrow spaces

A single misstep in these sections forces the runner to either abandon the run or accept a slower route that can’t compete at the world-record level.

Flagpole Glitches and Animation Skips

One of the most iconic time-saving tricks in Super Mario Bros. speedrunning is the flagpole glitch, which allows Mario to bypass most of the usual flag-lowering animation at the end of a level. Done correctly, this can save dozens of frames over the course of a run.

Executing the flagpole glitch requires:

• Arriving at the flagpole with a specific speed and position
• Landing on particular pixels on blocks or the flag base
• Timed button presses spanning only a frame or two

More advanced setups discovered in recent years have squeezed additional frames out of these segments, but they are correspondingly more demanding to perform.

Risk vs. Reward at the Absolute Limit

When you are less than a dozen frames away from a TAS benchmark, every new optimization tends to raise the risk dramatically. Runners must decide which strategies are “marathon safe” for attempts that could lead to a world record and which are too volatile to include consistently.

Some key decisions include:

• Whether to use a faster but unforgiving clip with near frame-perfect timing
• Choosing between two flagpole setups: one slightly slower but more consistent, another faster but near impossible to hit every time
• Accepting certain micro-optimizations only if they don’t disrupt the rest of the route’s subpixel dependencies

How Today’s Records Compare: A Time Breakdown

The evolution of the Any% world record in Super Mario Bros. is a story of diminishing returns. Early runners shaved off seconds at a time. Today, records fall by a few frames. The table below illustrates, in simplified form, how runs have approached the TAS benchmark.

Community Tools, Verification, and Fair Play

Behind every headline-making record is a robust infrastructure of tools, standards, and community practices that keep the competition fair and transparent.

Leaderboards and Rulesets

The central hub for Super Mario Bros. speedrun verification is the community-run leaderboard on Speedrun.com, which lays out rules for timing, hardware, and allowed techniques. Runs must be recorded and submitted for review, ensuring that records are:

• Timed consistently according to the category standards
• Checked for banned modifications or tools
• Reviewed by moderators with deep knowledge of the game

These structures mirror broader best practices in competitive gaming, where standardized rulesets and public leaderboards underpin a shared sense of legitimacy.

Emulators vs. Original Hardware

Debates within the speedrunning community often revolve around the use of emulators compared with original consoles. Each has advantages and trade-offs:

• Original NES hardware: Offers authenticity and avoids certain timing discrepancies, but is more prone to hardware failure and capture difficulties.
• Emulation: Enables high-quality recording and accessibility, but requires strict rules to ensure that timing, lag, and input methods remain fair.

Many categories distinguish between runs performed on original hardware and emulated platforms, or set specific emulator versions and settings to maintain consistency.

Why a 1985 Game Still Inspires Cutting-Edge Play

On the surface, it might seem strange that highly skilled players spend thousands of hours shaving frames off a run in a game as old as Super Mario Bros. But the appeal is multi-layered and continues to draw new participants.

Accessible Yet Deep

Anyone can pick up a controller and understand how to play Super Mario Bros. within minutes. Yet mastering it at a world-record level requires:

• Precise motor skills
• Knowledge of the game engine and physics
• Mental resilience across hundreds or thousands of failed attempts

This combination of accessibility and depth is one reason retro games remain a cornerstone of speedrunning marathons, including events like Games Done Quick, which raise millions for charity while showcasing high-level runs.

Shared Knowledge and Collaborative Discovery

While world records are individual achievements, they rest on a foundation of community-driven discovery. Players share strategies, publish detailed explanations of glitches, and even collaborate on TAS projects to probe the game’s limits. Over time, this collective effort has steadily pushed human performance closer to the theoretical barrier.

Can Humans Ever Match the TAS?

The enduring question around the current state of Super Mario Bros. Any% is whether a human can ever truly match the TAS benchmark, or whether a small residual gap will remain forever.

Arguments That the Limit Is Near

Those who believe we are almost at the ceiling point to:

• The tiny remaining frame gap (on the order of tens of milliseconds)
• The already extreme difficulty of current strats, which demand extended frame-perfect sequences
• The fact that most “easy” optimizations have long since been discovered and implemented

Reasons to Expect Further Breakthroughs

On the other hand, history suggests caution in declaring any record unbeatable. The community has repeatedly uncovered new techniques that were once considered impossible. Future improvements may come from:

• Discoveries of more consistent setups for currently risky tricks
• Deeper understanding of subpixel behavior and enemy manipulation
• Better training methods, such as input practice tools and real-time feedback overlays

Given enough time, perseverance, and innovation, the last few frames might yet fall—whether to incremental refinement or a completely new strategy.

Frequently Asked Questions

What is the difference between a TAS and a regular speedrun?

A Tool-Assisted Speedrun (TAS) is created using emulation tools that allow the player to script inputs on a frame-by-frame basis, using features like savestates and slow motion. It aims to show the absolute limit of what the game engine allows. A regular speedrun, by contrast, is performed in real time by a human, without such tools, and is subject to human reaction speed, consistency, and nerves.

Why do speedrunners care about single frames?

At the top level, multiple runners often tie within the same second. The difference between first and second place can be a handful of frames, so every frame saved is valuable. Since the most obvious optimizations have already been found, progress now happens in these very small increments.

How do communities verify that a world record is legitimate?

Communities use publicly accessible leaderboards with clear rules. Runners must submit video evidence of their runs, and experienced moderators review them to ensure compliance with category rules, check for suspicious behavior, and confirm timing. This process parallels anti-cheating practices used in esports and online competitive games.

Is speedrunning recognized outside of hobby communities?

Speedrunning has increasingly crossed into mainstream awareness through large events like Games Done Quick, which are covered by major outlets and raise substantial funds for charity. While it is still a niche compared with major esports, its blend of nostalgia, skill, and community spirit has given it a durable presence in gaming culture.

Will new versions or remakes of Super Mario Bros. affect these records?

Remakes and ports—such as those included in later Nintendo releases—are usually treated as separate games for leaderboard purposes because they can have different physics, loading times, or glitches. The classic NES version remains the primary battleground for the most competitive Any% records.
