Analyzing the Smash World Tour settings controversy, its impact on competitive integrity, and lessons for tournament organizers
The Tournament and the Controversial Setting
The conclusion of the prestigious Smash World Tour finals on December 19th, 2021, was overshadowed not by Leonardo ‘MKLeo’ López Pérez’s championship victory, but by a technical discrepancy that threatened the event’s competitive legitimacy. A hidden game mechanic was inadvertently activated, potentially skewing match outcomes during critical bracket stages.
While MKLeo secured his win with an undefeated run, post-tournament scrutiny revealed that a ‘comeback mechanic’ known as Underdog Boost had been active during several matches in the Losers’ bracket, fundamentally changing game physics for affected players.
The Smash World Tour represents the pinnacle of competitive Super Smash Bros. Ultimate, featuring a grueling global circuit where players qualify through regional events. The finals culminate with a Last Chance Qualifier on-site, determining the final contenders who compete for the ultimate title. Every detail, from controller ports to stage lists, is meticulously regulated to ensure fair competition.
The integrity of this carefully constructed environment was compromised when the tournament ruleset was altered. Whether through accidental selection or a procedural oversight, a setting was changed that could have materially influenced the tournament’s trajectory and results.
Analysis confirmed that during streamed matches for Losers Round 3, the “Underdog Boost” feature was enabled. This mechanic, designed for casual play, dynamically adjusts gameplay by giving a player who is behind in stocks (lives) increased damage output and knockback on their attacks. Its activation in a high-stakes tournament setting artificially closes skill gaps by providing a statistical advantage to the losing player, contradicting the core principle of fair competition based solely on player skill.

Evidence, Investigation, and Player Reactions
Melee content creator and technical expert PracticalTAS provided irrefutable, data-driven evidence of the error. His analysis compared specific moves during the affected sets, demonstrating clear numerical deviations. For instance, Ness’s Dash Attack and Mr. Game & Watch’s Forward Throw displayed increased damage percentages consistent with Underdog Boost being active.
Crucially, PracticalTAS’s frame-by-frame review identified that the setting was enabled for the match between Sonix and Maister, but was confirmed disabled during the preceding set featuring MuteAce and Scend. This pinpointed the activation window and suggested the change occurred locally at the stream setup station between those specific matches.
Further complicating the narrative, PracticalTAS noted that within the game’s menu architecture, accidentally enabling a setting like Underdog Boost and saving the ruleset requires more specific, deliberate inputs than simply backing out without saving. This observation fueled community speculation about the error’s origin.
Competitor Maister later corroborated the evidence, recalling an intuitive sense that something was amiss during his match. He acknowledged verifying standard settings like launch rate but admitted he never thought to check for Underdog Boost, as its activation in a tournament environment was considered unthinkable.
Tonight it was brought to our attention from a Twitter user that Underdog Boost was unfortunately active on the stream setup. We are currently investigating, but as of now evidence is pointing to the setting being turned on immediately before Saturday’s final set on VGBC4.

In their official statement, the Smash World Tour administration acknowledged the error: “We believe as of now it was done accidentally while checking the rules. The setting has been corrected, but unfortunately five sets in-total were affected before the error was caught.” Despite this admission, officials decided the tournament would proceed under the existing results, invoking a specific tournament rule to justify their decision.

Rulebook Precedents and Organizer Decisions
The organizers’ decision to continue was grounded in Rule 8.18 of the tournament’s rulebook, which states:
If a game was played under a misconfiguration of the Game Settings that could have materially affected the result of the game, a Player may petition the TO to have that game replayed. The final decision is at the discretion of the TO. This must be done immediately after the game in question; after the next game is started, the previous game shall not be replayed regardless of whether the rules were set correctly.
This rule is designed to prevent bracket delays and infinite regress of protests, but its application here proved inflammatory. Since the error was discovered well after the affected matches and subsequent games had concluded, the window for formal protest had technically closed. The organizers chose the path of least disruption to the schedule, but at a significant cost to perceived fairness.
The players impacted by the glitch expressed profound frustration and a sense of betrayal. Their reactions highlighted the deep personal investment competitors have in these high-stakes events.
They really said “the show must go on” and resumed bracket like nothing happened. Disgraceful

Sonix’s tweet, “They really said ‘the show must go on’ and resumed bracket like nothing happened. Disgraceful,” captured the sentiment of many who felt competitive purity had been sacrificed for spectacle and scheduling.
Can’t help but feel like I wasted my time this weekend cause of the Underdog Boost shit. I basically played a different game during that day and many interactions could’ve been different for both
Regardless, I gotta move on from it, it just hurts for now. 2022 will be different
— LG | Maister (@Maister_SSB) December 20, 2021
Maister’s emotional response was even more poignant: “Can’t help but feel like I wasted my time this weekend… I basically played a different game during that day.” His words underscore how a technical error can invalidate months of preparation and mental fortitude, reducing elite competition to a flawed experiment.
While MKLeo’s dominant victory likely remained unchanged, the controversy cast a permanent shadow over the tournament. For the players in the affected matches, the event is now remembered for its “what ifs” rather than their performances, a lingering doubt that no official ruling can erase.
Lessons Learned and Preventing Future Issues
The Smash World Tour controversy serves as a critical case study in esports event management. Preventing a recurrence requires addressing common pitfalls and implementing robust verification systems.
Common Tournament Setup Pitfalls:
- Over-reliance on Defaults: Assuming a console’s ‘default’ ruleset is correct for competition. Tournament settings should be built from scratch on a clean profile.
- Insufficient Redundancy: Using only one ‘master’ setup for rules. Multiple consoles should have their rulesets independently verified and locked.
- Lack of Pre-Event Player Checks: Not allowing competitors a final opportunity to visually confirm all settings, including obscure ones like Underdog Boost, before their match begins.
Best Practices for Ruleset Verification:
- Implement a Pre-Flight Checklist: Create a physical, step-by-step checklist for station referees to complete before each tournament block, covering every relevant setting.
- Utilize Save-State Locks: Where possible, use the game’s built-in ruleset save/load functions with read-only permissions to prevent mid-event changes.
- Designate a Rules Czar: Appoint a single, responsible official whose sole job is to validate and lock rulesets on all competition stations before play begins.
- Streamline the Protest Process: Revise rules like 8.18 to include clearer provisions for tournament-wide errors discovered after the fact, allowing for discretionary remedies beyond immediate replay.
Building Player Trust After Controversy: Transparency is the only currency that rebuilds credibility. Organizers must go beyond acknowledging mistakes to actively outlining the specific procedural changes implemented to prevent repetition. This includes publishing updated checklists, providing clearer avenues for player feedback on settings, and potentially involving respected community figures in the pre-event verification process. The goal is to shift from a model of assumed correctness to one of demonstrably verified integrity.
Ultimately, the integrity of competitive esports hinges on the perfection of often-overlooked technical details. The Smash World Tour incident is a stark reminder that the battle for fair play is fought not just on the screen, but in the menus and settings that define the competitive space.
