Niftski is an American speedrunner who is the fastest person in history to ever complete Super Mario Bros. at 4 minutes, 54 seconds and 631 milliseconds. He also holds other world records for the video game and was the first person to beat it in less than 4 minutes and 55 seconds.
He set his first world record in the any% category for Super Mario Bros. in 2020, with a time of 4:55.430, more than a fifth of a second improvement over Kosmic, the former world record holder. He set the record during a four hour live stream.[4] Justyna Janik notes the practice and study it would take to set this record.[5]
In April 2021, Niftski reclaimed the record from fellow speedrunner Miniland.[6] This time, he brought the time under 4:55, to 4:54.948,[7] a feat that Kyle Orland of Ars Technica compared to the four-minute mile.[6] The 4:55 barrier is expected to be the last "full second" barrier for Super Mario Bros. speedrunning.[6] The community called the milestone "historic".[8]
Orland writes that the video of the run is worth watching to hear Niftski's exclamations. Elizabeth Henges of Eurogamer also notes the emotion shown by Niftski upon reaching the milestone.[9]
After claiming this record, Niftski declared his goal to set world records in other categories, including minus world and blindfolded runs.[6][8]
In late 2021, Niftski reclaimed the world record, again from Miniland. He then improved upon it in August 2022, reducing the time by exactly 5 frames.[10]
In September 2023, Niftski broke his own world record in the game again, lowering the time to 4:54.631. To make this time, he had to add a technique called "Lightning 4-2" to his run, which shaved fractions of a second off that stage of the game. The technique was established by a speedrunner and TASer named HappyLee who used emulation tools (TAS). Niftski himself updated that method, and development of the method used in this run was aided by KingOfJonnyBoy.[11] This record is the first time a human has achieved the best result with respect to "frame rules", however there is still time to save in 8-4, the game's final stage.[12][13]
Orland describes Niftski's video showing a heart rate of 188 BPM, and his tearful reaction following the run, telling himself to "Get oxygen, dude".[11] Dustin Bailey of GamesRadar+ describes Niftski's reaction at the end of the run "a genuine all-timer that really helps sell the significance of the accomplishment."[13]
