SrGuillester (pronounced sānˈyôr, as in the Spanish honorific) is a Spanish player in Geometry Dash. He is well known for beating notorious Extreme Demons such as The Ultimate Phase and Ice Carbon Diablo X. In addition, he has also verified Lunatic Doom Machine by Andromeda and Optagonus, as Andromeda had hacked the level and it was unrated. It is currently rated demon as of now and it can be found on SrGuillester's account.[1] He has also beaten the once seen impossible Demon Red World by SaRy, and verified three levels: the infamous Cosmic Calamity, Carnage Mode by Findexi, and Hatred, an extreme demon by AZuLer4 and himself, currently sitting at #83 on the Official Demon List.

With 144Hz, he did an "extreme demon week," beating Bloodbath, The Flawless, Quest for Perfection, A Bizarre Phantasm, Uprise, Allegiance, and Breakout, beating one Extreme Demon per day.

He verified a slightly nerfed version of the old impossible level The Big Black on February 25, 2018.

As of September 6 2020, SrGuillester has around 199,000 subscribers.


Early Career

SrGuillester joined YouTube on January 26, 2015. About a week later on February 7, 2015, he uploaded his first Geometry Dash video, which showcased a preview of an unnamed level.[2] Over the next few days, he then started completing Easy Demons, including R U I N S (his first Demon on his channel)[3] and Speed of Light.[4] His first actual achievement was the Demon ToE II V2, completed on November 1, 2015.[5]

On February 25, he got 58% on Deadly Clubstep and claimed to have gotten 72% off recording.[6] Two days later on February 27, he uploaded his first level: Robotic Dreams.[7]

On March 9, he reached 100 subscribers on YouTube and beat Ditched Machine, calling it a Hard Demon.[8] A week later on March 16, he previewed Purity and continued easy levels.[9] Shortly afterward, he released Purity on the same day.[10] Just shy of a week later, he achieved 38% on Fairydust, calling it an "Impossible Demon".[11] Later, he uploaded Challenge[12] and released his first countdown video: Top 5 Songs.[13]

On April 12, he beat Deadly Clubstep, his first Insane Demon.[14] Four days later on April 16, he achieved 55% on Stalemate and called it an "Impossible Demon" again.[15] One week later, he beat the Medium Demon The Realistic.[16]

On May 2, he released a trailer of Doom, a collaboration with Deay.[17] One week later on May 9, he did a practice run of Twilight Step v2, which was considered a notoriously difficult demon at that time.[18] Later, he released a preview of Shadows, a remake of Nine Circles.[19] Afterwards, he got 21% on Ice Carbon Diablo X.[20] Later, he released a second preview of Shadows[21] and got 48% on Clubstep Nightmares.[22] Then, he beat Astronaut 13.[23]

In June, he beat Nine Circles (interestingly calling it harder than Astronaut 13).[24] Next, he beat Theory of Insomnia[25] and got 41% on Elite Z, then considered an Impossible Demon.[26] Then on June 11, he achieved 97% on Stalemate and gave up on the level.[27] Afterwards, he previewed a new level called Regret Cave.[28] Soon after, he beat Twilight Step V2 on June 21[29] and rebeat Deadly Clubstep on June 23.[30] Then, he revealed a second preview of Regret Cave.[31] Then on June 25, he got 62% at Alphabet X[32] and then beat it two days later and became the first legitimate victor.[33] He also got 95% on Stereo Demoness.[34]

On July 2, he verified his level Regret Cave.[35] Ten days later, he achieved 40% on Ice Carbon Diablo X and got 68% off recording.[36] He also got 26% on the hardest level ever: Back on Track, a "near-impossible level" that currently has no victor, as it was hacked by the creator RobTop.[37] He released two previews of Unnamed 666: one on July 22[38] and another on July 24,[39] and later got 94% on Windy Landscape.[40] Afterwards, he beat the difficult memory demon Chaotic Hell.[41]

On August 6, he updated Regret Cave.[42] Next, he got a 9 attempt practice run on Ice Carbon Diablo X[43] and later 68% (again),[44] 69%, and 70%.[45] He also beat Clubstep Nightmares three months after his 48% video.[46] Afterwards, he made a video on vault passwords,[47] as well as one on Geometrical Dominator and Deadlocked.[48] He also previewed an unnamed level on August 30.[49]

On September 1, he reached 600 subscribers.[50] Three days later, he got 94% on Lightwave[51] and then beat it the next day.[52] Then on September 6, he achieved 89% on Extreme Chaos[53] and then beat it five days later.[54] Towards the end of November, he released Ultimate Challenge[55] and beat Acropolis,[56] Swing Squad,[57] and Windy Landscape.[58]

In October, he beat Simg Factorial 10[59] and Audio Excursion.[60] Next, SrGuillester released Bangerang on October 7[61] and then beat El Dorado two days later.[62] Then, he got 61% on his first 'Extreme Demon': Crimson Clutter.[63] Then, he exposed SrMaster Dash for hacking and subsequently received some very polarized reception from his viewers.[64] Afterwards around mid-October, he came incredibly close to verifying Pyromaniac by achieving 97% (twice in fact, and over ten fails at the final wave segment).[65] The next day, he previewed a new level that looked quite hard, named 211.[66] Towards the end of October, he beat nerfed Future Demoness[67] and reached 1,000 subscribers on YouTube.

On November 4, he beat Supersonic[68] and then Sharp Minor.[69] Next, he completed Fairydust[70] and MadHouse.[71] The next day, he beat Sequence.[72] Shortly after, he achieved 63% on Cataclysm.[73] Towards the end of November, he beat Phobos when it was free.[74]

On December 7, he completed UltraSonic.[75] Three days later, he released a preview of his level Finale[76] and beat Poltergeist the next day.[77] But his next major achievement would receive a lot of attention and would attract around 120,000 views. For on December 14, he beat Ice Carbon Diablo X.[78]

Middle Career

In December, SrGuillester beat Ice Carbon Diablo X[78] and then he completed the Meltdown levels. He got 71% on Cataclysm[79] and beat Necropolis,[80] Pyromaniac,[81] 8o,[82] and Ice Carbon Zust.[83] He later got 78% on Cataclysm.[84]

On January 6, 2016, he verified a level created by Andromeda and Optagonus and hacked: Lunatic Doom Machine.[1] Two days later, he previewed what was going to be his most popular level: Hatred, a collaboration with Azuler4 (who was going to stick with SrGuillester for a long time). In this level, SrGuillester made the gameplay and Azuler4 decorated it.[85] This was going to redefine all timing demons, as although only about a minute long, it was Bloodbath difficulty. It would later remain as the hardest timing demon until The Hell World, WcropoliX, Black Blizzard, Northernsense and The Hell Origin came by. It was colored black and white and had the soundtrack 'Hate Everything' by Xtrullor, the former ironically being a favorite of memory demons such as DiabolicForce and Horror Hate. The video received about 250,000 views. Afterward, on January 17, SrGuillester beat The Undying by Blaireswip.[86] Towards the end of January, he beat many Demons including Ultraviolet,[87] Obscurum,[88] and Creeper Force.[89] Finally, he verified Magnix by SCPLanst (or Supernight GMD).[90] This was an Ozpectro-styled level said to be harder than the harder-than-The Ultimate Phase level Lezicuv. SCPLanst also made Skrillex Right In, a level that abuses straight fly and has a Viprin-colored remake Right In, which was verified by Satcho.[91]

On February 5, he beat the psychedelic Lit Fuse.[92] Two days later, for his one-year anniversary, he beat Effot.[93] Two days later, he updated Regret Cave to Insane Demon and got 68%.[94] Another two days later on February 19, he beat Lezicuv.[95] Right afterward on February 20, he got one of the stupidest fails on Cataclysm (93%),[96] on par with BlackWolfJake's Athanatos fail (96%).[97] This fail was to haunt TrusTa when he was verifying Yatagarasu. Fortunately, he finally conquered (old) Cataclysm two days later on February 22.[98] Towards the end of February, he also beat Crimson Clutter[99] and Luminum.[100]

On March 3, SrGuillester beat Entwined Room[101] and beat Landect on March 12.[102] Afterward on March 28, he completed (New) Fexty.[103] Then on April 1, he claimed to have "verified" Hatred, though it was actually an April Fools joke.[104]

On April 3, SrGuillester previewed Underground, which is now a Legacy demon and is a collaboration with Keyblade and CSX42Gaming. Both CSX42 and SrGuillester made the gameplay, and Keyblade decorated it.[105] It rivals Falling Up. Then on April 16, he beat Demonic Bass (now a legacy demon).[106] Then on April 20, he started progressing on Red World and achieved 67%.[107] Two days later on April 22, he beat Skrillex Right In.[108] The next day on April 23, he achieved 71% on Red World.[109] Later on April 27, he previewed an old but soon to be very controversial level: 211. This time there was more information. The level was to be decorated by Etzer, it looked harder than Erebus and had a pixel style. The video showed the first drop in the level.[110]

On May 1, SrGuillester completed Forest Temple.[111] Next, on May 11, he reached 10,000 subscribers on YouTube.[112] Five days later on May 16, he uploaded Sleepwalking, which he beat by using a mobile phone (for a visible version) and a computer (copying his exact mobile movements).[113] Almost a week later on May 22, he would have verified Night Terrors if he did not have a stroke of genius (he accidentally added a start position, deleted it, then accidentally saved and exited the level, leaving it unverified).[114] Later on May 31, he completed The Four Elements.[115]

On June 15, SrGuillester completed Desert Temple (and teased 211 at the end of the video).[116] About a week later on June 24, he completed Forbidden Sector.[117] Just two days later on June 26, he achieved a devastating record of 86% on Cosmic Calamity (as well as 78%, 81% three times, and 86% off-camera).[118]

On July 1, he verified the Insane Demon Cosmic Calamity.[119] Three days later on July 4, he verified the Regret Cave update.[120] Much later, on July 22, he uploaded a trailer for Hatred, showcasing the second drop.[121] Three days later on July 25, he completed Ice Cream.[122]

On August 15, SrGuillester verified Underground.[123] Next, on August 24, he beat Theory of Xoanon. [124] Four days later on August 28, he also completed Red World.[125] Right afterward, he started progressing on an old impossible level called SilentFunk. However, there was to be a Blaireswip rebirth of said level.

On September 26, SrGuillester verified SilentFunk (rebirth). It is one of his most popular videos, with almost 300,000 views.[126] Unfortunately, due to RobTop's jump orb fixing, the level is now impossible along with Audio Extraction, Ice Cream, and more levels (though Audio Extraction got updated and reverified by mobile legend Stilluetto).

On October 19, SrGuillester uploaded a Hatred progress video, in which he achieved an 11 attempt practice run. The level looked completely menacing, especially the first ball segment. It is said to be the hardest ball segment and one of the hardest level parts.[127]

On November 11, SrGuillester beat a level that would give him the bulk of attention: Duelo Maestro by Nacho21. The video has about 840,000 views because SrGuillester beat it without a second player.[128] The only players to have done this besides SrGuillester are Nacho21, Dorami and KrmaL.[129] As he got inspired by the unique level, the next video (uploaded on November 17) was to be a preview of a new extreme level: Freedom Dive.[130] This was a two-player level that was to be Yatagarasu length and the next big demon. However, this level was to have horrible consequences for either Hatred or 211 due to SrGuillester's obsession.

Late Career

On December 6, SrGuillester beat Unnerfed Planet Circles.[131] Next, he completed the last dual segment of Freedom Dive. Afterward, on December 18, he began to progress on Red World Rebirth and achieved 70% (on 60Hz).[132] Then he uploaded another video of Freedom Dive, showcasing an orb maze.[133] He seemed to be infatuated with the level, so what was to happen to Hatred and 211? The next two videos sealed their fates.

  1. Hatred: It was verified on December 27.[134]
  2. 211: It was deleted on December 29.[135]

That way, SrGuillester rid himself of two nuisances. However, this was to be short-lived.

On January 10, 2017, SrGuillester completed Red World Rebirth.[136] Now at this point, SrGuillester was moving to Extreme Demons, but his next video, uploaded on January 18, showcased a near-impossible wave segment. It was almost blind and featured many tight spaces. This was a preview of Cimmerian Shade.[137] Afterward, on January 24, he achieved 78% on A Bizarre Phantasm[138] and exposed AetherDark.

On February 4, SrGuillester beat Conical Depression.[139] Then on February 7, he showcased the full layout of Cimmerian Shade.[140] For now, SrGuillester beat (New) Cataclysm on February 11.[141] He also completed DoomsDay, a level that used to be a top 50 Demon but was removed due to hacking, on February 24.[142]

On March 7, SrGuillester completed the memory Demon Mental Torture.[143] Later on March 11, he achieved 29% on Freedom Dive.[144] About a week and a half later, he completed Flat Major, a remake of Nine Circles underrated for its difficulty.[145] Later he got 47% on Freedom Dive, and the video got around 570,000 views.[146] The level was to be decorated by Azuler4 again but this time there was a new addition: Knobbelboy, who would verify Bloodlust, the current #11 Demon, and also become a creating legend through his level God Eater, now known as Astral Divinity. He was partial to rainbows and since Freedom Dive was to be colored rainbow, it makes sense as to why he would decorate.

On April 23, a month after the 47% video, SrGuillester beat The JanuS Miracle.[147] The next day on April 24, he progressed on End of the World by DemonClown and got a record of 61% and a run of 52-100%.[148]

On May 3, SrGuillester had a new hardest demon: Bloodbath. He beat it on 60Hz.[149] Just four days later on May 7, he beat Bizarre Phantasm[150] and Breakout.[151] Then on May 15, he achieved 70% (and 80% without recording) on AfterCataBath.[152] Two days later on May 17, he completed Aftermath,[153] and another two days later on May 19, he completed Novalis.[154] Then he got a new hardest demon again: Black Blizzard.[155] Later on May 24, he beat the original version of End of the World.[156] Finally, on May 26, he verified Volare. The layout was by GaidenHertuny, the host of later level Ocular Miracle, and the decoration was by Keyblade.[157]

On June 5, SrGuillester previewed Happy End,[158] and on June 10, he achieved 94% on Superex's nerfed copy of Silent Club.[159] The next day on June 11, he completed Silent Club,[160] and just two days afterward, he completed the Team N2 level Artificial Ideology.[161] However, later he would be inactive.

In July, SrGuillester returned and beat several Extreme Demons including Heartbeat[162] and verified The Antimatter.[163] Then on July 24, he verified Carnage Mode, said to be one of the best Demons along with Allegiance, Artificial Ascent, and Digital Descent.[164]

On August 2, SrGuillester completed Betrayal of Fate.[165] Three days later on August 5, SrGuillester progressed on Game Over, a collaboration between Pennutoh, Azuler, and himself, and achieved a run of 38-100%.[166] He started beating KrmaL's Demons (Hi[167] and Rearmed[168]). Afterward, on August 31, he completed Totally Legit Level, in which he had quite a reaction when he took the wrong path and subsequently got 98%.[169]

In September, SrGuillester returned to AfterCataBath and achieved 97%. He also beat Falling Up and Valor (while giving bad comments on both demons and Rearmed). Besides this, he completed the Killbot layout and wished to verify Killbot, but he was turned down by Lithifusion and Antares in favor of level savior BoldStep. However, he beat Game Over. Besides this, he beat Deadly Corridor and Angelic Blood, both unknown unrated extreme demons. Finally, he previewed C18H27NO3 or Capsaicin, which also looked incredibly extreme and was red and black (but not hell-themed) Demon.

October: Besides beating various Nine Circles demon levels, SrGuillester beat random demons. He made a video on his layouts.

November: He started doing long ten-minute videos on levels such as Retention. He reached 1,000 demons and agonizingly died at 81% on Yatagarasu. He previewed Ocular Miracle as well. It was actually hosted by Gaiden but SrGuillester was to verify. The level features dual and fast-paced gameplay (it actually is to be the definer of all gameplay demons). Later, Gaiden would upload amazing decoration as well. He also made a second video on his layouts.

December: Guille rebeat Underground in ten minutes. He made a second fail video and got 45% at Unnerfed Silent Club, later to get 44-100. However, later he turned his attention to once-impossible The Big Black by SAILENT, notorious for its nigh impossible second drop. He made a video called 'SrGuillester Rewind 2017'.

2018 Career

Currently his best month: January 2018. He beat Voksius, WcropoliX, Audio Extraction, Hate War, Trapezoid Happiness, Invisible Deadlocked, 8o X, Temple of Destiny, Phobos, Infernal Abyss and Deception Dive.

February: He started a 'Don't play this level' series, in which he gets a bad fail at what he thinks is a bad demon. First 'bad' level was Quantum Processing, which he beat later. He got 99% and 100% at Yatagarasu, which was now his hardest demon. He beat Plasma Pulse III and Photovoltaic, and also 'bad' demon Athanatos. He also beat the old version of an old level he beat: Fexty. Yet again he went back to ACB and got 86 and 97%. He also beat the once-impossible level The Big Black (after nerfing it), although this is widely considered easier than Yatagarasu.

March: SrGuillester ousted himself again by completing a new hardest demon: Erebus. He previewed a level more than a year old: Cimmerian Shade, looking as imposing as ever. Azuler was once again to decorate the level, as he had decorated the majority of serious SrGuillester levels. He previewed a new level called Distortion, which has quirky and odd gameplay. Less than a week before this was written, SrGuillester beat Cosmorush 21.

April: On April Fools' Day, SrGuillester uploaded the layout of a sequel to Hatred called Deathwish. Interestingly, the soundtrack is Carnage, the same one as that of Carnage Mode, the level SrGuillester verified a few months before. He completed the trending hard demon Future Funk by JonathanGD. On April 14, he picked up Delta Interface by Platnuu, a creator known for his upcoming Extreme Demon Orochi. The level is tech-themed and uses the banned song For The Delta by Camellia. Half of it is blue and slow, the other is fast and orange. SrGuillester got 19-80% and 70% on the level before verifying it on April 24. It sits at #58 on the demons list.

May: SrGuillester started beating various insane demons as he wanted to beat all of them. The Insane Demons include Catastrophic and Quantumwave. He previewed his part in Night Rider. It is an upcoming demon by AncientAnubis, the host of Artificial Ascent, and it was teased by KrmaL, one of the biggest players in the game. It features huge names such as Sunix, Riot, Knobbelboy, SrGuillester himself, KrmaL, and most notably, Zobros. On May 17, he achieved a start position run of 75-100% on Ocular Miracle. In the video description, he said that he will nerf it more to make it more enjoyable. He also reassured everyone that they do not want to make the new hardest possible Extreme Demon.[170]

June: SrGuillester beat a lot of insane demon such as Pulsar, Sourcream 2, Castle of Redemption, 10 and Decimation. He wanted to continue his goal of beating all insane demons in GD. He didn't beat any extremes in June.

July: SrGuilester continues his insane demons grind. He also verified a level called Step Aside. He also used Guitar's icon to beat Phobos, mostly to mock him.

August: SrGuillester mostly beat insane demons during August. He also verified a remake of a level called End of the world, originally made by demonclown and verified by Luqualizer. He also beat the former impossible level called Deathsgate, a hacked level by Aurorus. And the next day he would beat AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.

September: He beat a lot of extreme and insane demons such as Frizzantino Vibes, Artificial Dream, Glowy, Es Dilar Nos, The Hell Dignity, Idols, Blade of Justice, Sakupen Hell, and Excessive Compliment. He also claimed to have beaten ATMarbl off cam. Then he beat Silentium Gradas. At the end of September, he made a compilation of his fails on Extreme Demons.

October: He started the month with Spectral Tentation. He also beat Incipient during this month. And he also started a new series called challengester.

November: He beat The Big Black by Zylenox. Then he gave a final preview of his mega-collaboration Ocular Miracle.

December: He beat Another Cataclysm using the secret way. And that's it.

2019 Career

January: He made swift progress on God Eater by Knobbelboy but then he gave up after getting 93%. He also previewed a level called M-A.
