Silent Circles is an impossible 2.0 collaboration level by Cyrillic and Sailent. It is a silent level remake of Nine Circles and one of the most popular impossible levels.

Description

• 0-13%: Silent Circles begins with a tricky half-speed cube section requiring some precise timings and featuring fake spikes.
• 13-22%: Next, it transitions into a double-speed ship sequence with some hard straight-flying, precise timings, and requiring the player to go into a fake block in the middle of the section. This part is generally considered the easiest.
• 22-28%: After a difficult, yet possible cube spam, there are three half-speed frame-perfect jumps and the first wave section.
• 28-45%: The first wave section, at triple speed, begins with a very tight corridor featuring some spikes to make it harder, forcing the player to double-click when going down. Then, there is a one-second mini-wave spam that is very difficult but possible, even without too-high CPS spam. After another very tight corridor, there is a mini-wave section with many sawblades and a gravity change, before a tight normal-sized wave part. The section ends with a micro-click, sometimes necessary during a transition to a mini-wave to prevent it from crashing into the slope above. However, it can be avoided by executing a much tighter timing beforehand.
• 45-50%: This part is a 2-player dual with ball and mini-wave requiring precise timings.
• 50-65%: At the infamous 2-player dual wave, the player must do precise spam with two inverted gravity waves. There are three corridors meant for a normal-sized wave, but it uses a mini-wave at half speed. The spam has been beaten by totalgd in the 1-player mode, but it would be much harder or even plain impossible in 2-player.
• 65-100%: The infamous mini-wave spam section; the areas between the spikes have the same pixel length as the mini-wave. Multiple invisible speed changes and blue orbs are within the entire spam corridor. The corridor is imperfectly straight, shifting slightly up and down, so it requires perfectly timed clicks to keep the two mini-waves following it. After that onslaught, there is a hard half-speed mini-wave section with a display of the names of the two creators, 'Cyrillic' and 'Sailent', and then the level ends.

User coins

There is only one user coin, located at 34% in the wave sequence, requiring the player to enter a fake structure and collect the coin that appears.

Theoretical possibility

Despite being one of the most popular levels considered humanly impossible, many players made runs on Silent Circles to prove its possibility. UFokinWotM8 did the first 40% and 27-51%, proving the possibility of the first half, while NcaT proved the possibility of 55-62%. The latter is only possible thanks to a skip found that avoids the dual portal in the second wave section. Even 95-100% was beaten by NcaT (on the link before) and UFokinWotM8.

The current world record is 43.6%, held by PaperGuy as of 20 September 2026.

The infamous spam section is the only part that has not been completed; DraconiaArmy evaluated the CPS required to beat it. For a single wave (not considering the gravity orb), it requires a minimum of about 16 CPS—almost 17 CPS—on normal speed and 32 CPS on double speed. This instance likely makes the level impossible, as of now. Many players believe that using 'drag clicking' or other tricks would allow them to surpass the spam. The current world record utilising drag-clicking (with the orbs) is the 13th spike.

A version of Silent Circles was made for the Impossible Levels List (ILL) that fixed some bugs but, more importantly, nerfed the end spam to 15 CPS. The 15 CPS version of the spam is much easier, making it unlikely but theoretically humanly possible to beat it. The world records by UFokinWotM8 were set on this version, even though they did not reach the spam. However, the ILL eventually increased the CPS cap to 16 CPS for levels, rendering this version insignificant.

Trivia

• Silent Circles contains 14,919 objects, 1,224 of which are colour triggers.
• According to Cyrillic in a comment on a video, Sailent created the first cube and the ship, while he created everything from the orb spam onwards, including the impossible wave.
• Despite being made in Update 2.0 with the pulse trigger being added, the neon effect is still done the pre-2.0 way with two-colour triggers.
  • A single pulse trigger is used during the dual segment between the wave parts to make a few portals dark blue.
• Silent Circles may not have been the one to introduce humanly impossible mini-wave spam parts. A level called Realm of Bloodshadow, released before Bloodbath had wave parts with similar spam.
  • Silent Circles did, however, introduce a more formidable form of an impossible wave. Instead of simply being mainly just spammed in mostly jagged corridors, Silent Circles introduced a wave made to be as hard as possible. This wave is not only mini but also in 2-player mode, requiring the player to control both waves at once. In addition, blue orbs fill the corridor, throwing the player off even further. These same wave parts would later appear in other silent levels, such as Old Slaughterhouse, Slaughter's Hell and Old Pitch Black.
• Silent Circles broke many norms of the Nine Circles levels trend at the time.
  • Silent Circles uses the Geometrical Dominator background instead of the Theory of Everything 2 background and the Deadlocked ground instead of the beveled square ground used in Nine Circles and many other levels like it.
  • The opening cube is at half speed instead of normal speed.
  • Silent Circles is in 2-player mode, meaning during dual sections, both icons can move independently.
  • The slopes in the ship part are made of 1.8 tech slopes rather than 1.9 blocks.
  • The cube and ship parts do not have as many fakes as normal Nine Circles levels.
  • The neon wave is done with only three colour triggers instead of four, and uses the channels 7-3-4 instead of 1-2-3
  • A dual ball/wave part occurs in the middle of the wave part with a 2.0 design, during which the neon effect ceases.
  • There are no 22.5-degree slopes.
  • The structures making up the spam part are not normally found in normal Nine Circles levels.
• Supernova Circles, an easy and nerfed version of Silent Circles, had been rated Demon for less than 10 minutes. After Riot stated that Supernova Circles was hacked, it was immediately unrated a few minutes later, making it one of the quickest levels to get unrated after its rating, alongside Belly Circles by Flozo88, an ocher-coloured level using 'Bionic Belly Button' by Fantomenk as the song: it got featured at just 80 likes, but lost its stars a few minutes later.
• There are strange things hidden outside the boundaries of the screen. These include:
  • Two text objects scaled to 2.00, being an I and a C.
    • Even stranger, the C is three Cs on top of each other.
  • A line of blue 2.0 animated lava objects below, near the start of the wave, below the part with all the sawblades.
  • What appears to be a large wave structure made out of industrial blocks above where the first wave ends, that lacks collision.
  • An invisible wall at the end of the ball dual is likely to prevent the player from skipping the second wave.
    • There is another wall at the end of the level to prevent the player from beating the level without passing the wave. It is unclear why this is here, as it is not possible to reach this wall without cheats.
• ToshDeluxe made an auto version of Silent Circles, and it was rated with 1* until it was unrated due to being an auto copy of a level.
• Sea is known to hate this level slightly for many reasons.
• Although not as popular, a sequel to Silent Circles has been made, being even harder and having a detailed boss fight near the end.
• UFokinWotM8 verified a run on Silent Circles of 27-51% as an extreme challenge called SC2751P.
• starchman is hosting a possible remake of Silent Circles, projected to be Top 5 in difficulty, which is currently being verified by dewbbs.
