Superliminal is easiest to solve when you stop asking how large an object “really” is and start asking what the game can see from your current angle. Almost every blocker is built from that idea: make an object larger by placing it far away, shrink it by placing it close, turn a flat image into a real object by lining it up, or walk through a space that only becomes possible once your perspective changes.
This walkthrough covers the full main route through all nine levels, then gives a practical cleanup plan for collectibles, achievements, Challenge Mode, speedrun attempts, and SomnaSculpt Workshop achievements. It is written for players who want solutions without getting buried in every single collectible coordinate on the first pass. If you are doing a 100 percent run, read the cleanup section before replaying levels so you know what the game saves and what needs special attention.
Core Rules Before The Walkthrough
Keep these rules in mind and most puzzles become readable even before you know the exact answer.
| Rule | How To Use It | Common Mistake |
|---|---|---|
| Perception controls scale | Pick up an object, look far across the room, and release it to make it larger. Release it close to you or near the floor to make it smaller. | Trying to carry the same size object everywhere instead of resizing it for the room. |
| Some doors block objects | Object-blocking doorways let you pass only when your hands are empty. Solve the room from the side where the item is allowed. | Trying to smuggle a cube through a shimmering doorway. |
| Images can become real | If painted or broken pieces align into a cube, pipe, door, or shape, hold the view steady and interact when the image completes. | Walking around randomly instead of finding the exact viewpoint. |
| Objects can be tools, stairs, bridges, or light | Doors, signs, cheese wedges, dice faces, apples, clocks, and even rooms can become platforms. | Thinking an object has only its obvious use. |
| Resetting is normal | If a cloned object, cheese wedge, die, or door gets messy, reset the checkpoint or delete clones where the game allows it. | Trying to rescue a ruined setup for five minutes. |
Fast Route Overview
| Level | Main Idea | What Usually Gets Players Stuck |
|---|---|---|
| 1. Induction | Resize objects, use buttons, and learn object-blocking doors. | Forgetting that the cheese wedge can break the wall panels. |
| 2. Optical | Complete objects from the right viewpoint. | Missing that the moon is an object with a door on it. |
| 3. Cubism | Use dice and dice fragments as stairs, ramps, and route triggers. | Leaving useful dice pieces behind after a cube breaks apart. |
| 4. Blackout | Read darkness as a navigation puzzle, not as danger. | Losing the exit sign light or assuming a dark dead end is real. |
| 5. Clone | Use duplicated objects to build stairs and move buttons indirectly. | Trying to carry cloned apples when the solution is to spawn one in the right place. |
| 6. Dollhouse | Resize rooms, windows, doors, and a bouncy castle. | Making the dollhouse barely enterable instead of truly large. |
| 7. Labyrinth | Trust the dream logic: loops, paintings, holes, arrows, and fake outdoor space. | Stopping too early in elevator and hallway loops. |
| 8. Whitespace | Manipulate the model building, then solve abstract black-and-white space. | Trying to cross the chessboard by pattern instead of using pieces as safe squares. |
| 9. Retrospect | Finish the guided ending sequence. | There is no real puzzle here; keep moving and use the alarm clock. |
Level 1: Induction
Induction teaches the language of the whole game. After the opening contract area, experiment with the table objects until resizing feels natural. The first giant chess piece is a simple lesson: pick it up, aim near the floor, drop it small, then climb past the obstacle.
In the stacked-block room, shrink the upper block, use the fallen chess piece as your first step, and jump out through the door. Soon after, you will meet object-blocking doorways. If a doorway shimmers or stops the object, do not fight it. Put the cube on the pressure button from the allowed side, walk through empty-handed, and solve the next room from there.
The window puzzle is your first remote placement test. Look through the left window to grab the pawn, then place it through the right window onto the button. Use the shadow as your alignment guide. Later, the cheese wedge teaches rotation. Grow it into a ramp when you need height, and in the final puzzle use it as a battering ram: pull the cheese through the wall crack, enlarge it, rotate the point toward the leaning panels, and let it knock the fake wall down.
For 100 percent cleanup, this is also where you can start paying attention to soda cans, fire alarms, fire extinguishers, blueprints, and chess pieces. The main story does not require them, but the game saves collectible progress, so interacting with them early reduces replay work.
Level 2: Optical
Optical shifts from resizing objects to completing them. In the hotel, remove the fire exit door and continue until the room opens up. Pull an exit sign from the wall, make it large enough to climb, and use boxes plus the sign to get over the high wall.
The cube projection rooms are the real lesson. In the first one, stand near the projector and tables until the broken cube image snaps together. Once the cube becomes real, resize it into a step for the high exit. The flower room works the same way, but in two stages: align the flower image to create the next table, then use the new angle to complete the checkered cube. Rotate that cube and it becomes stairs.
Bring the stair-cube into the larger room and climb to the left ledge. From the correct viewpoint, align the missing fire exit door piece on the pillar. When the image completes, interact without moving, then leave through the new doorway. After that, line up the green pipe with the wall stain to create the chess piece and open the path.
The level ends with the moon. Look through the skylight, grab the moon, rotate it until the tiny door is usable, enlarge it, and walk inside. If the door is awkward, keep the moon low enough to enter but large enough that the opening is not just a texture in the sky.
Level 3: Cubism
Cubism is the dice level, but it is less about dice than about accepting broken objects as useful tools. Use the first die as a step into the next room, then combine a large die and a smaller die to reach the high door. When a die leaves a hole behind, drop through and continue through the vent space below.
The sliding-dice room asks you to change floor height rather than carry anything. Lower the middle die, pull the left die across, and use the new arrangement to reach the ledge. When later dice collapse into pieces, do not treat the puzzle as failed. Pick up a die face or chunk, enlarge it, and make a ramp or staircase.
Near the end, remove the dice face opposite the stairs and step into the cube itself. Superliminal often teaches a mechanic literally, then breaks the literal version later. Cubism is the first level where the debris after the “wrong” interaction may be the intended tool.
Level 4: Blackout
Blackout looks like a horror level, but you still cannot solve it by panicking. The opening dark room has a real exit tucked away through the darkness, not at the obvious dead-end door. Move carefully and use small visual cues instead of sprinting.
At the red pit, look down for the narrow path and follow it across. When a door slams behind you, turn around and move backward until the arrow and stair silhouette appear. In the red room blocked by planks, grab the exit sign through the boards, enlarge it, then carry it back through the plastic strips and use it as a portable light. Use it to navigate the boxes, then drop it before the object-blocking door.
The final storeroom gives you a red sign that cannot come with you, so make the sign large enough to illuminate the shelves through the glass. Once you can see the room layout, enter empty-handed, climb the boxes, and reach the high exit. Turn on the IDEA generator and go straight to the elevator.
Level 5: Clone
Clone is where the game stops letting you move every object directly. The first pressure button looks impossible until you remember the door you pulled off its hinges. Carry that door back and place it on the button.
The two fire doors in the Y-shaped corridor are not dead ends. Choose the right-hand door and keep interacting until the smaller copies form a climbable stack. Use the copies like stairs and go over the wall. The alarm clock puzzle expands that idea: clone several clocks, resize them, and build a rough staircase. If the room becomes cluttered, use the game’s clone-clear input and rebuild more cleanly.
The apple puzzles are the most common sticking point. For the first apple, you are not trying to carry the apple off the button. Stand close, clone it, aim high, and drop a large clone onto the original so it gets knocked away. For the next apple puzzle, stand near the target button upstairs and look down at the original apple so only the right part is visible; clone it from that angle so the copy appears on the button.
At the end, clone the SomnaSculpt sign into a staircase. This section rewards messy improvisation, but a few large, stable signs are better than a mountain of tiny copies.
Level 6: Dollhouse
Dollhouse is the point where rooms themselves become objects. Enter the Relaxation Room route, pass through the theater and office space, and reach the dollhouse. Do not make it merely big enough to squeeze into. Make it huge enough that the doorway and window feel like full-scale architecture, then go inside and climb through the interior route.
For the block tower puzzle, enlarge the small fan and aim it at the stacked blocks until the door falls free. The window puzzle is direct: pick up the second window from the left, enlarge it, and walk through once it becomes a real passage.
The bouncy castle/pool section is more finicky. Enlarge the inflatable castle until its door can be used, pass through, then look back through the vent fan and place the castle on the upper diving board. Return through the route that now takes you to that high platform. If you cannot enter the correct door, adjust the castle size a little rather than starting over from scratch.
The two-door keyhole puzzle needs spacing. Place the larger door near the high keyhole door, leaving enough room between the door and wall for you to slip behind it. Place the smaller door on top of the larger one, then enter the larger door and exit from the smaller door onto the high route. The last puzzle looks like a size-restoration problem, but the actual exit is the cardboard dollhouse on the chair. Resize that model on your ledge, enter it, and take the elevator.
Level 7: Labyrinth
Labyrinth is deliberately disorienting, but it still follows rules. At the start, walk through the alarm clock loop until the screen cuts to black and gravity changes. Drop through the shifted doorway into the catering area, use the alarm clock, and return to the bedroom. Take the blue-sky painting, place it at the end of the blank hall like a doorway, and walk into it.
In the sideways red hall, interact with the gray door to expose the exit, then lift the fallen door and drop through the hole underneath. In the orange hall, the painted block is a trap solution: back up while trying to align it, or simply move to the crack near the wall and fall into the next route.
The spiral staircase puzzle works because the staircase breaks the floor. Enlarge it, let it crash through, then climb down to the bottom. Move the slide-like junk near the elevator and enter, but do not assume the level is over. Turn around, leave through the rear door, and follow the exit signs through the repeating hallway.
The pool room uses a die as a perspective elevator. Put it on the left ledge, climb up, then look back so it appears on the upper level and use it again. In the chess-button room, standing on the button lets you see the usable knight through the door; use that knight to hold the button instead of trying to rely on the flattened piece nearby.
The late Labyrinth sequence is a chain of dream transitions. Pick up the die, use it to reach the bed area, drop the cube, walk the long dark corridor, drop again, click the alarm clock among the elevators, and follow arrows through doors until the next clock and elevator. In the fake outdoor area, walk toward each 2D boundary wall until the central bedroom appears, then enter and use the clock.
Level 8: Whitespace
Whitespace starts with a model building. Look at the table model and grab the building piece near the “Jungles” label. Enlarge it until you can enter the door. Once you pass through, the bricked-up exit in the room opens. Shrink the model building, pick it up, and walk toward the door until it pops away. Continue forward through the white space, falling where the path asks you to fall, until you reach the black block. Move the block, pass through the doorway behind it, and later walk through the filing cabinet shadow to continue.
In the white-window room, walk through the window first. When the opposite room is too high, turn around, pick up the now-inverted window cube, and use it as a step. In the next area, go behind the wall with the window, move toward the distant containers and chimney, and flip the switch.
The stairs section is not climbed in the normal way. Walk through the white stair shape, then use the black path that forms. In the looping red-yellow-blue pillar hallway, the white walls are not solid; walk through them and find the door hidden behind the colored end of the structure.
The chessboard is not a safe-tile puzzle. If you step onto the board normally, you fall through. Use the pieces as portable safe spaces: put the light piece on a light square, cross to it, then put the dark piece on a dark square, and repeat until you are across.
The white door and cube puzzle is the strangest one in the main route. Put the cube inside the blank white space behind the 2D door so the door becomes a room. Enter, take the cheese wedge out to the high-door side, enlarge it into a ramp, and climb to the exit. After that, keep dropping through checkerboard holes and corridors. Near the final white expanse, turn around, interact with the black box to reveal an exit sign and red pit, and jump in.
Level 9: Retrospect
Retrospect is the closing sequence. Use the alarm clock, follow the guided route, listen to Dr. Glenn Pierce, and keep moving as the game revisits earlier ideas. There is no hidden final puzzle that requires a special object. Once the sequence ends, you have beaten the story and unlocked the basic completion route.
100 Percent Cleanup Plan
Superliminal’s cleanup is friendlier than it first looks because collectible progress is saved. You can replay levels, collect missing items, and use level select to check progress. Before starting cleanup, open level select and hover levels to inspect icons for categories such as fire alarms, fire extinguishers, constellations, chess pieces, and blueprints. A completed category appears filled; an incomplete one tells you which level still needs work.
| Cleanup Goal | What To Remember | Best Time To Do It |
|---|---|---|
| Fire alarms | They are usually wall-mounted near doors or reception-style spaces. Pull each one once. | During a slow replay of each level. |
| Fire extinguishers | Interact until the extinguisher is fully emptied. Community guides commonly warn that tracking them is harder than alarms. | On the same pass as alarms, checking both sides of every doorway. |
| Sodas | Get each soda type from vending machines. Break one for Sugar Crash, recycle one correctly, and deliberately fail trash once for the trash achievement. | Start in Level 1 and continue through repeated reception rooms. |
| Blueprints | There are 15 blueprint pickups in the community-verified route, mostly in optional ledges, rooftops, vents, and off-path rooms. | After finishing the story, unless you enjoy searching on the first pass. |
| Constellations | Look for hidden constellation rooms and align the stars until the object turns solid or registers. | On a guided collectibles pass, because rooms are easy to miss. |
| Chess pieces | They often require using normal puzzle props in optional ways: reaching vents, ledges, rooftops, and hidden rooms. | After learning the level route, because some pieces are easier with confident resizing. |
Achievement Route Notes
Steam currently lists 27 Superliminal achievements. The table below groups them by how you should approach them, rather than by rarity.
| Achievement Group | Achievements | Practical Notes |
|---|---|---|
| Story and simple actions | Wake Up, Fire Alarmist, Expert Fire Alarmist, Sugar Crash, Please Use Other Door, Son of Man, Why Are You Like This?, Vaguely Activated Achievement | Wake Up comes from beating the story. The others come from ordinary interactions: fire alarms, breaking a soda can, finding the Optical nook, using the apple gag, cloning too many objects, or holding/triggering the early odd achievement condition. |
| Soda and trash | Please Recycle, Take Your Trash Elsewhere, Environment Saved!, Soda Connaisseur | Use vending machines deliberately. Put a soda in the wrong place, fail a trash disposal, place one in the correct recycling bin, and collect all soda varieties. |
| Major collectible sets | Fire Safety Achieved, Fires Extinguished, Stars Align, Feeling Blue, Chess Master | These are the long cleanup achievements. Use level select icons and replay levels until each category is complete. |
| Post-game secrets | Polite Recognition, Kasparov | After all constellations, use the main-menu secret room route for the hidden trophy. After all chess pieces, use the reception computer chess room and make the final move with the rook. |
| Speed and challenge | Speed Runner, Superluminal, Mindful | Know the full route before attempting the under-60 and under-30-minute clears. Challenge Mode scores levels on constraints such as time, grabs, and jumps; finish all challenges for Mindful. |
| Commentary and Workshop | Biggest Fan, Contraband, Dr. Pierce’s Protege, Dream Sculptor, Dream within a Dream | Developer Commentary and SomnaSculpt Workshop are under Extra Modes. Import an object, upload an item, upload a dream, and play another dream for the Workshop set. Use the official SomnaSculpt guide if the upload interface changes. |
For speedrun cleanup, do not start with the 30-minute target. First do a clean no-collectibles story run and memorize the two slowest places: Blackout’s dark route and Labyrinth’s long transition chain. The run is less about risky movement and more about accurate resizing. A failed shortcut usually costs more time than the intended solution.
For Challenge Mode, finish the story first. The mode assumes you already know each puzzle and asks you to reduce waste. If a challenge blocks you, practice the normal version until you can solve it without thinking, then return to the challenge constraints.
