Getting Through the First Chapter
The Laqueus Escape Chapter 1 Walkthrough covers the opening section of the game where you start trapped in what looks like a standard abandoned room. The puzzles are deliberately slow to teach the mechanics. You will spend more time looking at objects than actually solving anything, which is by design. The game wants you to understand how the inventory works before it throws harder combinations at you. Here is how it actually plays out. You wake up bound to a chair. The first thing most people miss is that you need to wiggle your wrists against the chair arms, not just click the bindings repeatedly. The wiggling mechanic is a small back-and-forth motion on your mouse or a repeated tap on mobile. After a few seconds, the rope loosens enough for you to stand up. From there, you have a flashlight, a crowbar, and a locked door. The crowbar goes on the wall right next to where you start. It is not obvious because the wall texture blends with the background. A lot of people miss this because they assume tools spawn from a menu or a chest. They do not. In this game, interactable objects are already placed in the world, but the visual design is intentionally muted to make exploration feel tense. Use the crowbar on the boarded-up vent in the back corner of the room. Once that opens, crawl through into the next area.
The vent leads to a small storage space with a filing cabinet. Inside the cabinet is a keycard, but only after you solve a simple sliding puzzle. The puzzle uses four tiles numbered one through four. You need to arrange them in order. This sounds trivial until you realize the tiles only move when you click a corner piece, and clicking the wrong corner sends the adjacent tiles sliding in unpredictable directions. I spent about twenty minutes on this on my first playthrough because I kept misreading how the grid rotated. The workaround is to click the outer tiles only and treat the center tile as fixed. Do not try to move the middle one. It never helps. After the keycard, you enter a hallway with three doors. The left and right doors are locked and require codes you do not have yet. The middle door opens and drops you into a bathroom. The bathroom has a shower curtain, a sink, and a toilet tank. Look inside the tank first. There is a folded piece of paper with a three-digit code written on it: 7-2-9. This code opens the left door. Do not bother with the right door yet because it needs a second keycard that is hidden inside the left room. The left room contains an office with a computer terminal. The terminal asks for a password. The password is not written anywhere obvious. It is hidden in the wallpaper pattern behind the desk. If you examine the wallpaper closely, certain letters are slightly darker than the rest. They spell out the word "escape," but the terminal requires the password in all caps with a number appended. The number comes from the fire extinguisher mounted on the wall next to the door. The extinguisher has a manufacture date stamped on the bottom: 2019. So the password is ESCAPE2019. The terminal then unlocks the safe inside the desk, and the safe contains the second keycard.
Use the second keycard on the right door. It opens into a stairwell that leads downstairs. This is where Chapter 1 ends and the difficulty ramps up noticeably. The game stops holding your hand after this point. One thing nobody mentions in casual guides is that the flashlight battery drains faster than you would expect if you keep it on while running. I learned this the hard way during a speedrun attempt when I sprinted through the entire hallway with the light active and ended up blind in the next room. Turn the flashlight off between puzzles. It saves roughly forty percent of battery life over a single playthrough, and running out of light mid-puzzle is genuinely frustrating because the game does not pause while your screen is dark. Another counter-intuitive detail is that some objects can be examined in two different states. The locked drawer in the office, for example, looks like a normal drawer until you open the desk cabinet below it. Once you see the empty cabinet, the locked drawer above it becomes interactable with a different set of options. The game expects you to notice this relationship, but it never tells you to look below the desk. I missed it twice. The third time I just started clicking every surface at waist height and lower, which is probably the most reliable approach for anyone stuck.
Get the Full Details

The walkthrough I described here covers the full linear path. There are no alternate routes in Chapter 1, and no missing items that break progression. The only way to get truly stuck is to overlook the wallpaper clue or assume the sliding puzzle works like a standard fifteen-puzzle. Neither assumption is correct. After Chapter 1, the game introduces environmental hazards and timed sequences, so mastering the pacing here matters more than rushing through. If you want to skip ahead or check a specific step, searching for the Laqueus Escape Chapter 1 Walkthrough on any major gaming guide site will give you screenshots for each puzzle. The written path above is accurate, but screenshots help with the visual puzzles because reading about a sliding tile grid is not the same as seeing the exact board state you are dealing with. I would also recommend saving after every solved puzzle. The game auto-saves, but the autosave points are spaced far apart, usually only triggering when you enter a new room. If you die or quit mid-puzzle, you will restart from the last room transition, not from the puzzle itself. That means replaying the crowbar section, the vent crawl, and the bathroom every time something goes wrong. Manual saves cost nothing and take two seconds.
That is it for Chapter 1. The rest of the game gets harder, and the same principles apply: look at everything, check low surfaces, and do not trust the first thing that looks clickable.
