The three Basement puzzles
Chapter 2 contains three puzzles that guard the Chapter 2 needle and must be solved in order to free the alien. They are a crystals counting puzzle, a picture rotation puzzle, and a keypad code puzzle with a floor clue. Each puzzle builds on the previous one, and interacting out of order can soft lock the sequence until you reset. Methodical exploration beats trial and error in the dark arena every time.
Community guides describe the same three puzzle types, but the exact numbers and code differ between players and sessions. The structure is confirmed while the answers are per run variables that no guide can hand you. Because the layout is randomized, there is no single correct set of counts to memorize for this challenge. The only universal truth is that you must solve all three to escape the room.
Treat every specific digit or crystal count shared online as a one time observation from another run. The universal code for any given session is pending confirmation until you read your own papers. Guides can teach the method, but they cannot give you the numbers that work today. Solve in your own game and the chapter becomes far less confusing for you.
Crystals counting puzzle
On one side of the secret room you see three crystals on platforms with a zero under each, and clicking a number increases it by one. You count the colored crystals hanging on the walls and ceiling and enter that count under the matching crystal. If you see five red crystals, you click the red platform five times, then repeat for the other colors. The counts reset visually per session, so your numbers will not match a friend's run at all.
Because the layout is randomized, there is no single correct set of counts to memorize for this Search For The Needle puzzle. The puzzle rewards careful observation of your own room rather than memorized numbers from a clip. A methodical circle sweep prevents missing a crystal that hides behind a ledge in the dark. The exact totals are pending confirmation until you observe them in your own game session.
After all three platforms show your counts, the puzzle should register as solved and advance the sequence forward. If it does not, re count each color because a single missed crystal breaks the whole answer. Players who trust a video's totals get stuck because those belong to a different session. Count aloud or note the numbers before clicking to avoid simple input errors that waste time.
Picture rotation puzzle
To the right of the entrance is a large distorted picture made of sixteen pieces, and clicking a piece rotates it once. You rotate every piece until the big picture matches the small reference shown beside it on the wall. A common approach is to complete the outer circle first, then fill in the inner shapes so the design lines up. The target image is visible in the room, so you do not need an external screenshot to finish.
This portion is purely visual and does not depend on randomized numbers, which makes it the most stable challenge. The specific final art may still vary by session, so follow the in game reference rather than a saved image. Clicking pieces in a calm order prevents you from losing track of which ones are already aligned. Take your time and the picture puzzle becomes a relaxing break from the counting.
Unlike the crystals and keypad steps, the picture puzzle cannot be shortcut with a copied answer from anyone. The method is the same for everyone, but the final arrangement is judged by your own reference. If a piece seems stuck, click it again because a double rotation can hide the correct angle. The picture step is reliable once you stop comparing it to other players' screenshots.
Keypad code puzzle
Across from the picture puzzle is a keypad lock that needs a four digit code to open the final step of the room. The code is hidden on papers scattered across the floor of the secret room for you to discover. You flip them until one shows the digits, then type those four digits into the keypad to free the alien. Solving all three removes the lasers blocking the escape door so you can leave.
The keypad answer is generated per session, so a code from a video seen online will not work for your run. The universal code for any given session is pending confirmation until you read your own papers on the floor. Gameplay footage shows players flipping many papers before reaching the one that displays the working code. Patience is part of the step, because decoy papers show an X or other marks instead.
Because the papers are randomized, there is no fixed order to search, but sweeping the whole floor methodically avoids missing the sheet. Keep the keypad in view so you can test a found number immediately without walking away. If a number fails, do not assume the game is broken, because you likely read a decoy or another session's clip. Return to the papers and keep flipping until the correct sheet finally appears.
Strategy and caveats
Interact with everything you can find before trying to solve, because the Basement hides switches and levers that are easy to miss. Inspect walls, floor plates, and corners, then follow the clue trail in the order the room suggests to you. If a puzzle soft locks, reset the room and repeat the sequence calmly rather than forcing random interactions. Keep your upgrades leveled so the arena does not slow your coin flow during the attempt.
The keypad is the third of three Basement puzzles, after the crystals count and the picture rotation step. All three must be solved in order or the sequence can soft lock until a full reset happens. Master the full set rather than only the keypad, because escaping requires all three plus the key from hay. Each numerical answer should be treated as session specific and rechecked live in your game.
Recheck the relevant guide if a walkthrough ever stops matching your session after a patch ships overnight. The per session totals for crystals and keypad remain pending confirmation until you observe them yourself. A guide that promises a fixed code is describing its own run, not a universal constant for everyone. Solve in your own session and the Basement stops feeling impossible to finish.
