During Heather Mason's trek through Brookhaven Hospital in Silent Hill 3, she comes across a door that must be unlocked using a Keypad. The door leads to the second floor patient wing, and must be solved for Heather to progress through the hospital. The keypad consists of buttons numbered from 1 to 9, and the clues to solving the puzzle are found on a nearby stretcher and chalkboard.
The clues and solutions to the puzzle differ depending on which puzzle difficulty is chosen. The process naturally increases in complexity the higher the difficulty level is set, however, the answer is always a four-numbered sequence.
On Easy difficulty, the memo on the stretcher will contain a simple poem. The poem reads:
- "Press, move 2 right;
- press, move up 1;
- press, move 2 down;
- press, the door shall open."
The solution to the puzzle lies in guessing the correct number to start with. According to the first line, the initial button must allow the player to move twice to the right, meaning it is 1, 4, or 7. The second line then instructs to move up once, meaning the initial button must have been either 4 or 7. The third line requires two moves down, meaning the initial button pressed must have been 4.
By starting at four and following the directions exactly, the player is left with the final code of 4639.
On Normal difficulty, the memo with the clue to solving the puzzle is found on a nearby chalkboard; the memo reads:
- "The first is larger than the second;
- the second twice the third;
- the third smaller than the fourth;
- the fourth is half the first.
- Four of the numbers are not repeated
- Three are not in the top row
- Two are not in the right row
- One of the numbers is the final key"
According to the first paragraph, the "fourth is half the first", which means that the first number must be even for the fourth number to be a whole number. Since the first number is double the last, and the highest even number is 8, then the first number is 8, 6, 4, or 2 and the last number is 4, 3, 2 or 1. The line "the third is smaller than the fourth" means the fourth number cannot be 1 and the third number is 3 or lower. The line above reading "the second is twice the third" means the second number is either 6, 4 or 2, and the line "the first is larger than the second" means that first number must be higher than 6. The middle two lines also eliminate 3 and 2 as the last numbers.
Though the directions taken together are confusing, the key is simplifying the clues and the solution can be found using only the first paragraph. The above directions can be simplified as follows:
- first number: 4 or more
- second number: 2, 4 or 6
- third number: 3 or less
- last number: 4
Using the above and simple guess-and-check, the solutions is found to be 8634.
On Hard difficulty, the clue is a sadistic poem written to a lover.
The writer is unknown, as is whether it is a real letter or just a very strange way to remember the code. Given the nearby diary from Stanley Coleman stating that the doctor (the same doctor who sexually abused Christie in the special treatment room where there is a nurse enemy, who may be her) is the one who created the code, the poem is heavily implied to have been written by said doctor, possibly about Christie herself.
- "Pure eyes, blue like a glassy bead —
- You are always looking at me
- and I am always looking at you.
- Ah, you're too meek —
- beautiful, unspoiled:
- thus I'm so sad, I suffer —
- and so happy, it hurts.
- I want to hurt you
- and destroy myself
- What you would think
- if you knew how I felt.
- Would you simply smile,
- not saying a word?
- Even curses from your mouth
- would be as beautiful as pearls.
- I place my left hand on your
- face as though we were to kiss.
- Then I suddenly shove my thumb
- deep into your eyesocket.
- Abruptly, decisively,
- like drilling a hole.
- And what would it feel like?
- Like jelly?
- Trembling with ecstasy, I obscenely
- mix it around and around: I must
- taste the warmth of your blood.
- How would you scream?
- Would you shriek "It hurts!
- It hurts!" as cinnabar-red tears
- stream from your crushed eye?
- You can't know the maddening
- hunger I've felt in the midst of
- our kisses, so many of them
- I've lost count.
- As though drinking in your cries,
- I bring my hopes to fruition:
- biting your tongue, shredding it,
- biting at your lips as if tasting
- your lipstick.
- Oh, what euphoric heights I would
- reach, having my desires fulfilled
- like a greedy, gluttonous cur.
- I longed, too, for your cherry-tinted
- cheeks, tasty enough to bewitch my
- I would surely be healed,
- and would cry like a child.
- And how is your tender ear?
- It brushes against my cheek;
- I want it to creep up to my lips so
- I can sink my teeth into its flesh.
- Your left ear, always hearing words
- whispered sweet as pie —
- I want it to hear my true feelings.
- I never lied, no...
- but I did have my secrets.
- Ah, but what must you think of me?
- Do you hate me? Are you afraid?
- As though inviting you to the agony
- at the play's end, if you wish, you
- could destroy me — I wouldn't care.
- As you wish, you may destroy me
- — I wouldn't care."
The ode, sadistic as it may be, is actually a representation of the correct keys and order that must be pressed. The writer pays particular attention to the victim's face, and when the face is roughly compared to the nine keys, the layout of the keypad becomes:
Following the writer's graphic imagery, the order in which they taste from the person's "face" is the solution to the puzzle. The player must imagine that they are the writer and that the keypad is the victim's face. If part of the face is mentioned but the writer doesn't actually taste from it, simply ignore it.
- The writer places their left hand on the face (the right side of the victim's visage) and digs their thumb into the eye socket, which in this case would be 1. "Cinnabar-red tears stream from your crushed eye" and they say they are "...drinking in your cries". The writer is not tasting from the eye socket, but rather licking tears. In this case, the blood flows down to the number below 1, which is 4.
- The writer says "biting your tongue, shredding it". The tongue is located in the mouth, which in this case is the number 8.
- The writer says "...cheeks, tasty enough to bewitch my tongue", thus the next number must either be 7 or 9.
- They mention the victim's "tender ear" and is then "sinking his teeth" into it. They reveal it was the left ear, which refers to 6.
After putting the clues together, the correct combination will either be 4876 or 4896, and after guessing and checking for the correct third number, the proper sequence is found to be 4896.
