Silent Hill f features a school locker puzzle where players must uncover and use coded combinations to access lockers in the Ebisugaoka Middle School. Suga Yosie's locker, in particular, is locked with a code that looks like a cryptic cry for help "SOS," translated into numbers as 505 using the game's letter-number cipher.
Suga Yosie's locker code and reward

The Suga locker code is 505, formed by converting the letters in "SOS" into numbers: S = 5, O = 0, S = 5. Inside this locker is a school bag that increases the player character Hinako's inventory capacity by 1, which is a helpful upgrade for managing items during gameplay.

The code is hinted at in a note inside Asakura Ayumi's locker, describing the code as a "cry for help".
Understanding the cipher for locker codes
The game uses a cipher commonly referred to as "girl code," where specific letters correspond to numbers: A=4, B=8, E=3, I=1, O=0, S=5, T=7, U=6. Using this cipher helps decode the locker combinations, often reflecting names or words related to the characters. For example, Suga's SOS becomes 505 through this substitution.
How to access the locker puzzle
Players start the locker puzzle by exploring the school to find keys and notes. The notes provide clues to decipher the codes, while keys allow access to new areas including the locker rooms. The puzzle is essential for progression, as some lockers contain keys needed to advance in the game.
