Navigating the mysterious corridors of Mt. Holly in Blue Prince presents players with a intricate web of architectural puzzles, none more captivating than the Clock Tower. Unlocking the secrets hidden within this tall structure demands keen observation, exact timing, and logic deduction. Understanding how to interpret the hidden messages scattered across the grandfather clocks is key to claiming the elusive Sanctum Key rewarded upon completion.
Accessing the Hidden Secret Passage
Before attempting to solve the main riddle, players must first enter the secret room located within the tower. You must position yourself inside the Clock Tower room precisely when the in-game time reaches 1:30 PM. Waiting inside the room until the hands align will trigger a unique cutscene, revealing a hidden passage that grants access to the puzzle area.
Deciphering the Memo Truth Values
Inside the hidden chamber, eight grandfather clocks display individual notes containing rules for the sequence. Deciphering which clues are reliable requires knowledge of the estate's color coding system. As established in other areas of the manor, typewritten blue notes and handwritten red notes state absolute truths, whereas printed red notes are deliberate lies meant to deceive you.
Analyzing the Time Requirements
The core objective requires arranging times that follow all active rules across all eight clocks. The primary constraint dictates that digits 1, 2, 3, and 4 cannot be used, effectively narrowing down potential choices. Furthermore, five specific clocks must terminate exactly on the hour, forming a clear foundation for the remaining times.
The Final Clock Tower Solution
To successfully unlock the compartment, interact with each clock face from left to right to configure the correct times. Set the eight clocks sequentially to 5:00, 5:08, 5:57, 6:00, 7:00, 8:00, 8:05, and 9:00. Inputting this exact sequence satisfies every logical condition and immediately awards you the Sanctum Key.
