Hollow Knight Silksong Cogwork Core Puzzle Solution Guide
The Cogwork Core puzzle in Hollow Knight Silksong sits at the very top of the Core, just past waves of platforming and sawblade pogo challenges. This section is important because solving the four pillar puzzle unlocks the Architect’s Melody, one of the three melodies needed to reach the end of Act 2. Many players get stuck here, but the solution is clear once you know how the mechanics work.
How to Solve the Cogwork Core Puzzle
At the top of the Cogwork Core you’ll find four tall pillars. Each pillar is divided into four rotating segments. Hitting the levers cycles each segment until its pattern lines up correctly.
Your goal is to align the full design of each pillar so that its pattern forms one clean vertical line. When a pillar is solved it sinks into the floor. Do this with all four pillars to trigger the completion.
Once all pillars are aligned, a pressure plate appears in the center of the room. Step onto it and use your Needolin when prompted. This will unlock the Architect’s Melody, advancing your progress toward the Threefold Melody needed for late-game access.
Puzzle Tips and Strategy
Take one pillar at a time. Focus on the lowest segment and work upward, making sure the design connects before moving on.
If you get lost while rotating, reset by matching any one clear pattern, then align the rest around it.
There is no timer, so you can take as long as you need without penalty.
What You Get for Solving the Puzzle
The Architect’s Melody is your direct reward. This is one of three melodies needed to open the path into the final region of Act 2. It is also a milestone achievement, marking the Cogwork Core as fully explored.
Final Blurb
The Cogwork Core puzzle looks intimidating with its spinning segmented pillars, but the solution is straightforward once you know to align each pillar’s full design. Solving it not only rewards the Architect’s Melody but also clears one of the biggest hurdles in Silksong’s Act 2 progression. Take it slow, align carefully, and enjoy one of the most satisfying moments in the Core.
