How To Reach Room 46 in Blue Prince
Your path to Room 46 may run through 40+ rooms, but one you really want to pass through is the Antechamber. When you stumble across the Antechamber, you find all of its gates locked. You need to get past these gates to make it to Room 46, but the contraptions and mechanics seem complex. Therefore, to get to Room 46, we need to unlock the Antechamber gates.

The Western Antechamber Door
The first door we’ll unlock is the Western Antechamber door, which is, well, to the west. To do so, we need to head to the Secret Garden and find the wind vanes. These are close to the center of the garden and atop a pedestal. The vanes have directions marked on them, and to open the gate, we need them pointing west. Use the valves to point the wind vanes in the correct direction and open the door.
Southern Antechamber Door
Head over to the eastern end of the manor exterior to find the Greenhouse. Here, you will find a lever switch that is without a lever. Explore around till you find a broken lever, which you can use to open the gate and access the Antechamber from the southern end. We recommend peeking into the Security Room if you’re struggling to find the Broken Lever.

Eastern Antechamber Door
Head to the Great Hall to find the lever for the eastern gate of the Antechamber. Entering the hall will reveal that all doors are locked, meaning you’ll require keys to progress. If you don’t have any, you can try your luck drafting the Foyer before the Great Hall. Drafting the Foyer will leave all hallway doors unlocked, letting you enter the Great Hall and grab the lever.

Unlock the Northern Antechamber Door and Reach Room 46
The game gives you a hint to unlock the northern door: “To go up, you must go down.” This may seem mind-numbingly puzzling but is easily solved by just glancing at the Basement Key right next to the pedestal. The “down” refers to the Basement, and that’s where we’re headed.
Head to the Underground area using any of its entrances. The doors down there will be locked, but this is where the Basement Key comes into play. Use the key to unlock the doors and explore to find the Rotating Gear Puzzle. Solve and head past the puzzle to find the final lever for the northern Antechamber door. Head back to the Antechamber with all gates unlocked to enter Room 46.
