Brain Blow Level 47
📝 Walkthrough
Overview
A closed wooden door with a keyhole fills the board, and several keys lie below: a simple yellow key on the left, a paperclip, a butterfly-shaped key, and a safety pin. The prompt asks you to open the door. Only one of the items is a normal key that fits the keyhole, while the other trinkets look decorative or unusable. The simple yellow key is dragged into the keyhole to unlock and open the door.

Step-by-Step Solution
- Inspect the items below the door and identify the simple yellow key among the paperclip, butterfly key, and safety pin. The plain key has the standard teeth and shaft that a lock expects.
- Check the other trinkets and rule them out: the paperclip and safety pin are bent metal objects, and the butterfly-shaped piece is decorative rather than a working key.
- Drag the simple yellow key up to the door's keyhole and insert it into the lock. Align the key with the hole so it seats properly instead of resting against the wood.
- Turn or release the key in the lock to unlock the door. The level completes once the door swings open, and the remaining trinkets stay below unused.
- Line the simple yellow key up with the keyhole before releasing, so the shaft enters the lock instead of resting against the wooden door. Ignore the butterfly piece, which resembles a key at a glance but lacks the standard teeth and shaft the lock expects. Once the key seats in the hole, the door unlocks and swings open; if it stays shut, check that you used the plain key rather than the paperclip, pin, or decorative butterfly.
- The plain yellow key is the only item below the door with a standard key shaft and teeth, which is why it alone fits the keyhole. Once the lock turns and the door opens, the other trinkets remain unused, and the level completes with the door swung aside.
Strategy & Reasoning
Door-lock levels sort usable keys from decorative lookalikes. The keyhole defines what fits, and among the scattered items only the plain yellow key has the shaft and teeth of an ordinary house key. The butterfly piece mimics a key at a glance but does not match the lock, and the paperclip and pin are clearly not keys.
Once the correct key reaches the keyhole, the lock releases and the door opens, which mirrors an ordinary unlocking action. The other objects are there to make the selection less obvious, and choosing any of them fails to turn the lock. The solution therefore combines identifying the real key with dragging it to the door.
Tips & Common Mistakes
- Choose the plain yellow key, not the butterfly-shaped one; only the simple key has the standard shape that fits the lock.
- Drag the key to the keyhole in the door, rather than tapping the door itself, since the lock needs the key inserted first.
- Leave the paperclip and safety pin alone; they are metal trinkets that look like lock tools but do not unlock this door.
