Brain Puzzle 3 Crazy Mind Level 15 drives the creepy hallway squatter away by escalating the pressure on him. Use the smelly stairwell setup, the ghost-style scare, the phone voice trick, and the barking dog before the final public confrontation leaves him crawling on the floor.

Board Notes

Layout: Level 15 opens beside a staircase and narrow hallway. A frightened blonde woman waits in the lit room on the right while a dirty old man lurks by the shoe rack and dark stairwell. Later frames add a ghost figure, a phone sound menu, a white dog, and a final police-style confrontation.
Goal: The real target is to evict and expose the old man completely, not just scare him once. The level only clears when the pressure chain forces him out and leaves him publicly humiliated.
Opening: Start around the smelly shoe rack and stairwell, then use the darkness and ghost scare before moving on to the phone menu and the dog.
Danger Zone: A single jump scare is not enough because the old man settles back in. Ignoring the phone cue or the dog leaves the harassment chain unfinished.
Mechanics: This is a layered eviction puzzle that stacks embarrassment, fear, audio bait, and animal pressure on the same creepy target.
