Brain Out Level 92

Overview

The prompt says "Catch the rat!" A horizontal pipe runs across the upper part of the board with a valve on top, while below it there is a campfire on the left, a cat in the middle, a loose log on the right, and a small stone at the bottom. The rat is hiding inside the pipe, and you cannot reach it directly. The intended trick is to produce smoke from the log, drive the smoke through the pipe, and block the other opening so the rat is forced out. The cat below then catches it once it appears.

• Difficulty: Hard
• Estimated moves: 3

Step-by-Step Solution

1. Read the prompt and inspect the pipe, fire, log, and stone. The rat cannot be tapped or dragged out of the pipe, so look for a way to force it to emerge.
2. Drag the loose log from the right side over to the campfire on the left. Hold it in the flame until the log catches and begins to smoke.
3. Move the smoking log to one opening of the horizontal pipe so the smoke can drift into the pipe channel. The smoke travels through the hollow pipe toward the other end.
4. Place a finger over the opposite pipe opening to seal it. With that end blocked, the smoke has nowhere to escape except back toward the side where the rat is hiding, pushing it out of the pipe.
5. Watch for the rat to emerge from the open end of the pipe. The cat waiting below catches the rat as soon as it appears, and the success panel confirms the level is cleared.
6. If the rat does not come out, check that the log is actually smoking after being held in the fire, and make sure the second pipe opening is fully covered rather than only partly blocked.

Strategy & Reasoning

This level combines an environmental prop with a body-blocking gesture. The fire and log are not decoration: the log must be ignited to create smoke, and the smoke acts as a stand-in for a poisonous or choking gas that flushes the rat from its hiding place. The pipe has two ends, so one opening feeds the smoke while the other must be sealed to keep pressure inside.

Trying to tap the cat or the stone first accomplishes nothing, and dragging the rat itself is impossible because it stays inside the pipe. The correct chain is to build smoke, introduce it into the pipe, seal the far side, and let the smoke drive the rat toward the waiting cat. Breaking any link in that chain leaves the rat hidden and the level unresolved.

Tips & Common Mistakes

• Do not tap the cat expecting it to climb into the pipe; the cat only acts once the rat is pushed outside.
• Make sure the log is held in the fire long enough to start smoking before you move it to the pipe.
• Cover the second pipe opening with your finger while the smoke travels; an unsealed end lets the smoke drift away without forcing the rat out.
