Brain Test 5 Level 4

Overview

"They are freezing, help!" shows a mother kneeling on a pink rug while hugging a swaddled baby, both shivering. A snowy window hangs on the left and an empty gray stone fireplace stands on the right; two damp-looking logs lie on the rug to the left. The solution heats the room with the fireplace, then addresses the smoke and a draft that appear once the fire catches.

• Difficulty: Regular
• Estimated moves: 3

Step-by-Step Solution

1. Identify the fireplace as the only heat source: its opening is dark and empty, while the two logs on the rug are the fuel that belongs inside it.
2. Drag both logs from the rug into the fireplace opening and release them inside the hearth. The wood catches, a flame appears in the fireplace, the mother and baby stop shivering, and the first checkmark appears over her.
3. When the prompt warns "There is too much smoke!", notice the gray smoke filling the chimney area. Let the window on the left act as the vent; its pane cracks open so the smoke can escape instead of building up indoors.
4. When the prompt changes to "The broken window brings in too much cold!", close off the cracked opening with the pink covering so the draft stops. The fireplace keeps burning, the mother and baby remain warm, and the final checkmark appears.
5. Do not drag the mother toward the fireplace; the level checks the fire and the room conditions, not her standing position.

Strategy & Reasoning

The cold problem is solved by combustion: the fireplace is the only object that can produce heat, and the logs are the only fuel in the room. Lighting that fire, however, introduces two follow-up problems the scene stages deliberately. First the smoke has nowhere to go, so a vent has to be opened; after the smoke clears that same opening lets cold air in, so it has to be sealed again. The three actions therefore form a fixed order: supply fuel, vent the smoke, then close the draft.
Alternatives fail because they skip the cause. Dragging the mother closer to the stone does not create warmth while the hearth stays empty. Leaving the logs on the rug keeps the fireplace dark, and the shivering never stops. Once the fire is lit, keeping the window wide open after the smoke clears reintroduces the cold that the fire was meant to fight, which is why the last step covers the opening rather than leaving it aired out.

Tips & Common Mistakes

• Drop the logs inside the dark hearth rectangle, not on the stone surround; wood resting outside the fireplace will not catch.
• Do not move the mother or the baby as the solution; the level measures the fire and the room, not their location.
• Remember to seal the cracked window after the smoke problem passes; an open vent that solved one issue becomes the source of the next cold draft.
