Quick tactics for this level

Tip 01

After each correct action, expect the scene to change and introduce a new problem. Do not stop after the first fix.

Tip 02

The colorful cushion patches in Part 3 are small and sit on the floor near the window. Drag both onto the cracked window pane to cover the opening.

Tip 03

Nothing in the room — the mirror, the rug, the girl herself — is interactive except the one new prop introduced for each part.

Step-by-step solution

Part 1 — "They are freezing, help!": drag the firewood logs on the left side into the dark fireplace. Flames appear and the room warms.

Part 2 — "Oh no! There is too much smoke!": black smoke fills the room. Tap or drag the window at the upper-left of the room to open it and vent the smoke outside.

The window breaks or shatters when opened.

Part 3 — "The broken window brings in too much cold!": find the colorful cushion patches on the floor near the window. Drag them onto the cracked window pane to seal it.

The window is patched and the cold stops. The level ends with a checkmark.

Common mistakes

Mistake 01

Tapping the mirror, rug, or girl directly in any part — none of these are interactive props.

Mistake 02

Trying to tap or fan the smoke away in Part 2 instead of opening the window.

Board notes

Layout

Level 4 opens inside a room with a girl sitting on a red rug hugging herself from cold. An unlit fireplace stands on the right wall, cut firewood logs lie to its left, a window is at the upper-left, and a mirror hangs on the wall. The prompt reads "They are freezing, help!"

Goal

Three sequential problems appear in the same room, each triggered by fixing the previous one. First, light the fireplace; second, vent the smoke it creates; third, seal the broken window the venting left behind.

Opening

Part 1 — drag the firewood logs into the dark fireplace. Flames appear and the girl warms up. Part 2 ("Oh no! There is too much smoke!") — black smoke pours from the fireplace; tap or drag the window open to let it out. Part 3 ("The broken window brings in too much cold!") — colorful patches (pink and blue cushion squares) appear on the floor; drag them onto the cracked window to seal it.

Danger Zone

In Part 1, the mirror and rug are visual elements only — they cannot be interacted with. Only the logs do something. In Part 2, waving at the smoke or tapping the fireplace directly does not work; the window is the only vent. In Part 3, the patches are easy to miss because they blend into the floor — look near the window base for the colored squares.

Mechanics

Level 4 is a chain-reaction design. Each solution causes a new problem, and each new problem comes with exactly one new prop. The pattern — introduce a problem, provide one new tool, expect you to connect them — repeats until the room is stable. This is the first chain-reaction level in the game.

Level 4 FAQ

How do I light the fireplace in Brain Test 5 Level 4?

Drag the firewood logs on the left side of the room into the dark fireplace. That starts the fire and warms the freezing girl.

How do I fix the broken window in Brain Test 5 Level 4?

After the window breaks in Part 2, colorful cushion patches appear on the floor near the window. Drag those patches onto the cracked window to seal it and stop the cold.
