Brain Puzzle 3 Level 105

Overview

Level 105 is a classroom stealth puzzle. The yellow banner reads "Help her avoid being caught dozing off by the teacher." A classroom is shown with an orange-haired girl in pigtails and a red school blazer sitting at her desk, holding one eye and fighting sleep. A black-haired boy sits at the neighboring desk also resting his cheek on his hand. A female teacher in a black suit with a bun and red glasses stands beside the girl holding a book and red pen. At the top of the screen is a teacher awareness bar with a circular portrait of the teacher's face; a green segment shows when the teacher is looking away. The chalkboard behind is covered in anime doodles and physics formulas. Desks hold a blue cow-print coffee cup and a pink pen holder. A blue backpack sits on the floor, a potted plant and bookshelf stand against the wall, and a window shows a bright blue sky. The bottom caption reads "I'm so sleepy, I'm about to fall asleep..."

Step-by-Step Solution

1. Observe the teacher awareness bar. The green segment at the left of the bar shows when the teacher is distracted. You must time your actions so the teacher does not catch you interacting with objects.

1. Open the window. Tap the large window on the right. It swings open, revealing cherry blossoms outside — and a sudden thunderstorm with lightning clouds rolls in. The room darkens.

1. The teacher gets scared of thunder. With the window open, the teacher freezes, grabs her head with both hands, and trembles from head to toe. Her book and red pen fall to the floor. She is now too frightened to watch the class. The bottom caption reads "Why is it thundering? I'm so scared."

1. Let the girl sleep during the distraction. While the teacher is cowering in fear of the thunder, the orange-haired girl can lower her head onto the desk and nap freely. The teacher cannot catch her.

1. Erase the chalkboard. Tap the chalkboard. All the anime doodles and scribbles are wiped clean, leaving a blank green board. This removes the evidence that the girl was drawing instead of paying attention.

1. Open the backpack. Tap the blue backpack on the floor. Its flaps swing open, revealing a gust of wind that blows across the girl's face. The wind keeps her cool and alert when the thunder passes and the teacher recovers.

1. The girl sits back up. By the time the teacher steadies herself and returns to holding her book, the girl is sitting upright at her desk, eyes open. The teacher sees a well-behaved student. The awareness bar fills green and the "Completed" banner appears with confetti.

Strategy & Reasoning

The puzzle logic is "distract the teacher, fix the evidence, then wake the girl before the teacher looks back." The thunderstorm outside is the key distraction — the teacher is ironically more scared than the sleepy student. By opening the window at the right moment (when the awareness bar shows the teacher looking away), you cause a thunderstorm that paralyzes the teacher with fear. During that window of opportunity, the girl gets to nap. The chalkboard must be erased so there is no proof she was doodling. Finally, the open backpack releases a cooling breeze that wakes her up before the teacher resumes watching.

The awareness bar at the top is a timing mechanic: actions must be performed when the teacher is not looking. The boy at the neighboring desk is set dressing — he is not interactive.

Tips & Common Mistakes

• Mistake: letting the girl sleep while the teacher is looking. If the awareness bar is red (teacher facing forward), tapping the girl gets her caught. Wait for the green segment.
• Mistake: forgetting to erase the chalkboard. The anime doodles are evidence. If the board is not cleaned, the teacher notices the mess even if the girl is awake.
• Mistake: not opening the backpack. Without the wind from the backpack, the girl stays asleep when the teacher recovers and gets caught.
