Brain Out 2 Level 10

Overview

Level 10 asks you to "Let him not stay up late and go to bed early!" A boy is tucked in bed at night but is wide awake, staring at a smartphone that is plugged in and charging. The window behind him is completely covered by a closed curtain, the bedroom door is shut, and a pair of scissors lies on the nightstand. Nagging the boy directly does nothing. The solution uses the room itself: first open the curtain to show how late it is, then open the door so his mother walks in to inspect. When the angry mother appears, the boy drops the phone and finally sleeps.

Step-by-Step Solution

1. Notice what is wrong. The boy is lying in bed glued to his phone, which is charging on the nightstand. The curtain is fully drawn, so you cannot tell what time it is.

1. Do not use the scissors on the cable. The scissors on the nightstand look like they are meant to cut the charging wire, but that is a decoy — leaving the phone plugged in is not the answer.

1. Drag the curtain open. Pull the dark curtain to the side so the window is uncovered. Outside it is night: a crescent moon, stars and a city skyline are visible. This shows it is already very late.

1. Open the bedroom door. Tap or pull the closed brown door on the left to open it.

1. Watch mother enter. The door swings open and the boy's mother stands in the doorway holding a feather duster, surrounded by an angry purple aura. The boy gets scared, puts the phone down, and falls asleep with "zzz".

1. Confirm the clear. The prompt reads "No matter how old, I will worry that my mother will come to the room for inspection!" and the green next button appears.

Strategy & Reasoning

The level is about parental enforcement rather than technical tricks. You cannot reason the boy into sleeping by tapping him, and cutting the charger (the obvious gadget solution) does not stop him — he can still play on battery. The joke is that the only thing that ends a kid's late-night phone session is mom's surprise inspection.

The curtain matters because it hides the time. Once you draw it open and see the moon and stars, the scene confirms it is deep at night, but the boy still keeps playing. That shows the curtain alone is not enough — the real trigger is the door. Opening the door brings the mother in, and her angry aura makes the boy finally surrender and sleep.

The reward text drives the theme home: "no matter how old, I will worry that my mother will come to the room for inspection." It is a nostalgic joke about being caught by your mom. The scissors, the phone and the charger are all props; the two required moves are opening the curtain and opening the door.

Tips & Common Mistakes

• Mistake: using the scissors to cut the charger. This looks like the clever solution but is not it. The phone stays plugged in even in the solved scene, so cutting the cable is a wrong turn.
• Mistake: only opening the curtain. Drawing the curtain reveals the moon but the boy keeps playing. You still have to open the door to bring mother in.
• Mistake: tapping the boy or the phone. Tapping him does not make him sleep. Open the curtain, then open the door so the mother's inspection scares him into bed.
