Brain Out 2 Level 171

Overview

The screen shows a cartoon apartment block at night. A lovesick boy rests his chin on his hand in the upper-left window, while a girl does the same in the upper-right window, both looking dreamily at each other. On the left windowsill there is a megaphone, a person is asleep behind the middle-right window, a microphone stand stands on the ground, and a green recycling bin sits on the lower right. The prompt asks how to make a sweet call with your lover. The trick is that there is no phone on screen — you must build one out of ordinary objects. The solved frame reveals a "tin can and string" telephone stretched between the two windows, with the subtitle "Encrypted calls".

• Difficulty: Medium
• Estimated moves: 3–4

Step-by-Step Solution

1. Read the scene carefully. The boy and the girl are in two separate windows and cannot reach each other. The megaphone on the sill and the microphone on the ground look like the obvious "loudhailer" tools, but they are distractions.

1. Look at the green recycling bin in the lower-right corner. It is the only place on screen that can contain metal cans. The "sweet call" you need to build is a classic tin-can telephone, so open or drag the recycling bin to get two empty tin cans out of it.

1. Take one tin can and place it at the boy's mouth in the upper-left window. Take the second tin can and place it at the girl's ear in the upper-right window.

1. Connect the two cans with the string that runs between the windows. Once the string is taut, the boy speaks into his can and the sound travels down the string to the girl's can, letting them whisper to each other. The screen shows both characters smiling and the "Encrypted calls" result appears.

Strategy & Reasoning

Brain Out puzzles always hide the answer in an object you would normally ignore. The prompt literally says "call", which makes the brain assume a smartphone or intercom. Because no phone is visible, the intended reading is a homemade communication device. The recycling bin is the deliberate clue: recycling bins hold drink cans, and two cans joined by a taut string make the classic child's "phone". The megaphone and microphone are red herrings that only amplify sound out loud — they do not create a private, "encrypted" conversation between just the two lovers.

Tips & Common Mistakes

• Do not waste time trying to use the megaphone or the standing microphone; they are props, not the answer.
• Do not try to tap the sleeping person; waking him up serves no purpose.
• The cans must be pulled from the green recycling bin, not invented.
• Make sure the string between the two cans is recognized as connected; if only one can is placed, the level will not clear.
