Brain Test 5 Level 37

Overview

A loose audio cable and its plug lie on the desk, while a laptop and a pair of headphones sit nearby. The task is to connect that loose cable to the correct device so the audio link is complete and the checkmark appears. The puzzle is a simple matching of plug to port.

• Difficulty: Easy
• Estimated moves: 1

Step-by-Step Solution

1. Identify the loose cable on the desk and trace its plug end, noting which shape or device it belongs to rather than grabbing at random.
2. Look over the available devices: the laptop and the headphones are the two places the cable could connect.
3. Match the plug to its compatible port, lining up the cable end with the socket on the device it belongs to.
4. Connect the plug firmly into that port so the cable is no longer loose on the desk.
5. When the audio link is properly made, the checkmark appears and the level completes.
6. Trace the loose cable from its body to the plug so you know which device the plug belongs to before forcing it toward a socket; matching by shape avoids inserting it into the wrong port.
7. Push the plug in fully until it sits seated in the port; a half-connected cable still reads as loose, and the checkmark waits for the audio link to be made firm.
8. If the link still does not register, trace the cable again to confirm you chose the compatible device; an inserted but mismatched plug will not bring up the checkmark.
9. Make sure the plug reaches the socket without the cable stretching across the desk, since a loose or pulled connection reads as disconnected even after you set the plug down.

Strategy & Reasoning

The level tests plug-and-port matching rather than any repair work. The cable starts disconnected, which is the only fault shown; there is no broken wire or missing part to fix, so the solution is purely routing the plug to the right socket. The two devices in the scene give the choice, and the correct match is determined by what the audio cable is meant to feed in this setup.
The common mistake is reaching for whichever device is closest or most prominent, but the connection only registers on the compatible one. Tapping the laptop or headphones without moving the loose cable also does nothing, because the level checks that the plug itself has been inserted. Once the cable stops lying loose and sits plugged into the device, the setup is complete. This straightforward link-up is what releases the checkmark without further audio adjustment.

Tips & Common Mistakes

• Match the plug to its compatible port; do not force it into the nearest device.
• Actually move the loose cable and plug it in; tapping the laptop or headphones alone will not clear the level.
• Push the plug fully into the socket; a loose or half-seated connection may not register.
