Brain Test Level 142
Level 142: Turn off the light.
The switch doesn't seem to work, or maybe there isn't one.
Solution
You need to use your physical finger!
Simply place your real-life finger (the one you are using to tap the screen) directly on the light bulb/lamp shown on the screen.
Hold your finger there, covering the light source completely. The light will go out, and you will proceed to the next level.
DIFFICULTY
Medium
PRO TIP
Sometimes, you need to literally block the light source to turn it off.
