Step-by-step
The girls are seated together on a train, with bags on the rack overhead. Their poses and faces form a conspicuous group across the middle of the image. Use the leftmost posing girl's head as a landmark, then look just beyond its left outline into the train window.
There is another face in that narrow window area. Compare it with the girls actually sitting in front of the glass. The problem is not the V sign or the luggage arrangement: the image contains an unfamiliar observer where your attention is least likely to linger.
Select that background face rather than the girl's cheek or raised fingers. A small screen can make the two outlines seem connected, so pause the video if necessary and compare the border of the window. Once the target registers, read the answer and wait for the stage-clear result.
Tips
- Use the scene around the target to orient yourself: girls pose for a picture on a train, with luggage above their heads and a window behind their seats.
- The unexpected face is at the left border of the window, partly hidden beside the dark-haired girl. Looking only at the foreground faces misses the stranger behind them.
- Pause the video at the marked selection and compare the exact outline of the unfamiliar face in the train window at the far left behind the posing girl before tapping.
Common mistakes
- Selecting a nearby part of the illustration instead of the unfamiliar face in the train window at the far left behind the posing girl.
- Tapping repeatedly before the answer card or result has finished appearing.
