Strategy guide
- 1.Carefully scan the entire screen for any small or hidden interactive elements, especially near edges;
- 2.Look for size discrepancies between objects - the smallest button is often the correct one;
- 3.Try tapping different areas systematically rather than focusing on the most obvious target.
Common mistakes
- 1.Tapping the obvious large button repeatedly without noticing the small hidden button elsewhere on screen;
- 2.Overlooking the subtle visual clue that indicates the correct button is not the most prominent one;
- 3.Assuming the solution involves complex patterns when it's actually about finding the smallest interactive element.
