Strategy guide
- 1.Carefully scan the entire screen for any interactive elements, no matter how small or camouflaged they appear;
- 2.Look for visual inconsistencies - elements that don't match the background pattern or have different shading;
- 3.Try interacting with every element systematically, including tapping, dragging, and holding on different areas.
Common mistakes
- 1.Tapping the obvious large button repeatedly without noticing the small hidden button elsewhere on screen;
- 2.Overthinking the puzzle by trying complex math or patterns when the solution is simple visual observation;
- 3.Ignoring subtle visual cues like shadows, colors, or tiny interactive elements that differ from the background.
