Strategy guide

1.Look for hidden cubes in the background, especially on the left side of the screen;
2.Visualize the stack in 3D to see cubes stacked behind and on top of each other;
3.Count carefully: 9 cubes in the main stack plus 1 hidden cube equals 10 total.

Common mistakes

1.Counting only the visible cubes as 9, missing the hidden one on the left side;
2.Assuming all cubes are flat 2D squares instead of 3D cubes stacked together;
3.Overlooking the single cube tucked behind the main stack on the left edge.
