Here’s a puzzle that seems simple at first, but the solution requires looking at the arrangement differently. The challenge is to move just one egg so that there are five eggs on each side. You cannot add or remove any eggs, so everything depends on where you place the single egg you move. Before checking the answer, take a careful look at the rows and consider how the eggs might be counted.

Your first instinct might be to move an egg from one horizontal or vertical row to another. However, those straightforward attempts usually leave one side with too many eggs and the other with too few. The important clue is at the point where the two rows intersect. An egg placed there can effectively belong to both rows, which changes how the arrangement is counted.

Now focus on the single egg at the top. Move it down to the intersection and place it directly on top of the egg that is already there. Nothing has been added or removed; the only change is the position of one egg. With two eggs stacked at the intersection, the horizontal row can be counted as five eggs, while the vertical row also contains five.

That’s the trick behind the puzzle. The stacked eggs at the intersection can be counted as part of both rows, allowing each side to reach five eggs at the same time. The puzzle encourages you to think of the horizontal and vertical lines as completely separate, but the solution comes from recognizing that they can share the same position. Sometimes a simple puzzle becomes difficult simply because you’re looking at it from only one perspective.
