You may have sharp eyesight and a strong attention to detail if you can quickly identify the one die in this brainteaser that shows seven spots instead of six. The challenge is already tricky, but the added 11-second time limit makes it even tougher. The illustration is filled with dozens of dice scattered across a purple background. At first glance, they all look the same, with the usual faces numbered from one to six. But hidden among them is a single rogue cube with seven dots. The cluttered arrangement makes it especially difficult to spot, as many dice overlap and their dots blend together, creating visual confusion.
