This image looks simple at first—a clean black-and-white design with one large circle and four smaller circles inside it—but it’s actually a visual trick that tests attention to detail rather than math skills.
The trick is that each of the four inner circles contains two smaller circles, often mistaken as a single “8” shape. Many people miss this and undercount.
Carefully counting step by step:
- 1 large outer circle
- 4 medium circles inside
- 8 small circles inside those
So the total is: 1 + 4 + 8 = 13 circles
The puzzle works because the brain quickly groups shapes instead of analyzing them one by one. The correct answer only appears when you slow down and count each circle individually.
Final answer: 13 circles.
