An ambigram is a word or design that can still be read when you flip it upside down, look at it in a mirror, or rotate it.

Picture writing your name so cleverly that when someone turns the paper upside down, it still reads the same way. That's an ambigram. Some ambigrams are rotational: they look identical when spun 180 degrees. Others are mirror ambigrams: they read the same in a mirror's reflection.

Creating an ambigram requires careful design. Each letter must work double duty, looking like one letter right-side up and transforming into the same (or sometimes a different) letter when flipped. The word “SWIMS” is sometimes used as an example of a rotational ambigram because each letter can be stylized to look like itself upside down.

Artists and designers spend hours crafting custom ambigrams, tweaking curves and angles until the letters work both ways. Some book covers and company logos use ambigrams to create a clever visual surprise. When you spot one in the wild, try flipping it around. The moment you realize what you're seeing is always satisfying, like solving a puzzle hidden in plain sight.
