What is a pop up crossword?

A pop-up crossWord is a type of crossWord puzzle that features clues or answers that can be revealed or "popped up" when interacted with, often through a digital format or app. These puzzles may include multimedia elements like audio or visual hints, enhancing the solving experience. Unlike traditional crossWords, pop-up crossWords often offer a more dynamic and engaging way to solve. They can be found in various formats, including online platforms and mobile applications.
