A core part of any guessing game is the reveal. It’s not just about showing what’s right or wrong; it’s about building a moment of tension and release. In Sequentle, this meant making the tiles flip over one by one, each with its own suspenseful pause.

Getting this right was a challenge rooted in user experience, not just code. The request wasn't technical—it was emotional. It needed to "feel" right. We used CSS animations to handle the flip itself. The `isRevealing` state in React triggers the animation on the whole row. But the real key was the `animation-delay` property.

By giving each tile in a row a progressively longer delay based on its position (e.g., `position * 300ms`), we created the staggered effect. The first tile flips, then a pause, then the second, and so on. This small detail turns a simple state change into a dramatic moment. It transforms the UI from just showing information to telling a small story with every guess.
