What it is and how it works
It fills the screen for a few seconds or until the person closes it, which gives it high visibility but also makes it interruptive. It is common in mobile apps and games, where it appears at transitions such as the end of a level.
On mobile websites, Google warns that intrusive interstitials, those covering content as soon as someone arrives, can harm page experience, and advertising best-practice guidelines discourage them in that context. To be acceptable it should appear at transition points, infrequently and with a visible close button.
