Interstitial Ads
Full-screen ads shown at natural transition points in an app, such as between game levels, that users can close.

Short answer
Interstitial ads are full-screen ads that appear at natural transition points in an app or site, such as between game levels or screens, and can be closed by the user. Their size makes them highly visible with strong engagement. Poorly timed or hard-to-dismiss interstitials frustrate users, and Google penalizes intrusive ones on mobile web.
