Why: the goal or problem

Imagine a puzzle game where players finish short levels. A sponsor needs a full-screen message between levels; showing it during play breaks focus, while a permanent banner competes with the controls.

How: work toward a solution

A fictional level puzzle app shows a numbered sequence: level complete, labeled full-screen ad, next level. The closing action is drawn as a label in this static diagram, not a working ad control. No ad is requested and no reward is promised. Timing, revenue and network charges are omitted.

A full-screen ad at a natural transition.

Interstitial ads

Level puzzle app

  1. 1 · Level complete
  2. 2 · Full-screen advertisement

    Close ad → continue

  3. 3 · Next level

Sequence diagram. Close is a label, not a control. No ad request or reward; timing and revenue omitted.

The sequence shows stage completion, a labeled full-screen ad, then the next stage. An advertiser would pay under separate delivery terms; the player receives no reward. The close label is explanatory, not a live ad control.

What: the concept

Interstitial ads cover the app at a natural break, such as completing a level. They interrupt the screen flow, unlike a banner beside content.

Consider interruption costs and distinguish optional rewarded participation.
