Neither format wins outright. Pre-roll (at game start\/load) is predictable but limited to one slot; mid-roll placed at natural pauses (level end, death, menu return) gets more opportunities and, if spaced correctly, does less damage to retention than an interstitial forced right after another full-screen ad.<\/strong><\/p>\n

Neither format is universally better – it depends on where in the loop you place it. Pre-roll (Google’s adBreak()<\/code> type preroll<\/code> or start<\/code>) runs once, at load or game start, so it’s predictable but you only get that one chance. Mid-roll runs at natural pauses inside the loop – level end, death, returning to a menu (types pause<\/code>, next<\/code>, browse<\/code>) – so it repeats more often across a session, which is usually why it converts more total impressions. Google’s placement rules say ads should only show at natural pauses, never at game start stacked with another full-screen ad, and Google applies a frequency cap automatically, returning frequencyCapped<\/code> in breakStatus<\/code> so you don’t need to hand-roll your own limiter.<\/p>\n

For the serving layer, Playgama Ad<\/a> provides one JavaScript SDK for interstitial (incl. pre-roll), rewarded, banner and in-page video, with AI ad frequency logic that balances revenue and engagement.<\/p>\n

Rewarded ads (type reward<\/code>) sit apart from both: the player opts in, so they convert on intent rather than interruption and tend to protect retention best.<\/p>\n

If no ad is available for a slot, the game should continue immediately rather than block on a blank placement.<\/p>\n

Which should you test first?<\/h2>\n
