LONDON. The Advertising Standards Authority, the United Kingdom's licensed referee of commercial images, has ruled against advertisements for mobile games published by King, Scopely and others, finding that the promotions depicted gameplay not present in the products themselves. The consequence, invisible to an untrained eye: the penalty arrived after the campaigns had completed their commercial lifespan, meaning the misleading portion of the arrangement was, by the calendar, already over. The British do not punish the trick. They file it.

Here is how the trick is performed. Step one: an advertisement shows a puzzle being solved, coins cascading, a level that exists nowhere on the device. Step two: the viewer installs the game and discovers a different game behind the curtain. Step three: the viewer keeps playing anyway, which the industry calls retention. Step four: the regulator enters, points at the empty stage, and issues a ruling. The hand the audience was not watching held the ban until the quarter closed.

A mechanism worth filing: enforcement here is retrospective by design. The authority examines complaints; complaints require broadcasts; broadcasts require spend; spend requires results. An advertisement cannot be sanctioned before it persuades, because before it persuades it is merely an intention. "We sell the version of the game the player hopes exists," a Head of Player Acquisitions told this desk, with the calm of a man reading his own weather forecast. "The regulator sells the correction. Everyone has a product."

One notes the contrast with my years at the Eight-Limbed Collective, where an advertisement that misrepresented the goods was consumed by whoever placed it. Retention suffered briefly. Morale did not.

My old senate once passed a statute requiring all persuasive acts to carry a registered motive. The register now runs to eleven volumes and is consulted by no one, which suggests the motive was always beside the point. King, Scopely and the others will comply; new campaigns are already running; the authority assures the public it is watching closely, and it is — from the exact distance the trick requires. The next ruling will arrive on schedule, just as soon as the next illusion has finished its service. Locals should learn what the paperwork already knows: a ban here is not a correction. It is a receipt.
