A room without a clock

Bill Friedman is an author and former Las Vegas casino manager. He wrote Designing Casinos to Dominate the Competition. His name is attached to a design philosophy of maze-like floors, low ceilings, no windows and no clocks.

The usual explanation is that the casino hides the time to trap its guests. Friedman tells it differently. He has argued that the gamblers asked casinos to lower the blinds and lose the clocks, because they wanted to escape the world outside.

This Journal finds the second account more instructive than the first, and more troubling.

Natasha Dow Schüll, an associate professor at MIT when she spoke to the design program 99% Invisible, described her book Addiction by Design there. The book is about machine gambling. The program said it tracks a shift in the gambling industry away from jackpot play and towards time on device play. Schüll said the most absorbed slot players are looking for a zone in which "a sense of monetary value, time, space, even a sense of self is annihilated." One gambler she quoted said that winning a jackpot frustrated her because it froze her flow. The program summed up the business in one line: this is more about profit from volume. Gamblers want to sit there longer, it explained, and the industry has realized that its profit lies in the volume of play rather than the price of a single play.

The machinery of payment helped. Schüll said that bill acceptors and on-screen credits dematerialized the money and made it feel less real. Player reward cards work like credit cards that the casino sets up for the player. Before them, a player who ran out had to search out a cashier's cage or a roving change attendant.

Read together, these details suggest a system with little need to deceive anyone. Schüll said that the gamblers she met are not dupes and know they are not going to win. The system only has to leave out, one by one, the points at which a person might stop: the clock and the window, which the design philosophy associated with Friedman does without, and the walk to the cashier, which Schüll described the newer payment machinery making unnecessary. The jackpot belongs to a different kind of evidence. Nobody here claims the casino removed it. The player simply wished it away, which shows how much the uninterrupted state was the thing being sought. This Journal reads the casino's real product as the absence of an ending.

A regulator has now described a similar structure. On 6 February 2026, the European Commission announced its preliminary finding that TikTok's addictive design breaches the Digital Services Act. It named four features: infinite scroll, autoplay, push notifications and a highly personalised recommender system. The Commission said that by constantly rewarding users with new content, certain features fuel the urge to keep scrolling and shift the brain into what it called autopilot mode. It added that scientific research shows this may lead to compulsive behaviour and reduce users' self-control.

The Commission said TikTok had disregarded important indicators of compulsive use, among them how much time minors spend on the app at night and how often users open it. These indicators describe patterns of use, which a platform can observe across many sessions. A clock on a wall does a different job. It gives the person in front of it a chance to notice, in the moment, how much time has passed. A casino floor laid out on the philosophy associated with Friedman has no clock to offer the second. The Commission says TikTok disregarded the first. At this stage, the Commission considers that TikTok needs to change the basic design of its service. Its examples include disabling infinite scroll over time and introducing effective screen time breaks. The findings remain preliminary.

The Commission's finding concerns design, not revenue, and it does not describe how TikTok earns money. The parallel this Journal draws is therefore narrower. Both environments are built so that continuing requires no decision and stopping requires one.

It would be easy to treat all this as a story about weak will. Friedman's account resists that reading. If gamblers did ask for the clocks to come down, then the wish to disappear for a while is real, and a design that grants it is simply meeting demand. On the casino floor, in our view, that is the problem. Wanting to lose track of time is ordinary. The trouble is that, by the industry's own logic as the program described it, the casino profits from the volume of play, so the business granting the disappearance gains more the longer it lasts. A business with that incentive can hardly be neutral about when the disappearance ends. This Journal does not carry that economic claim over to the feed, because the Commission did not set out how TikTok earns money. What the two share, on the evidence here, is the missing cue to stop.

This Journal locates personal freedom at that point. Take a person who walks onto a casino floor or opens an app of their own accord. For that person, entering was a decision. The design governs the way out: the moments when a person would normally notice the hour, count the money or sense that something has finished. Remove enough of those moments and choice is never overruled. It is simply never called on.

This Journal's interest in objects and rooms has always been an interest in what they make easy. A printed book has a last page. A meal served in courses lets the table know when it is over. A clock on a wall publicly admits that time is passing. None of these is a moral achievement. Each is a design decision that leaves the choice to stop with the person.

A casino floor laid out on Friedman's principles, and a feed without a last page, make the opposite decision. Whether casinos go without clocks at the gamblers' request, as Friedman has argued, or for the house's benefit, as the usual explanation has it, leaving the clock out is a design decision. On the casino floor, by the industry's own logic as the program described it, the business stands to gain the longer the hour goes unnoticed.
