The Dopamine Slot Machine

This episode uses the BrainSafe framework to break down how TikTok’s design drives engagement, focusing on its opaque algorithm, highly personalised “slot machine”-style content feed, lack of natural stopping points, and subtle friction that makes disengaging harder than starting. It argues that while social features play a role, the platform’s core pull is algorithmic, continuously learning what keeps users hooked and delivering it with increasing precision—particularly impacting younger users.

The UK government has finally named the problem — Keir Starmer's crackdown on infinite scroll and autoplay is the most concrete UK action on addictive design we've ever seen. But naming features is whack-a-mole: ban infinite scroll today, and the platforms ship something functionally equivalent under a different name tomorrow.
In this episode, Andrew walks through what the government's getting right, what's missing, and introduces the BrainSafe Standard — a six-dimensional certification framework that asks the structural question rather than the feature-by-feature question. We cover the six dimensions of the BrainSafe Addictive Interface Assessment Framework, share scores from worked assessments of Snapchat, Netflix, Times Tables Rock Stars, and Signal, and explain how businesses can join the 2026 pilot programme.

In the latest episode of The Dopamine Slot Machine, host Andrew interviews Pete Clifford, founder of Karri, about their innovative screen-free messenger device designed for children aged 5-11.
The Karri enables asynchronous voice messaging between kids and parents or approved friends via a 5G network, without apps, scrolling, phone numbers, or stranger access, offering a safer alternative to smartphones.

This week on The Dopamine Slot Machine, Andrew takes a look at Coverstar, an app often marketed as a safer alternative to TikTok for kids.
But how safe is it really?
In this episode we break down how Coverstar works, why short-form video platforms are so addictive by design, and the risks parents should understand before letting their children use it.
We discuss:
• Why removing direct messages does not eliminate stranger interaction
• The reality of children posting public videos online
• Algorithmic feeds, validation loops, and the “dopamine slot machine” effect
• Livestreaming and the risks of broadcasting to strangers
• Practical steps parents can take if their child is already using the app
If your child has mentioned Coverstar or if you are being told it is “TikTok but safe,” this episode will help you understand what is really going on behind the scenes.

You will learn the four needs these games meet for kids, how to replace them with healthier gaming options, and simple steps to transition your child away from addictive platforms without damaging their relationship with games or friends.
