Player psychology and responsible play

Sophie Kellner writes the articles on this site about what happens to the player rather than in the game: the near-miss effect, chasing losses, the pull of a group — and which measures are actually shown to change behaviour. She summarises published research and treats no one.

About Sophie

Sophie covers the part of gambling that has nothing to do with the mathematics of a game and everything to do with the person playing it.

Her articles describe effects documented in published research — the near miss, the illusion of control, loss chasing, availability — and name what each of them looks like from the inside.

She runs no studies of her own and reports no numbers from conversations with players. Where a figure appears, it belongs to a published source and is attributed to it.

On measures she is deliberately narrow: a deposit limit set before the start, a session length decided in advance, a written log, and a break. Those are the few things with evidence behind them; motivation and technique are not among them.

She is not a therapist and her articles are not treatment. Where a reader recognises a pattern that is costing them more than money, the article points to the help services and self-exclusion tools that exist for it.

She also writes about the social side: chats, streams and groups shape what feels normal, and a group in which long sessions are normal is not support, however friendly it is.

How these articles are made

  • Statements about behaviour rest on published research, attributed wherever a figure is quoted.
  • No studies, surveys or player conversations of our own, and no numbers taken from them.
  • No treatment and no diagnosis: articles on problem gambling point to specialist help services.
“Knowing about an effect does not switch it off. A limit set before you start does.” — Sophie Kellner

Frequently Asked Questions

Who is Sophie Kellner?
An author on this site. She writes about gambling psychology, limits and breaks, and about the communities that form around gambling.

Is she a psychologist or therapist?
No. Her articles summarise published research on gambling behaviour. They are neither treatment nor a diagnosis.

Does she work for the operator?
No. This site reviews the operator from the outside, and she has no access to player data.

What should someone do who recognises a problem?
Set a deposit limit or use self-exclusion straight away, and contact a gambling help service. Her articles list the routes; nothing on a casino site replaces them.

Do mindset and breaks improve the odds?
No. They change decisions — how long someone plays and for how much. The rate of a game is unaffected.
