About Lea Hartmann
Lea Hartmann writes on this site about the two sides of a bonus offer: the arithmetic to do before accepting it, and the reason the offer looks attractive in the first place.
The arithmetic is always the same and needs no test: bonus amount times wagering multiple gives the volume of play, and volume times house edge gives the expected price. €100 at a multiple of 35 is €3,500 of turnover — at a 4% house edge, €140 expected.
That is why no session logs of her own appear in her pieces. A log nobody can verify is not evidence; the terms of the offer are.
The psychology is descriptive rather than diagnostic: near-miss displays, variable rewards, tiers in loyalty programmes, and what a countdown does to a decision.
It gets practical in one place only: limits set in the account before starting, and the question of whether an offer needs accepting at all — a bonus not taken binds no withdrawal.
She writes for this site independently and is not employed by any operator.
Background & Credentials
- Calculates from the terms an operator publishes, not from test runs
- Names the mechanism behind every psychological effect rather than guessing at one
- No operator accounts, no documented stakes of her own — and no claim that would need them
Once you have worked out the wagering multiple, you no longer need a feeling about the bonus.

Frequently Asked Questions about Lea Hartmann
What does Lea Hartmann write about?
Bonus terms and the mechanisms that make offers attractive — wagering multiple, maximum bet, expiry, tiers in loyalty programmes.
Does she test bonus offers herself?
No. Her pieces calculate from the published terms, because only those are verifiable; a session log of her own would not be evidence.
What are her articles based on?
On operators’ published bonus terms and on published research into reward systems and decision behaviour.
Do her texts help a player win more?
No, and they do not claim to. They show what an offer costs in expectation and which condition binds the withdrawal.
Does she work for an operator?
No. This site is an affiliate publisher and says so openly, but it runs no casino and holds no player data.
