Frequently Asked Questions
What does Karin write about?
The German legal framework, budget limits and how to read win announcements.
Why are there no winner stories here?
Because they cannot be verified. What can be verified is the mechanics behind them — how a progressive jackpot is built, for instance.
Are there solid figures for casinos' energy use?
Publicly, hardly any. So none appear in the texts — what is documented is the data use of a video stream.
Which rule has the strongest effect?
The combination of a stake cap and a minimum interval between spins: both bound turnover per hour.
