The arithmetic
The bonus is not the number in the advert
A hundred euros is advertised. A turnover many times larger is required. Between the two sits a calculation worth doing before you deposit — and one that is rarely shown.

The expected cost exceeds the bonus. The full working is in the German edition, Was „35× Umsatz“ tatsächlich bedeutet. An English version of the article is in preparation.
What we publish
Lantern Digest is an email newsletter. Each issue takes one current promotional offer from an online casino or betting operator, finds the clauses that determine its value — wagering multiplier, deadline, game weighting, maximum win, excluded payment methods — and works out what is left. If an offer is poor, the issue says so.
We write in German for readers in Germany, Austria and Switzerland. This English page exists so that the nature of the publication is legible to anyone who needs it.

How we are paid
We are an affiliate partner of the operators we write about. If a reader follows one of our links and registers or deposits, the operator pays us a commission. The newsletter stays free and the terms of an offer do not change because of it.
What the commission does not change is the arithmetic. An offer at 45× wagering with a seven-day deadline is worse than one at 30× with thirty days, regardless of who pays better.
We do not operate any gambling service, accept deposits, or run any games.
