How these guides are written
Every figure on this site is derived from the stated rules of a game, and the working is printed beside the result.
Derived, not collected
Every probability, expected value and edge published here is computed from the stated rules of the game being described, using elementary probability. Nothing is taken from an operator's figures, a commercial specification or a market report. Where a figure depends on an assumption -- a wheel with 37 pockets, a six-deck shoe, a stated 96 per cent return -- the assumption is written into the same sentence as the result, so a reader can check the arithmetic or substitute their own numbers.
The working is printed
Each guide carries a bordered result box in which the result sits on one line and the arithmetic that produces it sits on the next. This is the only claim to authority the site makes. There is no testing programme behind these pages, no laboratory, and no assessment of anything commercial; there is a calculation, and it is shown.
What this site is not
It is not an operator, a bookmaker, a comparison service or a directory. It names no gambling company, rates nothing, links to no offer, and carries no promotional material of any kind. It certifies nothing, despite the domain name. It does not describe how to play any game, does not suggest that gambling is a way to make money -- the arithmetic on these pages says the opposite -- and offers no play-money or demonstration games.
| Element | On this site | Why |
|---|---|---|
| Derived probabilities and edges | Yes | computed from stated rules |
| Printed arithmetic beside each result | Yes | so the figure can be checked |
| Named operators, brands or products | No | this is not a comparison service |
| Offers, prices, promotions or links to play | No | nothing here promotes gambling |
| Ratings, testing claims or certification | No | no testing programme stands behind these pages |
| Play-money or demonstration games | No | the subject is the arithmetic, not the play |
Corrections and consistency
Terms are defined once in the glossary and used consistently. Where two guides state the same figure they state it identically, and where a figure depends on a rule variant, the variant is named. Update stamps record when a page last changed.
What this does not tell you
The guides describe long-run averages computed from stated rules. They cannot describe an individual session, and they are not a description of the law or practice in any jurisdiction.
