How the content is made
The lessons, guides and practice tools are written and maintained by the people behind CardCount Academy. Counting values, examples and calculations are checked against the code that powers the drills and quizzes, and the practice logic is covered by automated tests. Where a guide makes a factual claim, it lists its sources. Each guide shows the date it was last reviewed.
Our editorial standards
- Numbers come from code or from a named source. The basic strategy chart, card value tables and true count conversions in the guides are generated by the same functions the trainer uses, so an article cannot disagree with the tool. Figures we did not calculate ourselves, such as the effect of a rule on the house edge, are attributed to the source they came from.
- No promises about money. We describe card counting as what it is: a small mathematical edge under specific conditions, with large swings and real limits. We do not publish income claims, "guaranteed" systems or betting tips.
- No casino promotion. We do not review, rank or link to casinos, and we do not accept payment to mention one.
- Corrections are made in the open. When a reader points out an error, we fix the page and update its review date.
If you spot a mistake, please tell us through the contact page — corrections are always welcome.
