The most useful messages we get point us to something we can check. Write to us about:

• A figure you think is wrong. Tell us the page and, if you can, where your number comes from. Our odds are counted from every possible deal, so we can show you the working.
• A table we have not covered. A studio's Dragon Tiger variant, a casino's rule sheet or a regulator's approval: a link to the published document is all we need.
• A casino listing. Casinos are listed only when their own lobby shows a Dragon Tiger table, and every detail on a card comes from the casino's own pages.
• The tools. Anything the calculator, simulator or predictor does that you did not expect.
