Gambling Odds, Data & Reference Tables
Downloadable gambling odds, worked examples and regulatory reference data, with plain-English explanations of what each file means.
Use these pages when you want the numbers behind a gambling claim—not just a summary. Each resource explains the result in plain English first, then shows assumptions, sources and downloadable data where useful.
Start with the question you are trying to answer
The strongest resources here begin with practical questions: How much more does 6:5 blackjack cost? How much does a second roulette zero change expected cost? What does a 1.91/1.91 sportsbook market imply? How much actual wagering can a bonus require?
Featured calculations
Dated market information
Canada Online Gambling Market Snapshot: Ontario & Alberta in 2026 records what the official sources said on a particular date. It is intentionally different from stable casino mathematics.
Downloads are optional
CSV and JSON files sit underneath the explanation for readers, researchers or developers who want to reproduce calculations. You do not need to download anything to understand the page.
How we prevent stale numbers
Read Which Gambling Numbers Stay the Same—and Which Need Rechecking? for the distinction between fixed-rule mathematics and claims that need a current source.
