How we calculate
House edge is stated as expected casino win divided by total initial money wagered, unless a guide clearly says otherwise. Expected loss is total action multiplied by house edge. Calculators use the inputs you provide and do not attempt to predict short-term outcomes.
Rule variations
Casino games are families of rules, not single products. We label figures as typical, illustrative, or rule-specific. Where possible, guides identify the conditions needed to reach a quoted return.
Sources and review
We prioritize game rules, regulatory materials, manufacturer documentation, established mathematical analysis, and reproducible combinatorial or simulation work. Material updates are reviewed for arithmetic, clarity, and commercial independence.
Rounding and limitations
Displayed percentages may be rounded. Simulations approximate a theoretical model and depend on their assumptions. Neither a theoretical return nor a simulation is a promise about an individual session.
Corrections
If we find a material error, we correct it promptly and update the relevant explanation. Readers may contact the editorial team through the About page.
