Do not use a standard roulette formula for an unknown variant
A familiar wheel graphic does not establish the payout distribution of a multiplier or special-feature game.
The distinction that matters
The ordinary formula requires known probabilities and net payouts for every relevant outcome. If payouts vary through additional mechanisms, those probabilities and conditions are part of the model. Pocket count alone is insufficient. A name or screenshot cannot supply the missing distribution.
A worked example
A fictional game has 37 pockets but sometimes changes the payout on a selected number. Applying 35-to-1 to every winning event ignores that mechanism. Equally, using the largest advertised multiplier as the normal payout exaggerates return. The full applicable rules are needed before computing an expectation.
Your next steps
- Read the variant's complete payout explanation.
- Identify any separate selection or multiplier probabilities.
- Check stake deductions and feature costs.
- Leave expected return uncalculated when inputs are missing.
Where this answer stops
Northline's standard roulette comparison does not model undocumented variants. An unavailable result is more accurate than a precise percentage built on guessed probabilities. It is not evidence that the game has no mathematical model.
