Compare roulette rules with the assumptions visible
Pocket count, payout and the treatment of zero determine the arithmetic. A game name alone does not specify those rules.

The distinction that matters
For a model with equally likely pockets, calculate net expectation by multiplying each net outcome by its probability. In an ordinary single-number example paying 35 to 1, the winning outcome is plus 35 units and every losing outcome is minus one. With 37 pockets the expectation is (35 − 36) / 37 = −1/37 of the stake; with 38 it is (35 − 37) / 38 = −2/38. These are models of specified rules, not claims about every variant.
A worked example
For illustrative C$100 turnover, the corresponding expected costs are about C$2.70 and C$5.26. Neither is a forecast of a session. A special zero rule or different payout can change the calculation, so the comparison must identify exactly which bet it covers.
Your next steps
- Count the pockets and read the payout schedule.
- State whether the payout includes the stake.
- Check any special rule for zero.
- Compare the same bet type under explicitly stated assumptions.
Where this answer stops
Northline does not confirm which tables an operator offers. The tool cannot model an undocumented multiplier game or certify a wheel. No selection of conventional bets makes a negative expectation into guaranteed income.
