Two roulette tables can look almost identical on camera while offering different mathematics. The detail to look for is the green pocket marked 00. It adds another possible result, but a standard winning single-number wager still pays 35 to 1.
For anyone watching a casino influencer explain roulette, the wheel and payout rules provide more useful context than a recent winning streak. Here is what the numbers actually describe.
One zero means 37 pockets; two zeros mean 38
A conventional single-zero wheel has the numbers 1 to 36 plus 0. A conventional double-zero wheel has those same numbered outcomes plus both 0 and 00. New Jersey’s official gaming-equipment rules, section 13:69E-1.7, specify 37 and 38 compartments respectively.
The calculation below assumes a fair wheel, so every pocket has the same probability. It also assumes standard payouts, with no multipliers or special refund rules. Those assumptions matter: a branded roulette variant cannot automatically be analysed as an ordinary wheel.
The difference between 35 to 1 and a 1-in-37 chance
New Jersey’s roulette payout schedule, section 13:69F-5.2, lists a straight-up single-number payout of 35 to 1. That describes the net prize on a winning wager, separate from the return of the original stake. It does not mean there are only 35 possible outcomes.
Consider a purely mathematical one-unit example. On the single-zero wheel, one result wins 35 units and 36 results lose one unit. The expected net result is (35 − 36) ÷ 37 = −1/37, or approximately −2.70% of the amount wagered.
On the double-zero wheel, one result wins 35 units and 37 results lose one unit. The corresponding calculation is (35 − 37) ÷ 38 = −2/38, or approximately −5.26%. These are long-run expectations under the stated rules, not predictions of the next spin or any individual session.
Why red and black are not a complete 50–50 choice
Each conventional wheel has 18 red numbers and 18 black numbers. The green zero pockets sit outside both groups. Red therefore has a probability of 18/37, about 48.65%, on a single-zero wheel, and 18/38, about 47.37%, on a double-zero wheel.
A table may have special treatment for a zero result. For example, New Jersey’s rules permit a half-loss option on specified double-zero even-money wagers. That is why the quoted house edge must identify both the wager and the applicable rules, rather than describe every roulette payout with one percentage.
A history display is a record, not a forecast
Under the independent, fair-spin model, a run of red results does not make black overdue. The next-spin probability still comes from the wheel. Changing the sequence or size of wagers cannot turn those underlying probabilities into a guaranteed profit.
A short video can show a genuine outcome without testing a claimed system. To assess the explanation, ask whether the creator identifies the wheel, shows the relevant payout and distinguishes an observed result from an expected average.
