Single zero
There are 37 pockets. A straight-up number wins 1/37 while the 35:1 payout plus returned stake accounts for only 36 units.
The expected loss is one unit per 37 wagered, or about 2.70%, on standard bets.
Double zero
There are 38 pockets, but standard payouts remain unchanged. The two house pockets produce an edge of 2/38, or about 5.26%.
The five-number basket 0-00-1-2-3 pays 6:1 and has a still higher edge of about 7.89%.
Triple zero
Adding a third house symbol creates 39 pockets. Standard 35:1, 2:1, and 1:1 payouts then retain three units per 39 wagered on average, or about 7.69%.
A low table minimum does not compensate mathematically for the higher percentage unless the smaller wager materially reduces total action.
Practical comparison
Compare expected hourly cost using actual wager size, pace, and edge. A $5 single-zero bet can cost less in theory than a $25 double-zero bet despite the better wheel being the main percentage choice.
Electronic and live-dealer interfaces should still disclose the wheel and rules used.
The label is not the specification
For European vs American vs Triple-Zero Roulette, wheel type and special rules such as la partage or en prison determine the price; chip placement does not change the probability.
Check wheel pocket count and any la partage or en prison rule before evaluating a roulette claim; a staking pattern does not change the next spin.
Treat European vs American vs Triple-Zero Roulette as its own rules package. A familiar brand or layout is not enough to import a percentage from another version.
