Thirty-seven pockets, one of them green: that is all you need to work out what single zero roulette costs. A straight-up bet pays 35 to 1, which would be fair on 36 pockets; the 37th, the 0, is the house’s share. This page sits under the PH365 live stream tables, and it shows the arithmetic, then sets it beside the double zero wheel.
The single zero roulette wheel in numbers
| Item | Single zero wheel |
|---|---|
| Pockets | 37 (1 to 36, plus 0) |
| Straight-up payout | 35 to 1 |
| Red or black payout | 1 to 1 |
| Chance of red | 18 in 37 |
| House edge | 1 ÷ 37 = 2.70% |
Working out the 2.70%
Take a ₱10 straight-up bet on every one of the 37 numbers, ₱370 in all.
- One number wins and pays 35 to 1: ₱350 plus the ₱10 stake back, ₱360.
- You staked ₱370 and got ₱360 back: a ₱10 loss.
- ₱10 out of ₱370 is 2.70%.
An even-money bet gives the same figure. Red wins 18 times in 37; over 37 spins of ₱10 you expect to win 18 × ₱10 and lose 19 × ₱10, a ₱10 loss on ₱370.
Double zero roulette: one more pocket
The UNLV paper saved on this site works the double zero case: on a 38-pocket wheel, red wins 18 times in 38 and loses 20, so the house advantage is about 5.26%.
| Single zero | Double zero | |
|---|---|---|
| Pockets | 37 | 38 |
| Green pockets | 1 | 2 |
| House edge on most bets | 2.70% | 5.26% |
| Expected cost of ₱1,000 wagered | ₱27 | ₱52.60 |
Same payouts, one extra pocket, almost twice the cost. If a lobby offers both, the single zero table is the cheaper seat.
At a live table
Live roulette streams a real wheel and a real ball; Evolution’s live roulette pages describe single zero tables alongside faster variants such as Speed Roulette and Lightning Roulette, whose extra features change the payouts, so read each table’s payout panel before you bet. The pace is slower than baccarat, but the betting window still closes on a timer, so a freezing stream can cost you a spin; the stream latency fixes help. For a card game whose edge also depends on one table rule, read the blackjack soft 17 explainer.
