Ring Thirty-Seven
How it works
The ring
Thirty-seven pockets: the numbers one to thirty-six, plus a single zero. Eighteen of the numbers are lit and eighteen are dark; the zero is neither.
Choosing covers
Tap any pocket to place your stake on it, or use the wide fields underneath for lit, dark, even, odd, the low or high half, a third of the board, or one of the three columns. Several covers can sit on the table at once.
Settling
One pocket is drawn. A single pocket pays thirty-five to one, a third or a column pays two to one, and the wide even fields pay one to one. Everything else on the table is lost.
Rewards
| Outcome | Reward | Chance |
|---|---|---|
| Lit / Dark | 1 : 1 | 18/37 |
| Even / Odd | 1 : 1 | 18/37 |
| Low 1–18 / High 19–36 | 1 : 1 | 18/37 |
| 1st third / 2nd third / 3rd third | 2 : 1 | 12/37 |
| Column A / Column B / Column C | 2 : 1 | 12/37 |
| One pocket | 35 : 1 | 1/37 |
The odds
One pocket of thirty-seven
A single pocket comes up once in thirty-seven turns and pays thirty-five. If it paid thirty-six the game would be exactly even; paying thirty-five leaves 1/37 of every stake behind, which is 2.70 percent.
The same for every cover
Lit pays one to one on eighteen of thirty-seven, a third pays two to one on twelve of thirty-seven. Work either through and you land on 2.70 percent again. There is no cover on this table that is better than another.
Guide
A ring is a lottery you can see
Every pocket is drawn with the same chance, and the whole apparatus is in front of you. Nothing about a ring game is hidden — which makes it the clearest place to see where a house margin actually comes from.
The margin is one pocket
The rewards are priced as if the extra pocket were not there. On a thirty-seven pocket ring that single difference is 2.70 percent; add a second and it becomes 5.26. Nothing else about the game changes at all.
Every cover is the same
A single number, a colour, a column, a dozen — all of them settle to the same margin on the same ring. Spreading across the table changes how often you are paid and by how much, and leaves the expected result untouched.
Patterns in past results
Recording the last twenty outcomes feels like research and is not. Each turn is independent; a run of one colour carries no information about the next. The board that displays past numbers exists because people want it, not because it predicts anything.
