# How a roulette wheel is laid out, and why the order looks random

Published 2026-09-14

Learning the Games

A single-zero wheel head and the layout it feeds. The ring order is not the counting order.

The numbers around a wheel head are not in counting order, and they are not scattered at random either. The ring is arranged so that colours, high numbers and odd numbers are spread as evenly as the geometry allows.

Look down at a single-zero wheel and the first thing that fails to appear is any sequence you would recognise. One is not beside two. Thirty-six is not beside thirty-five. The green zero sits at the top of the ring and the numbers run away from it in an order that seems to have been shaken out of a bag.

It was not shaken out of anything. The ring on a single-zero wheel holds thirty-seven pockets: the numbers one to thirty-six, and a single green zero. The order is fixed, it is the same on every wheel of that type, and it is built to satisfy several constraints at once.

### [Reading a blackjack rule card before you sit down](https://miucasino.com/learning-the-games/reading-a-blackjack-rule-card/)

Four or five printed lines on the felt set the arithmetic of the table before a card is dealt.

Every blackjack table prints its own terms on the felt in a handful of short lines. Those lines, not the dealer and not the shoe, decide what the game is worth.

### [Why baccarat scoring drops the tens digit](https://miucasino.com/learning-the-games/why-baccarat-scoring-drops-the-tens-digit/)

Totals are read modulo ten, so a hand can never be worth more than nine.

A baccarat hand is scored by adding the cards and keeping only the last digit. It is the single rule that makes the rest of the game intelligible.

## Rules Desk

1. Blackjack[The felt states whether the dealer stands or draws on a soft seventeen; the two are different games.](https://miucasino.com/rules-desk/dealer-stands-on-soft-seventeen/)
2. Roulette[A single-zero ring holds thirty-seven pockets and a double-zero ring holds thirty-eight, at the same payout.](https://miucasino.com/rules-desk/house-edge-is-arithmetic-not-luck/)
3. Baccarat[Banker wins carry a stated commission, printed with the rest of the table terms.](https://miucasino.com/learning-the-games/why-baccarat-scoring-drops-the-tens-digit/)
4. Blackjack[Surrender, where a table offers it at all, returns half a wager against the dealer’s up card.](https://miucasino.com/learning-the-games/reading-a-blackjack-rule-card/)
5. Reel games[A paytable states combinations and multipliers; the reel strips that set their frequency are not published.](https://miucasino.com/learning-the-games/what-a-slot-paytable-actually-lists/)
6. Craps[The puck records the round: dark face up for a come-out roll, light face up on an established point.](https://miucasino.com/table-talk/the-sequence-of-play-at-a-craps-table/)

## Around the floor

- Learning the Games[What a reel game paytable actually lists, and what it leaves out](https://miucasino.com/learning-the-games/what-a-slot-paytable-actually-lists/)The paytable behind a reel game is a complete statement of what pays and how much. It is a deliberately incomplete statement of how often.
- Table Talk[Why chip denominations are colour coded, and why the colours vary](https://miucasino.com/table-talk/why-chip-denominations-are-colour-coded/)Chip colour exists so that a stack can be valued from several feet away at speed. The convention is strong, widely shared, and not a standard.
- Table Talk[The sequence of play at a busy craps table](https://miucasino.com/table-talk/the-sequence-of-play-at-a-craps-table/)Craps looks chaotic because several things happen at once and none of them are announced. The order underneath is short and fixed.
- Floor Notes[What independent testing of a number generator actually measures](https://miucasino.com/floor-notes/what-rng-testing-measures/)Testing a random number generator means running its output through a battery of statistical checks. Each check looks for one specific way a sequence can fail to be random.

## Tournament Play

*How a tournament seat differs from a cash seat*

| Feature | Tournament | Cash table |
|---|---|---|
| Chips | Scorekeeping tokens with no cash value | The money itself |
| Leaving | Only by elimination or by the event ending | At any point, taking the stack |
| Forced bets | Rise on a fixed schedule | Fixed for the life of the game |
| Losing a stack | Ends participation | May be replaced by entering again |

- Tournament Play[How a freezeout structure works, and how it differs from a cash table](https://miucasino.com/tournament-play/how-a-freezeout-structure-works/)In a freezeout, everyone pays the same entry once, receives the same chips, and plays until they have none. The chips are not money and cannot become money.
- Tournament Play[What blinds and antes are actually for](https://miucasino.com/tournament-play/what-blinds-and-antes-are-for/)Forced bets exist to make a hand worth contesting. Rising forced bets exist to make a tournament end.

## Letters

- [On playing to a set budget](https://miucasino.com/letters/on-playing-to-a-set-budget/)Almost nothing at a table is decided by the person sitting at it. The rules are printed, the payouts are fixed, the cards fall as they fall. Of the things a player brings into the room, one is entirely their own: the amount they decided on before arriving.That decision has a useful property. It is made away from the table, without a result in front of it, at a moment when the arithmetic is easy to think about clearly. Every decision made afterwards is made under worse conditions.Signed, Miu Casino Weekly
- On learning the rule set before the betting patternThe hours a player spends on staking sequences would be better spent on the printed terms of the table in front of them. One of those two things changes what the game is worth, and it is not the sequence.A rule set can be read in a minute and is the same for everyone at the table. That is exactly why it is worth reading: it is public, it is fixed, and it is the part of the game that is actually knowable in advance.Signed, Miu Casino Weekly
