Three roulette wheels are allowed in Chile. Which one is in front of you, and what does the same chip cost on each?

The short answer

A French wheel with one zero, an American wheel with one zero, and an American wheel with two. A single number pays 35 to 1 on all three, and costs 2.70% of the money bet on a wheel with one zero and 5.26% on a wheel with two: almost twice as much for the same payout. Count the zeros on the layout before the first chip goes down.

Leo smiling, explaining with an open hand.

Every roulette table in the country follows the same catalogue, and the catalogue allows three wheels. They look alike from across the room. The difference is one pocket, and that pocket nearly doubles the price of most chips on the layout. Ten seconds at the table tell you which wheel it is.

Three wheels in one catalogue

The national catalogue of games lists the French wheel and the American wheel, and the American wheel in two kinds: with one zero, and with a zero and a double zero. The French wheel has 37 pockets, 1 to 36 and a zero. The American wheel has the same 37 with one zero, and 38 with two. The American game works on the same principles as the French one, and pays the same figures for the same bets.

The French layout carries the even-money boxes on both sides, the American layout on one side. French bets are made with money chips; at an American table each player has a colour of chip, and may choose money chips instead. The five-number bet exists only on the wheel with two zeros.

How to tell them apart at the table

The name does not tell you. Enjoy’s page on its tables heads its roulette RULETA AMERICANA, and Gran Casino de Talca writes Disfruta de los clásicos Black Jack y Ruleta Americana. The catalogue gives that name to the wheel with one zero and to the wheel with two, so a page that says American roulette has not told you how many zeros its wheel has. None of the casino pages we read says it.

  1. Count the zeros

    A 0 and a 00 at the head of the layout: the American wheel with two zeros. A single 0: one of the other two.

  2. One zero? Look at the even-money boxes

    Red, black, odd, even, 1–18 and 19–36 on both sides of the layout: the French wheel. On one side only: the American wheel with one zero.

  3. Ask before the first chip

    If the table is hard to see, ask the croupier how many zeros the wheel has, and what happens to an even-money chip on a zero.

Leo pointing to something to one side.

The zeros sit at the head of the layout, next to the 1, 2 and 3. Look there first. The wheel itself is far from the players and turns fast; the layout is right in front of you and does not move.

Colour chips are a sign of an American table, but not of how many zeros it has, and an American table may also be played with money chips. The limits of each game are posted in the room.

The same chip, three prices

The catalogue prints what each bet pays, not what it costs. The table below is our count: the pockets of each wheel, the numbers each chip covers, and the payout the catalogue gives it.

What each bet costs on each wheelOur count from the pockets of each wheel and the catalogue’s payouts: the share of the money bet the wheel keeps on average, over many spins.

A single number35 to 12.70%2.70%5.26%

The same, with the whole chip lost on a zero, as Enjoy’s page says1 to 1Not on that page2.70%5.26%

One zero against two. On a wheel with one zero every bet that covers numbers comes out at 2.70% of the money bet, the French wheel and the American alike. On the wheel with two zeros the same payouts come out at 5.26%: one more pocket, almost twice the price. The five-number bet, which only that wheel has, costs 7.89%, more than any other bet on any of the three.

The even-money bets. By the catalogue’s rule a zero takes half of an even-money chip, so an even-money bet costs half the price of the bets around it: 1.35% on a wheel with one zero and 2.63% on the wheel with two. On the French wheel the player may instead leave the whole chip in prison for one more spin; by our count over the two spins that costs 1.39%, a shade more than taking half back. These prices are our count from the catalogue’s rule; the catalogue prints no price.

What every spot on the layout pays, chip by chip, is lesson 4.2.

A zero and an even-money chip: two documents

The catalogue says it in one sentence for each American wheel: Si sale el cero (0) y el jugador ha apostado sobre una suerte sencilla pierde la mitad de su apuesta. A chip on red, black, odd, even, 1–18 or 19–36 loses half, and the other half comes back to its owner. Every other chip that does not cover the zero is lost.

One casino page says otherwise. Enjoy’s page on its American roulette writes: En caso que el número ganador sea el cero (o doble cero): … Todas las docenas, columnas y suertes sencillas pierden. That is the dozens, the columns and the even-money bets, all lost on a zero, with no half coming back. The half that comes back is the rule of the Superintendencia’s catalogue; we do not choose between the two for you. At a table that takes the whole chip, an even-money bet costs 2.70% on a wheel with one zero and 5.26% on the wheel with two, the same as the bets around it. Before putting a chip on an even-money bet, ask at the table what happens to it on a zero.

Rules like these differ from casino to casino around the world, and they change what an even-money bet costs.

A cheaper wheel is still a price. Choosing the wheel with one zero halves what most chips cost you; it does not turn the evening around. Decide the money and the time for the evening before the first chip, and stop when either runs out. If the money on the table starts to feel like money you need, read the box below: it names the national self-exclusion, which applies in every casino in the country, and the regulator’s switchboard.

If it stops being fun

If gambling stops being fun, the SCJ self-exclusion applies in every casino in the country. Minimum entry age: 18 (age of majority under Law 19.221; Law 19.995 bars minors from gaming rooms). The casino may ask for an official ID. More on responsible gaming.

Practice: name the wheel, price the chip

Level 1 shows what you can see at a table and asks which wheel it is. Level 2 shows two chips of the same size and asks which costs less. Level 3 stops the ball in a zero and asks what comes back from your chip by the catalogue’s rule. The 10 units on each chip is an example bet, not a suggested bet.

Nothing is bet here, and nothing is random. Each question is a set picture, and the answer is worked out from the same rules and the same count as the rest of the page.

The practice table needs JavaScript. Here is one question from it, with the answer.

Which of the catalogue’s three wheels is this?

  • French, one zero One zero, and the even-money boxes on both sides of the layout: the French wheel.
  • American, one zero Not this one. The American wheel with one zero has its even-money boxes on one side of the layout.
  • American, two zeros Not this one. The American wheel with two zeros has a 0 and a 00 on the layout.
  • Not enough to tell yet Not this one. What you see here is enough to name the wheel.

Count the zeros on the layout first: a 0 and a 00 is the American wheel with two zeros. With one zero, look at the even-money boxes: on both sides of the layout, the French wheel; on one side, the American wheel with one zero. A name on a page and the colour of the chips do not settle it.

Which chip costs less, spin for spin?

  • Chip A A single number, on the American wheel with one zero: 2.70% of the money bet, on average. A single number, on the American wheel with two zeros: 5.26%.
  • Chip B Not this one. A single number, on the American wheel with one zero: 2.70% of the money bet, on average. A single number, on the American wheel with two zeros: 5.26%.
  • They cost the same Not this one. A single number, on the American wheel with one zero: 2.70% of the money bet, on average. A single number, on the American wheel with two zeros: 5.26%.

A price comes from the wheel and the bet together: how many pockets the wheel has, how many numbers the chip covers and what it pays, and, for an even-money chip, what a zero takes.

By the catalogue’s rule, what comes back to you from this chip?

  • Nothing comes back Not this one. By the catalogue a zero takes only half of an even-money chip, not all of it.
  • 5 units come back An even-money chip loses half on a zero: 5 units of your 10 units come back.
  • 10 units come back Not this one. A zero does not leave an even-money chip untouched: half of it is lost.

That is the catalogue’s rule. On a zero, a chip that covers it is paid at its figure and comes back beside the payout; any other chip is lost, except an even-money chip, which loses half. On the French wheel the player may leave the whole even-money chip in prison for one more spin instead. Enjoy’s page on its American roulette says the even-money bets lose on a zero: ask at the table which rule it keeps.

Every question in the practice run is worked out the same way: the wheels are put through the same rules and the same count as the rest of the page, and the answer comes out of that, not out of anybody’s memory.

How the practice run works

Where the questions come from. Every answer is worked out when the page is built, from the catalogue’s rules and our count over the pockets of each wheel. The wrong answers are named mistakes: a name taken for a count of zeros, a payout taken for a price, the chip counted into its own payout, the whole of an even-money chip taken on a zero, a chip out of prison counted as paid.

One strip, and no rounds. Every square on the strip is one question of this lesson, and all of the squares are there from the start. Your first answer fills the square it belongs to; when the squares of one level are full, the next level begins by itself. Practising a question you got wrong turns its cross into “fixed in practice” and does not change the count, because only first answers count.

A question marked “New situation” asks you to use the lesson on a case it did not show.

1A casino page says its tables play Ruleta Americana. How many zeros does the wheel have?

Show the answer

Answer: The name does not say: count the zeros on the layout. The catalogue’s American roulette comes with one zero or with two.

  • The name does not say: count the zeros on the layout The catalogue gives the name American roulette to both kinds, so the zeros on the layout are what tells them apart.
  • Two: “American” means a double zero The catalogue’s American roulette comes in two kinds, one with a single zero and one with a zero and a double zero.
  • One: the American wheel has a single zero One of the two American kinds has a single zero; the other has two.
2The same chip of 10 units goes on a single number, once on a wheel with one zero and once on a wheel with two. What changes?

Show the answer

Answer: The price: 2.70% of the money bet with one zero, 5.26% with two. The payout is the same; the wheel is not.

  • The price: 2.70% of the money bet with one zero, 5.26% with two Same payout, one more pocket: almost twice the price.
  • The payout: the wheel with two zeros pays more Both pay 35 to 1; the catalogue gives the single number one figure on every wheel.
  • Nothing: the same bet costs the same everywhere The extra pocket is not covered by the chip and is not paid: 5.26% against 2.70%.
3On the American wheel with two zeros, which bet costs the most?

Show the answer

Answer: The five-number bet on 0, 00, 1, 2 and 3: 7.89%. The five-number bet belongs to the wheel with two zeros, and it is the dearest bet there.

  • An even-money bet, because a zero can take it A zero takes only half of it by the catalogue’s rule, so it costs 2.63%, the least on this wheel.
  • The five-number bet on 0, 00, 1, 2 and 3: 7.89% It covers five pockets and is paid 6 to 1, a shade short of the figure every other bet follows.
  • A single number, because it pays the most A single number costs 5.26%, the same as every other bet that covers numbers on this wheel.
4A zero comes in at an American table with two zeros. Your chip of 10 units is on red. What do the two documents say?

Show the answer

Answer: The catalogue: half is lost and 5 units come back. Enjoy’s page: the even-money bets lose. This page does not choose between them; the table does.

  • Both say the whole chip is lost The catalogue takes only half of an even-money chip on a zero.
  • The catalogue: half is lost and 5 units come back. Enjoy’s page: the even-money bets lose Two documents, two rules. Ask at the table which one it keeps.
  • Both say half the chip comes back The catalogue says half; Enjoy’s page says the even-money bets lose.
5On the French wheel a zero comes in, and your chip is on black. You may take half back, or leave the chip in prison. What does each cost, on average? new situation

Show the answer

Answer: Almost the same: half back loses half the chip; prison loses 51.35% of it on average. The choice is yours; the catalogue sets what each one does, and the averages are our count.

  • Almost the same: half back loses half the chip; prison loses 51.35% of it on average Prison keeps the whole chip on the layout for one spin it can still lose, so on average it costs a shade more than taking half.
  • Taking half always costs more than prison Half back loses exactly half. Prison loses 51.35% on average: a shade more.
  • Prison costs nothing: the chip comes back whole if black comes next It comes back only if the next spin falls on black; otherwise it is lost. On average prison loses 51.35% of the chip.

Back to the question we opened with. Three wheels, one set of payouts, and three prices: 2.70% for a single number with one zero, 5.26% with two. The zeros on the layout tell you which price you are paying.

How it’s worked out

Rules, numbers, sources and hosts

Where the rules come from. The three wheels, their pockets, their layouts, their payouts and what a zero does are sections II.1 and II.2 of the national catalogue of games, one set of rules for every casino in Chile. Which casino runs which wheel is not on any casino page we read: the pages name the game, not its zeros, so this page names no casino’s wheel.

Numbers. The price of every bet that covers numbers comes from the one table of bets this site computes with, the same table the house edge tool uses: the pockets of the wheel, the numbers the chip covers and the figure it is paid. The price of an even-money bet counts what a zero does to it: half the chip lost, by the catalogue’s rule; on the French wheel, the whole chip kept for one more spin, freed if that spin falls on its side and lost otherwise, which we count over the two spins; and the whole chip lost, as Enjoy’s page says. Each of these is checked against a count of every pocket when the page is built. Nothing is typed in by hand.

What is deliberately absent. The French layout also has bets on two dozens or two columns at once, and bets called aloud by name; this page does not price them. No document we read prints how many spins a wheel makes in an hour, so there is no price of an hour, and the order of the numbers around the wheel is not drawn.

Sources. Every rule on this page carries a button with the sentence it rests on, in the catalogue’s own Spanish or the casino page’s, the publisher who wrote that sentence and the date we read it.

Hosts. Leo and Maya are illustrated characters. Their backstories, a former dealer and a former floor supervisor, are written for the course: neither is a real person, and neither speaks for any casino. The rules and numbers on this page come from the sources it cites, not from their experience.

No promise. Every chip on every wheel has a price. Knowing which wheel you are at lets you choose what you pay; nothing on this page changes where the ball stops, and nothing here says how an evening at the wheel would end.
