If you have rudimentary knowledge of roulette, you are probably familiar with most of the inside and outside bets listed on the main table layout. However, this classic casino game offers an additional set of advanced wagers that allow the player to bet on specific groups of numbers as they appear on the wheel.

Known as call or announced bets, these wagers are available on single-zero wheels. They are usually announced by the dealer. Covering a call bet on the layout requires multiple chips.

You are probably wondering what the point is of introducing additional wagers in a game that is already laden with standard betting opportunities. Well, call bets not only make roulette more interesting but also give you better odds of winning by allowing you to cover entire wheel segments with as few chips as possible. In this article, we are going to discuss the different types of call bets, how they work, and how they compare with standard roulette wagers in terms of winning potential.

The Racetrack in Single-Zero Roulette

1The Racetrack

Roulette tables that allow call bets usually feature an additional section on their layouts called a racetrack. Oval in shape, the racetrack lets you place multi-chip wagers that cover entire groups of numbers appearing in adjacent pockets on the wheel.

2Racetrack Layout

Essentially, the racetrack is an exact replica of the single-zero wheel. It contains numbers 0 through 36 in the exact order in which they appear on the roulette wheel. The 37 numbers are listed in numerical order on the layout, whereas the numbers on the wheel are arranged in a seemingly random sequence.

3Placing Call Bets

The random sequencing of numbers on the wheel serves a two-fold purpose: it balances the wheel and makes it impossible for players to predict where the ball will land. Because the order of numbers on the wheel differs from that on the layout, call bets are placed as combinations of straight-up, corner, split, and trio bets.

Common Types of Call Bets

Let’s start off by explaining why call bets are named this way. Players sometimes refer to them as announced bets, using the two terms interchangeably. With that said, there is a difference between the two types of wagers, albeit a subtle one.

Both call and announced bets are posted on the racetrack and require players to verbally announce what wager they want to make. The distinction between the two lies in whether the player must place chips on the table when announcing the bet.

With announced bets, you need to post the required number of chips on the racetrack so that the dealer knows you have enough money to cover the cost of your combination wager. This must happen while the spin is still in progress, before the ball determines the outcome of the round.

Call bets differ in that the player still verbally declares the desired wager but does so without placing any chips on the layout to cover it. This can be problematic if the call bet loses and the player cannot pay the house.

In some countries, such as the United Kingdom, calling your bets without posting chips is considered gambling on credit. As such, it is strictly prohibited by law. Below, we list the main types of call bets. Note that some of them are unavailable at all tables.

Tiers du Cylinder

Tiers du Cylindre means “one-third of the wheel,” an apt name for this call bet. It covers 12 of the 37 numbers – 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, and 33. These numbers occupy the side of the wheel opposite the Voisins du Zero section.

You need 6 chips or multiples of 6 chips to place this bet. The chips are set on the following splits: 5/8, 11/10, 13/16, 23/24, 27/30, and 33/36. If any of the 12 numbers appears on the next spin, the player receives 17 units for the winning split but loses the five units staked on the remaining splits.

The probability of winning with Tiers du Cylindre is a respectable 32.43%. This combination bet is not always referred to by its French name; in South African casinos you may hear it called Series 8/5. At some roulette tables it is also known as the Small Series bet.


Voisins du Zero

The Voisins du Zero (or “Neighbors of Zero” in French) is popular with seasoned roulette players – and for good reason. It covers nearly half of the single-zero wheel, specifically the 17 numbers situated opposite the Tiers numbers: 22, 18, 29, 7, 28, 12, 35, 3, 26, 0, 32, 15, 19, 4, 21, 2, and 25.

A quick glance at the wheel shows why it is named this way: nine numbers lie to the left of zero, seven to its right, plus the zero itself. This is easily the most famous call bet because it offers a solid probability of 45.94%.

The bet requires at least 9 chips – 1 unit on each of the five splits 4/7, 12/15, 18/21, 19/22, and 32/35; 2 units on the corner 25/26/28/29; and 2 units on the trio 0/2/3. The payout depends on which component wins: Voisins pays 17 to 1 for a winning split, 11 to 1 for the trio, and 8 to 1 for the corner.


Orphelins

You have probably noticed that the Voisins and Tiers sections nearly split the wheel in half. The two smaller sections that remain consist of the so-called “orphan” numbers, or Orphelins in French. One section includes numbers 17, 34, and 6, while the other comprises 1, 20, 14, 31, and 9 – eight numbers in total.

There are two variations of this bet. The more common, Orphelins en Cheval, requires 5 chips: 4 units on the splits 6/9, 14/17, 17/20, and 31/34, and 1 unit straight up on number 1. If you are wondering, Cheval is the French term for split bets. Provided that any orphaned number shows, you win at odds of 17 to 1 for the splits and 35 to 1 for the straight-up bet.

The alternative is Orphelins en Plein, where you bet straight up on each orphaned number. You need 8 chips – or multiples of 8 chips – for Orphelins en Plein. Because it covers only eight numbers, the wager is less likely to win than Tiers or Voisins, resulting in a probability of 21.62%.


Jeu Zero or Zero Spiel

For the sake of accuracy, we should note that Jeu Zero is not strictly a French bet. The wager originated in German casinos, where it was called Zero Spiel, meaning “zero game” or “zero play.” As the name suggests, the bet revolves around the zero.

Jeu Zero is a miniature version of Voisins du Zero; it targets pockets close to zero but covers fewer numbers: 15, 32, 0, 26, 3, 12, and 35. The player needs 4 chips to place the bet.

The chips are distributed on the splits 0/3, 12/15, and 32/35, plus 1 chip straight up on number 26. A hit on 26 pays 35 to 1, while any of the splits pays 17 to 1. The probability of Jeu Zero is 18.92%.


The Neighbors

Neighbor bets should not be confused with Neighbors of Zero (Voisins); they form an entirely different category of wagers. The classic Neighbor bet centers on any chosen number plus the two adjacent numbers on each side of it on the wheel.

Essentially, you place a straight-up bet on each of the five numbers, aiming for a payout of 35 to 1. For example, a bet on 13 and its neighbors covers 11, 36, 13, 27, and 6. Some online roulette variants (such as those by NetEnt and Microgaming) let players adjust the number of neighbors, offering a choice of 1 to 8.

Suppose you select number 9 and eight neighbors on either side, covering a large portion of the wheel (5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 3, and 35). In this case, you risk a total of 17 chips for the chance to win 35 chips, with a probability of 45.94% – the same as Voisins.

By default these are 5-chip wagers, so be sure to specify the number of neighbors if you intend to cover more than two adjacent pockets on either side of your chosen number. The probability of winning with the default 5-chip Neighbor bet is lower, at 13.51%.

If you are feeling adventurous, you can combine several Neighbor bets on the same spin. One example is a bet on 8, 11, and 13 plus their neighbors: you risk 15 chips, covering numbers 6, 10, 23, and 27 with 1 chip each; numbers 8, 13, 30, and 36 with 2 chips each; and number 11 with 3 chips.


Final Bets

The name of this call bet is self-explanatory. A Final bet includes every number on the layout that ends with the same digit – for example, 5, 15, 25, and 35. The number of chips you must stake depends on the digit you choose: you need 4 chips for digits 0 through 6 and 3 chips for digits 7, 8, or 9, as the wheel stops at 36.

There are several ways to place this wager, the most common being Finale en Plein. Here you bet straight up on each selected number and collect 35 units for every unit wagered when you win. Finale en Plein 8, for instance, consists of three straight-up bets on 8, 18, and 28, while Finale en Plein 3 requires four chips on 3, 13, 23, and 33.

Finale en Cheval differs in that some numbers are covered with split bets. Again, the exact chip count depends on the final digit. For example, Finales Cheval/Plein on 6 and 9 is a 4-chip wager that places chips on the splits 6/9, 16/19, and 26/29, plus a straight-up bet on 36.

Another example is Finales en Cheval on 7 and 10, which requires one chip on each of these splits: 7/10, 17/20, and 27/30. Finale Cheval/Plein 2 and 1 calls for five chips: splits 2/1, 12/11, and 32/31, plus straight-up bets on 21 and 22 because they are not adjacent on the layout.

The probability of winning with a Final bet depends on its coverage. It is 10.81% and 8.11% when you bet the numbers straight up; 18.92% for Cheval/Plein with 7 numbers; 16.22% for Finale en Cheval with 6 numbers; and 21.62% for Cheval/Plein with 8 numbers.


Full Completes

This wager is favored mostly by high rollers because it calls for a large number of chips. It is also known as a Maximum bet, as players typically stake the table maximum on straight-up, split, corner, street, and double-street bets.

It is a complex wager that can require up to 40 chips. The structure consists of 1 straight-up bet on the base number, 4 split bets, 1 street bet, 4 corner bets, and 2 double-street bets. The example below illustrates a bet on 20 at the maximum, with a $100 ceiling for inside bets. If you are playing online, you can usually make the same wager for less than the maximum.

  • 1 chip on number 20 (to a maximum of $100)
  • 2 chips on the 17/20 split (to a maximum of $200)
  • 2 chips on the 20/21 split ($200 maximum)
  • 2 chips on the 19/20 split ($200 maximum)
  • 2 chips on the 20/23 split ($200 maximum)
  • 3 chips on the 19/20/21 street ($300 maximum)
  • 4 chips on the 17/18/20/21 corner ($400 maximum)
  • 4 chips on the 16/17/19/20 corner ($400 maximum)
  • 4 chips on the 19/22/23/20 corner ($400 maximum)
  • 4 chips on the 21/20/23/24 corner ($400 maximum)
  • 6 chips on the 16/17/18/19/20/21 double street ($600 maximum)
  • 6 chips on the 19/20/21/22/23/24 double street ($600 maximum)

There you have it – 40 chips on the layout and a total of $4,000 in action. If the inside-bet maximum at your table is higher, say $1,000, you would need to risk a staggering sum on a single spin.

The Full Complete bet in this example covers nine numbers, so its chances are lower than those of broader call bets like Voisins. Its probability is 24.32%.

If you do win, the number of chips you collect depends on the base number. In the 40-chip example above, you would receive 392 chips. Certain numbers require fewer chips to complete and therefore return smaller payouts, as shown below:

  • 0 requires 17 chips and pays 235 chips
  • 1 and 3 require 27 chips and return 297 chips
  • 2 costs 36 chips and pays 396 chips
  • Numbers from the first column (4 to 31) and third column (6 to 33) require 30 chips and pay 294 chips
  • Full Completes on 34 and 36 are 18-chip bets and return 198 chips
  • 35 requires 24 chips and pays 264 chips

You may wonder how the payouts are settled when the winning number is adjacent to your base number – for instance, when you wager 40 chips on 20 to the maximum and 23 appears.

Croupiers usually apply the station method, which involves counting the ways the winning number connects to the complete wager. In our example, 23 does so in four ways (or stations): two corners (20/23/21/24 and 19/20/23/22), one double street (19/20/21/22/23/24), and one split (20/23).

The croupier multiplies the number of stations by 30 and then adds the remaining stations – 8 in this case – like so: (4 x 30) + 8 = 128. Thus, the player should be paid 128 chips for a Full Complete on 20 when 23 hits.

We can hardly understand why anyone would attempt this bet unless they are as wealthy as Mike Ashley, the billionaire owner of Newcastle United, who famously won £1.3 million with a bet on 17 to the maximum in 2008 at London’s Mayfair.

Other Advanced Bets to Make at the Roulette Table

The call bets discussed above represent only the most popular options. Roulette offers a whole array of advanced novelty wagers, including the four special bets outlined below. They are ideal for players who enjoy experimenting and wish to diversify their gaming sessions.

Black and Red Splits

We discuss these together because they are virtually identical. As the name implies, they are split bets on same-colored numbers that sit next to each other on the layout. Keep in mind the numbers themselves are randomly positioned on the wheel.

The Red Splits are 9/12, 18/21, 16/19, and 27/30, while the Black Splits are 8/11, 10/13, 17/20, 26/29, and 28/31. You cover only 10 or 8 of the 37 pockets, which gives probabilities of 27.03% and 21.62%, respectively. If any selected number hits, the casino pays the standard split-bet odds of 17 to 1.


The 007 Bet

Anyone who has watched the James Bond films knows that baccarat is the secret agent’s game of choice on screen. In Ian Fleming’s novels, however, 007 is an accomplished roulette player.

It is therefore fitting that one of roulette’s novelty bets bears his code name. The wager is called 007, and it takes its name from the shape the chips create on the layout.

The bet includes numbers from all three dozens and covers nearly the entire wheel, leaving out only a few pockets. In effect, it combines straight-up and corner bets.

You place straight-up bets on 4, 7, 9, 6, 16, 19, 18, 21, 28, 30, 32, 33, and 36, along with the following corner bets – 1/2/4/5, 2/5/3/6, 8/9/11/12, 8/11/10/7, 13/14/16/17, 14/17/15/18, 20/23/24/21, and 20/23/22/19.

The 007 bet pays 11 to 1 on corners and 35 to 1 on straight-up numbers. You need at least 21 chips for this wager. It covers all numbers from the first two dozens plus five from the third, giving it a probability of 78.38%.


The Snake Bet

The Snake bet gets its name from the snaking pattern the chips form on the layout. It is unavailable in most online versions, although you can place it manually. The wager appeals to players who like dozen bets, as it also involves 12 numbers, but they are scattered across the layout rather than grouped sequentially.

You bet straight up on 1, 5, 9, 12, 14, 16, 19, 23, 27, 30, 32, and 34. If any of these 12 numbers hits, the casino pays the standard straight-up odds of 35 to 1. The probability of winning is the same as a dozen or column bet, 32.43%.


The Random 7 Bet

This wager is particularly interesting because it combines split, corner, street, and straight-up bets. It is called the Random 7 because you place seven chips randomly on the layout. Thanks to the mixed bet types, you end up covering more than seven numbers.

Why seven chips? The number 7 is regarded as lucky in many cultures and is often linked to perfection, prosperity, and renewal. Here is one example of a Random 7 bet – you post 1 chip straight up on numbers 11 and 14, 1 chip on the corner of 1/2/4/5, 1 chip on the 16/17/18 street, 1 chip on the trio of 0/2/3, and 1 chip on each of the 21/20 and 28/29 splits.

Naturally, you can distribute your seven chips in any pattern you like. The payout depends on which component of the bet wins: 35 to 1 for a straight-up, 17 to 1 for a split, 11 to 1 for a street, and 8 to 1 for a corner. The probability varies with your coverage and is 40.54% in the example above, which covers 15 numbers.

How Call Bets Measure against Standard Roulette Bets

The probability of winning

Call and Advanced Bets Chart

Before we proceed further, we would like to point out that all call bets discussed in this article carry the same house edge (2.70%) as the other wagers available in single-zero roulette. That said, call bets still merit consideration because they offer players fairly decent odds.

The probability of winning with some of these standard announced wagers is quite high, ranging from 8.11% to a remarkable 45.94%. This is almost as favorable as the 48.65% odds for even-money bets.

The key difference lies in the payout you receive when you win. Some call bets, such as Voisins du Zero, provide nearly the same table coverage yet deliver considerably larger payouts compared with even-money propositions that pay at odds of 1 to 1.
