Roulette is one of the casino games in which players can choose from a wide range of bets. Some are riskier than others but, generally, the bets in the game can be divided into two major categories – inside and outside bets. Inside bets are placed in the centre of the table’s layout on individual numbers or on specific combinations of numbers. Inside bets involve a higher risk for players, as their chances of winning with such wagers are smaller. However, they are well worth it, since inside bets have larger payouts when compared with outside bets.

The Straight Up Bet

Straight Up bets are placed on an individual number on the table layout. Players can choose any number they like from 1 to 36, but inside bets can also be placed on zero (or double zero in American roulette).

When players want to make a Straight Up bet, they should place their chips in the middle of the box corresponding to their chosen number. The chips should not touch the outlines of the number box. If several players wish to bet on the same number, their chips are stacked so that they fit in the centre of the box. Players can place as many Straight Up bets as they wish.

Winning Straight Up bets have a payout of 35 to 1. For example, if a player wagers £1 on number 9 and wins, they will collect a total of £36 – their original wager plus a net profit of £35. Please note that the true odds of winning with a Straight Up bet are 37 to 1.

Player wagers £1 on number 9 (red). If the ball lands on 9 they will collect a total of £36.

The Split Bet

The Split is a combination bet that covers two adjacent numbers on the layout. With Split bets, players place their chips on the line between the two adjacent numbers they have chosen. Remember, the two numbers you want to cover are adjacent on the table layout, but they are not necessarily next to each other on the wheel. Winning Split bets pay out 17 to 1.

Player wagers £1 on a split bet that covers 8 (black) and 9 (red). If the ball lands on 8 or 9 they will collect a total of £18.

The Street Bet

The Street bet is also referred to as a Row bet because it covers three consecutive numbers on any given row on the layout – 13, 14 and 15, for instance. Players are expected to place their chips on the line to the right of the three numbers they want to cover with their Street bet. In other words, the chips should be placed on the line next to the first number on the row – in this case, number 13. Street bets have a payout of 11 to 1.

Player wagers £1 on a street bet that covers 13 (black), 14 (red) and 15 (black). If the ball lands on 13, 14 or 15 they will collect a total of £12.

The Square or Corner Bet

The Square or Corner is yet another combination bet that covers a cluster of four numbers on the table layout. To place such a bet, the player must put a chip or a stack of chips in the very centre of the cluster, where the vertical and horizontal lines of the four numbers intersect. Keep in mind that the chip or stack of chips should touch the corners of all four numbers. Winning Square bets pay out 8 to 1.

Aside from being called the Corner or Square bet, this wager type is also known as a four-number wager.

Player wagers £1 on a square bet that covers 8 (black), 9 (red), 11 (black), 12 (red). If the ball lands on one of the chosen numbers they will collect a total of £9.

The Six Line or Quint Bet

As the name suggests, Six Line bets, also known as Quint bets, cover six consecutive numbers on the table layout. This, however, does not mean the numbers are located next to one another on the wheel. The Six Line bet is often referred to as a Double Street because players wager on two consecutive rows. For example, a Six Line bet will cover numbers 25, 26 and 27 on one row and numbers 28, 29 and 30 on the row below. To place this type of inside bet, players need to put their chips to the right, on the line between the rows of numbers they want to cover. A winning Six Line bet has a payout of 5 to 1.

Player wagers £1 on a six line bet that covers 25 (red), 26 (black), 27 (red), 28 (black), 29 (black) and 30 (red). If the ball lands on one of the chosen numbers they will collect a total of £6.

The Five Number Bet

The Five Number bet, also known as a Sucker or Basket bet, can be placed only in American roulette, where there are single-zero and double-zero pockets. As the name itself suggests, players can cover five consecutive numbers with a single chip, namely 0, 00, 1, 2 and 3. The chips for this bet are placed on the line between the zeros and the first row of numbers. Should the ball land on one of these five numbers, the player will be paid at a rate of 6 to 1.

This type of bet should not be confused with the Four Number bet – a wager that can be placed only on a French roulette table where the La Partage rule applies. The Four Number bet is also placed on 0, 1, 2 and 3, but its odds are better.

Five Number bets are considered the worst type of wager to make on a roulette table, so players are advised to steer clear of them. In American roulette, the house edge is 5.26% on all inside and outside bets, the Five Number bet being the only exception – it gives the house a whopping advantage of 7.9%.

Player wagers £1 on a five line bet that covers 0 (green), 00 (green), 1 (red), 2 (black), 3 (red). If the ball lands on one of the chosen numbers they will collect a total of £7.

Snake Bet

The Snake bet is the last of the inside bets that roulette enthusiasts can choose. Winning Snake bets pay the same as winning Dozen bets, more specifically 2 to 1. Interestingly enough, this bet type was named after the zig-zag pattern that is formed once all 12 numbers it covers are linked. The numbers Snake bets cover include 1, 5, 9, 12, 14, 16, 19, 23, 27, 30, 32 and 34. What roulette fans should remember is that placing this bet may not always be possible. If Snake bets are accepted, however, the chips should be placed on the lower corner of the box that corresponds to 34.

Depending on the casino at which players are gambling, they might see that a snake is depicted on the betting layout, its body winding precisely around the numbers mentioned above.
