How Roulette Odds Work?

The odds in roulette are based on the probability of a particular outcome occurring, which depends on the total number of possible results on the wheel. There are two main versions of this game: European roulette (featuring 37 pockets: numbers 1-36 and a single zero) and American roulette (featuring 38 pockets: numbers 1-36, a single zero, and a double zero). The additional double zero in the American version slightly reduces your chances of winning compared to European roulette.

Each type of bet you make, like betting on an individual number, a group of numbers, or a colour, has its odds and payouts. The fewer numbers included in a bet, the lower the chances of winning, but the higher the payout.

Inside Bets

Inside bets are those made on particular numbers or small clusters of numbers located within the main grid of the roulette table layout. These bets provide higher payouts but come with lower chances of winning, making them riskier but potentially more profitable. The inside bets are:

• Split bet;
• Street bet;
• Corner (Square) bet;
• Five Number bet (Basket bet);
• Line (Double Street) bet.

Outside Bets

Outside bets are placed on broader categories, such as colour, groups of numbers, or patterns, rather than on the primary number grid. These types of bets cover a wider range of numbers, offer smaller payouts, but have higher odds of winning, making them more suitable for new players or those employing conservative strategies. The outside bets include:

• Column bet;
• Dozen bet;
• Red or Black bet;
• Odd or Even bet;
• High or Low bet.

Call Bets (Announced Bets)

Call bets, or announced bets, are unique types primarily used in European and French roulette. With these bets, players “announce” their bets to the dealer rather than placing chips on specific numbers. They focus on segments of the wheel rather than the arrangement of the table, and they frequently include complex combinations.

Calculating Roulette Payouts

Roulette payouts are determined by the payout ratio corresponding to the bet type you make. The payout ratio indicates the amount you will earn for each unit staked, excluding your initial bet. Here is a simple step-by-step guide to calculate the payouts:

1. Identify your bet type.
2. Check the payout ratio for that bet type.
3. Multiply your wager by the payout ratio to get your profit.
4. Add your original bet to the profit to get the total return.

Example Calculations

Let’s take a look at some example calculations.

1.Straight-Up bet:

• Bet: $10
• Bet type: straight-up(single number)
• Payout ratio: 35 to 1
• Calculation:
• Winnings: $10 x 35 = $350
• Total return: $350 (winnings) + $10 (original bet) = $360

2.Red/Black bet:

• Bet: $50
• Bet type: red
• Payout ratio: 1 to 1
• Calculation:
• Winnings: $50 x 1 = $50
• Total return: $50 + $50 = $100

3.Split bet:

• Bet: $20
• Bet type: split (covers two adjacent numbers)
• Payout ratio: 17 to 1
• Calculation:
• Winnings: $20 x 17 = $340
• Total return: $340 + $20 = $360

4.Dozen bet:

• Bet: $25
• Bet type: 2nd dozen (13-24)
• Payout ratio: 2 to 1
• Calculation:
• Winnings: $25 x 2 = $50
• Total return: $50 + $25 = $75
