History of Roulette

There are many stories surrounding the history of roulette. Different origins from across the world are often told. Stories of games from Ancient Greece, Ancient Rome, China, and France are the most popular.

The most commonly accepted story about its making is the French version. It’s essential to know the others, though, to understand different cultural backgrounds of the game.

Ancient Greece

To pass the time during the war, it’s said that Greek soldiers would gamble with each other. They would do this by drawing symbols on a shield. They would then place that shield on the ground next to an arrow they had also drawn.

The soldiers would then take bets on which symbol the arrow would land on. This early game is similar to modern roulette.

Ancient Rome

The Roman soldiers would also gamble during wartime. This would distract them from the loss and pain they were experiencing. Most of the Roman games used a shield or chariot wheel and followed similar rules to the Greek game.

China

In Ancient China, it’s said there was a board game using 37 animal figurines. The figurines were moved into a “magic square.” This square had numbers that added up to 666.

Dominican monks are said to have adopted this game after Europeans brought them Chinese influences. The game was modified, though. The monks turned the square into a circle and added a zero.

Disclaimer

There’s no direct evidence that any of these stories are true. Still, they are passed along in the gambling world. The most current version of the story is the French one.

Roulette Invented in France

Roulette Invented in France

In 17th century France, a French physicist, inventor, and mathematician invented the roulette wheel by accident. Blaise Pascal was trying to develop a perpetual motion machine. A perpetual motion machine is one that operates without energy from an external source.

The game he invented was similar to two others at the time, Roly Poly and Even-Odd. Both of these games had a spinning wheel and bets on the result of the spin.

Initially, the zero was not on the roulette wheel. It was added in 1842 by Francois and Louis Blanc. This changed the odds for the roulette table. The zero gave the house a more significant edge.

Their wheel was made especially for King Charles III of Monaco. When his kingdom fell into an economic depression, the king introduced the game to his people. The roulette wheel eventually became a symbol of Monte Carlo’s gambling culture.

Roulette became a big part of the economy. At the time, France had outlawed gambling, making the game that much more attractive. Aristocrats and royals played the game continually ever since at the newly built Monte Carlo Casino Resort.

Roulette in the United States

In the early 1800s, roulette was introduced to the United States. This occurred in Louisiana by European settlers.

The wheel differed slightly, adding a 00 to give the house a more significant edge. This changed the odds in the roulette table as it was known. The American wheel has 38 numbers (1 to 36, 0, and 00), and the European wheel has 37 numbers.

Roulette Today

No matter which origin story you believe, there’s no doubt that roulette is still popular today. Available in land-based and in roulette online casinos, millions of people around the world enjoy the game. Understanding the mechanics and odds on a roulette table can help players.

Roulette Bet Types

There are many different types of bets that can affect your odds of winning in roulette. Inside bets are placed on one or more numbers directly. Outside bets are placed on general categories outside of the board. There are different kinds of each bet that determine the odds of the roulette table.

Inside Bets

Straight up Bet

With this bet, you bet on one or more numbers on the layout. If the ball lands on your number(s), you win 35 to 1 on that number. The house edges are different for American and European wheels. The American house edge is 5.26%, and the European house edge is 2.7%.

Split Bet

You can bet on multiple numbers here. Place your chips on the line between two numbers. If the ball lands on either number, you win 17 to 1. The house edges are 5.26% for the American wheel and 2.7% for the European Wheel.

The Street Bet, the Three Number Bet, the Side Bet, the Trio

Although with many names, you only bet on three numbers with this one. Place your chips on the outside border of the numbers. If you win, the payout is 11 to 1. The house edges are 5.26% for American roulette and 2.7% for European roulette.

The Corner, the Square, the Four Number Bet

As you can guess, this bet has you betting on four numbers to form a square. Place your chips on the point where all four numbers meet on the layout. If you win, your payout is 8 to 1. The house edge is 5.26% for American versions and 2.7% for European versions.

The Five Number Bet, the Monster, the Beast

This bet is only found in American roulette. It includes the numbers 0, 00, 1, 2, and 3. The winning payout is 6 to 1. The house edge is 7.89% for this one.

Outside Proposition Bets

The Column Bet

You’ll bet that the winning number will be in a particular column. Place your chips at the bottom of the column you are betting on. The payoff is 2 to 1. If the ball lands on 0 or 00, you lose, as they are not included. The American house edge is 5.26%, and the European house edge is 2.7%.

The Dozens Bet

Here, you bet on a dozen numbers you think the ball will hit. You can only choose layout numbers, not consecutive ones. You bet on P12 (the first twelve numbers), M12 (the middle twelve numbers), or D12 (the last twelve numbers). 0 and 00 count as losses, but the payout is 2 to 1. The house edges are the same as the column bet.

The Odd or Even Bet

There are different odds on roulette numbers. 18 odd numbers and 18 even numbers are on the board. You can place a bet on either side. 0 and 00 count as losses, but the winning bet is even money (1 to 1). The house edges are the same as the column bet.

The High or Low Bet

You can place bets on numbers 1 to 18 or 19 to 36. If you win, the payoff is even money (1 to 1). The house edges are the same as the column bet.

The Red or Black Bet

The roulette odds on red or black is another even bet. You simply pick the color you think will win and earn your winnings. The house edges are the same as the column bet. The roulette odds on green are different because this only applies to 0 (or 00 if you are playing the American version). Roulette color odds won’t differ between red and black.

How to Play Roulette

Playing roulette can be intimidating even for experienced gamblers. It’s essential to understand the mechanics of the game alongside the bets for you to make educated decisions.

Before you play the game either online or live, you can use a roulette calculator online. This will help you determine possible results before you play.

Firstly, you receive your chips from the dealer or croupier in your preferred monetary denomination. Roulette uses a separate set of chips from the rest of the casino. Roulette chips are colorful to keep track of different bets throughout the game.

Next, everyone will begin placing their bets. Place your chips where you think the ball will land. The ball will then be thrown on the wheel by the dealer/croupier. There are a couple of things to remember when placing bets:

  • The first six bets are put on numbers 0 to 36.
  • If you are betting on a column, place your chips on the empty pocket under the three columns.
  • If you’re betting on a dozen, choose the pocket corresponding with the dozen you have chosen (P12 for the first dozen, M12 for the middle dozen, or D12 for the last dozen).
  • If you want to place an outside bet, remember to use red or black, high or low, or even or odd pockets.

Once the ball stops, the dealer will mark the winning bets. Losers will be removed from the board. Winners will then be paid their winnings. All chips are then removed, and the game starts again.

There are many different strategies when it comes to playing roulette. Some players rely on luck while others on skill. Statistical probabilities can be calculated depending on the bet and type of roulette wheel, American or European.

American Roulette Vs. European Roulette

American roulette odds and European roulette odds are different because they use two separate wheels. The European roulette wheel has 37 numbers, while the American roulette wheel has 38. This is because the American wheel has 00, giving the house a more significant edge in the United States.

The odds of winning on the two wheels are different. The odds of winning on the European roulette wheel are 1 in 37. This means your payout will be 35 to 1 (you get paid 35 plus the amount of your original bet). The European wheel has a higher rate of players winning.

The American roulette wheel has the added 00, making the odds of winning lower. The odds of winning are 1 in 38. The difference is not much, but it’s still lower than the European roulette wheel. The payout on the American wheel is 35 to 1, meaning 35 dollars plus your original bet.

The Odds Of Winning in Roulette

Roulette Odds Calculator

Many websites offer roulette odds calculators online for giving players an estimate of what the results of their bet will be. Roulette is a game of chance, but the odds of a roulette table can be calculated with statistics.

The calculators work assuming a player uses the same betting number throughout the game. If you use the same number, you’re more likely to win.

The calculator takes the amount you’re willing to wager for a single betting session. The tool will then calculate three different betting units, a safe unit, a high-risk unit, and a recommended unit. You can then choose one of those units for gameplay, depending on your preference.

Safe Betting Units

Safe betting units allow players to stay at the table longer. Players that are more stingy with money are recommended to use these units. The units also work better online, where low-stakes variables are available.

High-risk Betting Units

High-risk betting units are more suited for high rollers. The calculator generates this unit as the highest, safest bet in the game.

Players that are on a losing streak, get angry, or are anxious about the game should not use high-risk betting units. This is because they are more likely to lose more money than they would prefer while using this unit. Reducing the bet size can save these players a lot of trouble in the long run.

Odds On A Roulette Table

Recommended Betting Units

The recommended unit calculated by the calculator is 2% of the overall bet amount used. The unit given is the one recommended that players use. Players can spend longer at the roulette table and know they have a good chance of winning every round.

If players do use this recommended unit, they are more likely to have fewer losses. Losing streaks will not affect players as much. New players should remember to be happy with the smaller wins with this unit.

Which Unit Should I Use?

No matter the results of a roulette wheel calculator, players should only spend money they are comfortable playing with and occasionally losing. Creating limits for yourself and sticking to them can help in the long run. This means your time at the table will be maximized, and you won’t risk most of your money.

Players should also remember that online calculators are not to be followed 100%. The results provided by these tools are just suggestions. To make the most of the calculator’s results, play around with them and see which works best for you and your budget.

Once you determine the unit that is right for you, stick with it at the roulette table. The probability is a roulette wheel never changes, so sticking with a predetermined amount can keep your winnings and losses somewhat secure.

You can find online calculators, roulette odds charts, and more with a Google search. Make sure to do your research. Always stick with a money amount you feel comfortable with.
