Mastering Roulette: Strategies for Betting on Colors

Although the colors red, black, and green are separate characteristics, they are similarly familiar to any gaming gimmick associated with casinos. The colors provide the basis of the game's rules and give the game a red, black, and green dress code. The game is structured to generate a profit for the game's operator.

Therefore, the rewards are less than the odds of winning. The paytable of the game cuts down on the odds a bit and gives the game such a strong edge to the house that you will ultimately lose money from playing roulette against a casino.

What color wins more frequently than others in roulette and how you can use that knowledge to develop a strategy for placing bets in roulette? I'll start answering these questions by explaining how frequently each of the game's three colors win.

Red wins

On an American roulette wheel, there are 18 red numbers: 1, 3, 5, 7, 9, 12, 14, 16, 18, 21, 23, 25, 27, 30, 32, 34, and 36. These represent 47.4 percent of the wheel's numbered locations. Therefore, assuming you always place a bet on red for every spin you will win approximately 47.4 percent of the time. Each winning red bet returns at 1 to 1 odds. You receive your original amount of money placed on the bet back plus One dollar for each dollar you placed. For example, if you had wagered $10 on red and won, you would be paid $20 ($10 + $10). If you place a bet on red every time at 50 opportunities per hour; then based upon averages you should win 23.7 of the next 50 spins (for approximately $237) and lose on the remaining 26.3 spins for a total of approximately $263. Ultimately, you should anticipate losing approximately $27 per hour.

European roulette layouts

Since European roulette layouts have the same number of red spaces as American roulette layouts but One fewer space overall, the probability of even money red bets differ slightly. Since red spaces constitute 48.6% of the board, you should win on approximately 24.3 of the next fifty spins and lose on approximately 25.7 of the next fifty spins. With each bet costing you $10, this equates to earning $243 in profits per hour versus losing $257 per hour. While there is only a very minor advantage to the casino with regards to expectations, it is still an advantage to the casino. Players who choose to bet red could reasonably expect to lose somewhere in the neighborhood of $14 per hour on European roulette layouts.

Black wins

As previously stated, bets made on black or red are essentially equivalent bets with alternative names. Therefore, if you make a bet on black you have the same probability of winning as if you made a bet on red. All of the information contained within this article is predicated upon faith -- not logic. There are eighteen black spots located on an American roulette wheel: 2, 4, 6, 8, 10, 11, 13, 15, 17, 19, 20, 22, 24, 26, 28, 29, 31, 33, and 35. As such, there are forty-seven and four-tenths percent of the places on the wheel that are black (just like red). Assuming you continue to bet on black every spin you should win forty-seven and four-tenths percent of the time. Successful black bets pay out at 1 to 1 odds just as successful red bets pay out at 1 to 1 odds. Similarly, if you bet on black for every spin at fifty opportunities per hour; then based upon averages you should win twenty-three point seven of the next fifty spins for approximately $237 and lose on the remainder of the spins (approximately twenty-six and three tenths) for approximately $263. Ultimately, you should expect to lose approximately $27 every hour.

Green wins

Two green spaces are present on an American roulette wheel One marked zero (0) and the other marked double zero (00). This totals thirty-eight spaces on the American wheel; therefore thirty-six spaces are divided among the numbers zero to thirty-six and colored black or red; thus, two spaces remain colored green (zero and double zero). Therefore, there are two point six percent of the wheel's spaces filled with green (two spaces/ seventy-eight spaces = .026). Therefore, if you chose to bet on one of those green spaces, you would win approximately two point six percent of the time. The payoff on successful bets made on the single- or double-zero green space is thirty-five to One.

Therefore, if you wagered $10 and won, you would receive $360. However, since there is a sixty-five percent chance of losing (or at least breaking even); after fifty hours of betting at $10 per hour, you can expect to have wagered $490 and seen only approximately $68 worth of those $360 payments ($360 * .135). That equates to an approximate $418 loss for every fifty hours spent betting on the single- or double-zero green space. On European roulette wheels, there exists a slight difference in terms of the likelihood of green space occurrences compared to American roulette wheels. There exists only One green space on European roulette wheels; therefore there exist thirty-seven total spaces. Therefore green occurs roughly two point seven percent of the time; therefore you can expect to see about One point five of those $360 payments every fifty hours. The stats are essentially identical to American roulette games in terms of paying out large amounts for rare events.

Mostly preferred color

Green occurrences are far less common than black or red occurrences. For instance, there exist thirty-six black or red occurrences for every two green occurrences; therefore, black or red occurrences are eighteen times more probable than green occurrences. Conversely, green occurrences are thirty-six times more probable than black or red occurrences in European roulette games. Before I discuss whether black or red roulette is more popular; I wanted to talk briefly about those annoying green roulette slots. Regardless of whether you're playing an American or European layout, according to the game's algorithmic design; you can expect to see a green space occur once every fifty spins. To test this hypothesis, I visited an American-fac ing casino website that offered free-play money betting options. I was provided with $5,000 in free play dollars and allowed to play either an American or European roulette layout.

First, I tested the American layout. I made a $10 bet on the single green space zero (0) and spun for fifty times. It took me thirty-four spins before I saw a green space; however it wasn't a zero (0), it was a double zero (00). I didn't win; however, I got some evidence that helped illustrate how roulette works in the short-run. The subsequent sixteen spins were uneventful; illustrating how much variability exists in roulette within a relatively short period of time. Unfortunately; despite seeing a green space in my initial fifty spins on American roulette, I didn't win; however maybe my luck would be better with the European version. It worked; unexpectedly so. It took me forty-six spins; however eventually I hit the green zero (0) space for a $360 payment. Unfortunately; it cost me $460 to achieve this victory; showing that there is an inherent flaw in creating a "bet on green every time" strategy regardless of occasional victories.

Favorite color

Many people gamble on their favorite game  including roulette players  however, many base their decision solely on personal Preference rather than any logical reasoning. Can there be any kind of mathematical way to determine which color is favored over others? Are there ways to find a roulette wheel that has some type of bias available in modern day? In the short term it appears as though certain wheels may favor one color over another; however short-term results may be misleading when dealing with games intended to be played hundreds of thousands or millions of times throughout their lifespan. Trends are easier to recognize after several hundred results rather than tens of thousands. Time generally tends to cancel out variations in games like roulette. Nonetheless, I conducted another simulation by simulating an American and European roulette wheel through One-hundred results each to demonstrate what a player might experience in terms of black vs. Red outcomes.

Simulation results: American roulette wheel

I decided to make a $10 bet on black for One-hundred results. It seemed obvious based on the First ten results that betting on black was some sort of secret no-loss strategy. I was up $60 after eight of my First ten results were black. Of course things evens-out with time; and after One-hundred spins we achieved forty-nine black, forty-eight red and three green results. After one hundred $10 bets made on black, I earned $490 and lost $510.

Simulation results: European roulette wheel

It was apparent after ten spins that a trend existed on the European wheel. I experienced two green results, which was more than I anticipated; but eight remained evenly split between black and red. Therefore after ninety additional spins, I completed with forty-seven black results and forty-nine red results along with four green results. My black bets produced earnings totaling $470 and losses totaling $530.

Conclusion

You cannot beat the house in roulette by betting on any of the three colors available in roulette. However if you simply wish to simplify your betting and enjoy yourself playing roulette all night at its typical pace; then there is no problem with betting on black or red and enjoying yourself playing roulette all night long at its typically slow pace. Roulette is cheaper for an hour than attending a movie or racing go-karts based upon estimated hourly loses for even-money bets -- which is indicative of how cheaply you can afford to spend an hour playing roulette at home during off-hours or locally at your local casino for leisure purposes only. Therefore if betting on black or red makes the evening exciting; then go ahead and bet on either color.

FAQs: Understanding roulette outcome frequencies & Color Betting

How often does red win in roulette?

Red occupies forty-seven point four percent of all slots on an American roulette wheel; therefore there are eighteen red numbers located at positions #1 thru #36. If you continually place bets on red, then you will win approximately forty-seven point four percent of all spins; therefore your expected hourly loss is slightly greater than your expected hourly win. While placing bets on red is clearly unfavorable due to the house-edge, however, your expected loss is slightly less than placing bets on red in European roulette.

How frequently do blacks win?

Black wagers have the same chance of winning as do red wagers; therefore there are eighteen black numbers located at positions #2 thru #36; therefore your chance of winning at least forty-seven point four percent of all spins -- and your expected hourly loss is equal to your expected hourly win while placing bets on blacks; therefore your expected loss is similar to placing bets on red due to the balanced nature of color wagers in roulette.

How frequently does green win & what are payouts?

Green occurs far less frequently than either black or red; therefore there are only two green numbers (#0 & #00) located on an American roulette wheel; therefore green accounts for two point six percent of all slots; therefore your chance of winning at least two point six percent of all spins; successful wagers made on either single-or-double-green-space have a payout ratio of thirty-five to One; therefore if you make a successful wager for $10 you will receive an additional $360; however your expected hourly loss is greater than your expected hourly profit due to the low frequency of wins and large payout ratio.

Which color has more player Preference?

Player preferences between black and red are largely arbitrary and not based upon scientific evidence; therefore, neither color has an advantage over the other; however green is far less preferable than either black or red due to its infrequency; however due to its relatively large payout ratio green is also attractive to some players despite its low frequency.

Are there differences between bets made on American vs European roulette boards?

The greatest differences between American & European roulette boards lie primarily in their respective sizes; therefore American roulette boards consist of seventy-eight spaces while European roulette boards consist of thirty-seven spaces; however aside from size the primary difference lies in their respective numbers of green spaces -- therefore American boards have two green spaces (#0 & #00) while European boards have only One green space (#0); therefore due to these differences American boards offer a slightly larger house edge than do European boards; therefore regardless of where you play your expected loss is ultimately unchanged due to at least One green space existing somewhere on all wheels.
