AI Summary

This video tests the classic column and dozen betting strategy in roulette, where the player covers two dozens or two columns plus the zero. The host demonstrates the strategy in real-time, explaining the betting mechanics, profit calculations, and the need to triple bets after a loss to remain profitable. The test yields a profit of R$175 in a short session, but the host acknowledges the strategy's high risk due to the necessity of tripling bets after losses.

[00:03]
Popularity of Column/Dozen Strategies

Column and dozen strategies became popular in Brazil about 5 years ago, with many selling courses solely on this method. Over time, the market evolved and these strategies fell out of favor.

[00:47]
Motivation to Re-test

The host was motivated to re-test the strategy after a WhatsApp community discussion where many claimed they still use column/dozen strategies successfully.

[01:30]
Strategy Overview

The strategy involves covering two dozens or two columns (24 numbers) and also betting on zero to protect against it. The goal is to cover most numbers while leaving only 12 numbers uncovered.

[02:11]
Explanation of Dozens and Columns

A dozen is a set of 12 numbers: first dozen (1-12), second (13-24), third (25-36). Columns are vertical: first column starts with 1, second with 2, third with 3.

[03:37]
Betting Example

The host bets R$50 on each of two dozens (total R$100) and R$10 on zero (total R$110). When a dozen hits, it pays 3x the bet, resulting in R$150 return, net profit R$40 after subtracting the losing dozen and zero bet.

[05:16]
Doubling vs Tripling

If the bet loses, doubling the bet still results in a loss (R$15 loss). To make a profit, the bet must be tripled. Example: tripling to R$150 per dozen yields R$450 return, net profit after accounting for previous losses.

[06:51]
Session Result

In a short session, the host made R$175 profit. The strategy has a high success rate but high risk due to the need to triple bets after losses.

The column/dozen strategy can yield quick profits in roulette, but it carries significant risk because losses require tripling bets to recover, which can escalate quickly. The host advises testing strategies thoroughly before committing real money.

[00:03] to make a profit? When roulette became popular here in Brazil about 5 years ago, when it became a craze, when it arrived, people used these column and dozen strategies a lot. These were strategies that everyone used. So much so that

[00:16] many people came who did live streams, selling a course solely on that, column by column. But over time, like any market, everything becomes more modern. So, something longer worked. People who believed that before, don't believe it anymore. After a

[00:31] long time, it's been years since I last played this style, I'm going to make a video for Why would I do that? I was community on WhatsApp, which includes bettors who understand the game and

[00:47] were exchanging ideas about this and a lot of people said they still play Colonid and that they manage to get results. That kind of stuck in my head. I don't like to play a strategy before testing it. So if someone says, "Dude, I

[01:02] I'm never going to say, 'That's a horrible strategy.'" No, you first need to test it, understand how it works. There are people who, well, it seems like they think they're the king of the world; only their strategy works, only they make money. Maybe they don't

[01:16] deposit. So don't believe everyone. When you hear something, look for more information about it, test it, filter it, analyze it, catalog it, precisely because of that—I'm not going to bet on

[01:30] making this video for you, okay? I 'm going to do it exactly like it used to be, okay? I'm going to do the following: in these strategies I'm going to go into, we're going to cover two dozen or two columns. For those of you who don't

[01:42] know, for those who are more familiar with roulette, roulette has 37 numbers, 36 normal numbers and zero. Zero is also a normal number, but why is there a zero? To have this number... To win at roulette, right?

[01:56] black and it lands on zero, we you bet on red and it lands on zero, you lose everything, okay? Unlike it's a tie, you get a return. No, not here. You have to cover the zero as well. That's

[02:11] the zero, covering the zero to cover it. So, what am I going to do? I'm going to analyze the patterns here. I'm always going to try to cover two dozens and two dozen and a column are, let's go. What is a dozen? As the name itself says,

[02:27] it's a set of 12 numbers. So, the first dozen is from 1 to 12. Look, everything, everything that's blank is the first dozen. Everything that's here, look, is the second dozen. So, those are the numbers from 13 to 24, right? 12 numbers. And the third

[02:40] dozen is the same thing, it's The numbers are from 25 to 36, okay? Each dozen has 12 numbers. And that's how it works, okay? And what is a column? A column is this here, look. There are two, right, which are horizontal, and the columns are vertical. So here,

[02:56] look, is the first column, here is the second column, and here is the third column. Wow, but how am I going to memorize this? It's easy. The first column will start with one, look, one is the first column. Two is the entire second column,

[03:08] three is the entire third column, understand? So, basically, that's how it is, okay? How do you bet on them? By clicking here, look. Here you will bet on the first dozen, column, second column, third column.

[03:20] or two columns. We will leave only one out, right? Whether it's a column or a dozen. Since the roulette wheel has 36 numbers, excluding the zero, 36 numbers. If we are covering two numbers, we want So, what am I saying? We're going to cover 24 numbers and leave 12

[03:37] out, taking out the zero, because we're also protecting the zero. Okay? So, look, here I'm analyzing that since the number five, go. The first dozen is absent, so the five makes some turns that don't

[03:50] so the five makes some turns that don't come up. Then came 1, 2, three numbers from the third dozen and three numbers from the second dozen. It came up on number 26. Now, what am I going to do? I'm going to take a small bet here now. Notice that it's alternating

[04:04] between the numbers from the second and third dozen that I'm going to take. I'm going to take here, dozen that I'm going to take. I'm going to take here, with R$ 50, the numbers from the first with R$ 50, the numbers from the first dozen and the numbers from the second dozen, right?

[04:16] going to protect here, look. If I'm entering with R$ 100, I'm going to protect here, look, with only R$ 10 on the zero, okay? That is, 110 in this play. I'm betting R$ 110 in this play. I'm betting R$ Okay, so I bet R$100 in total

[04:31] on the two dozens, 50 on each, and R$10 on the zero. Let's see what happens. Look, it came up Let's see what happens. Look, it came up on the number 15, paid the 15, so out of 110 it will give me back 150. That is, I had a profit of R$40 . Why? I'll explain

[04:48] So, what am I going to do? I'm going to repeat the play. But instead of I'm going to bet five. Instead of betting on the second dozen, I'm going to bet on the first and third dozen now. Got it? So, totaling 105

[05:01] in this play, okay? I bet R$100 on the dozens, 50 on each, and R$5 on the zero, which is 5% of the total value. That is, 5% of R$100 is... How much? It's CCO. So, it covered the zero. Okay? There's a detail in this strategy. If it doesn't hit, if

[05:16] I'm wrong, I have to double, no, I have to triple to make a profit. Okay? Look, it came on 26, exactly what I said happened, they are alternating. So here I already had R$ 45 in profit, totaling, I have R$ 85

[05:30] 12,000. What am I going to do? I'm going to repeat it again and I'm going to take my chip from the third pair and put it on the second. That is, I'm entering the will come soon, and I'm entering the second one because it's

[05:43] entering the second one because it's alternating, right? I could enter the two that are coming more often, the second one, the third one, I could, but as I said, I think the first one will come soon. I don't know any

[05:55] send them in the comments so I can test them another alright? If you know, very assertive strategies. I'm testing here what I think will work. Look, it came up on 21. See? It happened again,

[06:08] guys. It's almost over, man. I've already got three correct numbers. What am I going to do? I'm going to repeat it again and put 50 here on the third one, because, look, put 50 here on the third one, because, look, since number 15, it's been the second

[06:21] dozen, third, second dozen, third, second dozen, third, second dozen, the tendency is to come back on the third. Once again I'm putting R$ 100 on the dozens, 50 each, and protecting the zero with 5% of the bet, that is, R$5.

[06:36] 's frantic, but if I get this one right , I think I'll pause and we're wrong we have to triple. Okay? It's coming up on number one, see? This one appeared. I was already missing a

[06:51] lot of numbers in the first dozen, like the five, right? So, just here, in a few minutes, I made R$175. I'll do a calculation with you. If I'm a calculation with you. If I'm betting R$50 on each dozen, 50 +

[07:04] 50, 100 plus the R$5 from the zero, R$105, right? Okay. G, how much does it pay when you get a dozen or a column right? Guys, it will always pay three times the amount you invested. So, if you invested 10, how much is 3 x 10? 30. If

[07:19] invested 10, how much is 3 x 10? 30. If you invested 100, 300. If you invested 1000, 3000. In other words, when you get a dozen or column right, regardless of which dozen or column it is, it will return three times the value. That is, when

[07:32] we put in R$50, like I was doing, times 3, it returns 150, which were the values. So, I was winning, right, 150. However, there's a catch: if I got one dozen right, I got the other wrong, right? In other words, from the 150 I win, I have to

[07:47] subtract the 50 I got wrong, right? Because if one I got right, which will come back three times, and the other I got wrong. So I have to subtract that. I also have to subtract the amount I

[08:00] subtract the amount I bet, because when you play bet, because when you play there, it's not all profit; there's the part of what I bet that comes back to me. So, if I put in R$100, I

[08:12] 'll win 100, but it's not 100 in profit; I 'll get back 100. The R$50 I bet plus the R$50 in profit, right? So, 150, right? Minus the 50 from the dozen I got wrong, minus the 50 from the dozen... So, I got it right, it came back to me, right? That leaves

[08:28] 50 minus the R$5 for the zero. Remember I protect the zero? Look, in this case, I have R$ 45 in net profit. So, that's my net profit, right? But what I was wrong. Normally, what do people do? When you're wrong,

[08:42] have any profit. I'll even end up with a loss. Why? Let's see. loss. Why? Let's see. I made a bet of R$105, right? 105, 50 on each pair and five on the zero. If I double down, how much will I bet on the chip

[08:59] ? Instead of betting 50, I 'll bet R$100 on each dozen. 100, 100 plus the 10 for the zero, because I doubled the zero too, right? The R$5 for the zero became 10. 210, right? When I get a dozen right or Okay, so what's

[09:14] going to happen? I have R$100. Remember I doubled R$100? Remember I doubled R$100? What's going to happen? 100 x 3, because it pays What's going to happen? 100 x 3, because it pays times 3, equals 300, right? But, remember

[09:28] that number? I have R$300, it came back 300. But I have to remember the first bet I made, which was 110, right? And the second one, which was 220. right? And the second one, which was 220. So, that would be R$315, right? R$315

[09:43] of investment. But when I win by doubling, what happens? It will only give me back R$300, meaning I'll be R$15 at a loss. So, if I'm wrong and double, it will give me back 300. I recover R$ 300 and I'm left with that R$15 loss.

[09:57] Did you understand? So, to make a profit, you have to triple it, okay? Okay? So, let's say I'm going to invest 315, right? Let's suppose I get it right, what happens if I triple it? I was entering with 50 chips, remember? I'm

[10:12] going to triple it. How much will it be in each dozen? It closes at 150, right? each dozen? It closes at 150, right? 150 x 3 equals 450. Then I'll have a profit, right? Then I'll have a profit. So, guys, it's a kind of... I

[10:26] can't explain it properly, but I think you understand. very high success rate because you'll be marking many numbers. However, if you're wrong, you'll lose a lot because you'll have to invest a lot

[10:38] to win little, you understand? It works for some , it doesn't for others. It works for me , I don't know, because I made this video to show you and I don't for 10 days to know if it's right or not. If you play in columns or dozens...

[10:51] comments. If you know any good strategies, leave them in the comments and okay? We're in this together, guys. Yeah, us. I hope you understood, can explain it better. If

[11:04] it, guys. I just know that in this video I made R$175 in profit playing Colon dúia. That's enough to live on, huh? We're in this together, guys. Yeah.
