3/2 System Implementation
You need to employ a specific wager value for each of your simultaneous bets if you want to apply this approach. To put it plainly:
- Pick an even-money bet (low/high, red/black, odd/even) and wager three units.
- Split the cost of a column bet by two units (1st 12, 2nd 12, or 3rd 12).
It ends there. This mixture must be maintained throughout the approach. You have the freedom to select any column or an even money wager. (In the first round, you can choose the red/black option for the first column, and in the second round, you can choose the odd/even option for the second column.) You are free to utilize any combination you like within these bet kinds and wager amounts as the strategy specifies.

But remember that you can cover more outcomes with certain combinations. If you choose them, your chances will be significantly higher. This is due to the fact that various ranges of numbers are covered by even money and column bets (and colours). Putting them in a list will help you comprehend them better. The following outcomes are covered by column bets:
- Eight red and four black are arranged in the first column:: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36 (8 red and 4 black in total)
- Second column: 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35 (4 red and 8 black)
- Third column: 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34.... (six pairs of black and six pairs of red)
We are aware that a total of 18 numbers can be covered by even money bets. As a result, we can increase our odds of winning with specific combinations. The probabilities of various permutations are listed below:
Red + 1st column | 59,46% |
Red + 2nd column | 70,27% |
Red + 3rd column | 64,86% |
Black + 1st column | 70,27% |
Black + 2nd column | 59,46% |
Black + 3rd column | 64,86% |
The best winning combinations are "red + second column" and "black + first column," as is evident from this chart. When considering the possible rewards, though, "red + first column" and "black + second column" stand out as superior choices due to the greater number of intersections they provide and, thus, the higher payouts they offer. So that you may get it, allow me to explain it thoroughly:
- There are 8 numbers that cross in the "red + first column" combination, and the probability of winning is 59.46%.
- With 4 intersecting numbers, the "red + second column" combination has a 70.27 percent probability of winning.
- Every time two numbers cross, you'll get seven units as a reward. For all other numbers, the payoff is just one unit. Consequently, the payout is at least double for the "red + first column" combination.
A 3/2 Strategy Test We Conducted
Every roulette strategy we look at is tested in a simulation to evaluate how it performs in the short and long run. We set the parameters of these models according to what the plan calls for. We utilized the following settings for the 3/2 strategy:
- We divided the $1,000 money among three players.
- We made them each spin 500 times.
- We instructed them to optimize their reward possibilities by placing their bets based on the "red + first column" combination.
Keep in mind that this approach doesn't advocate for any particular combination; all it demands is that you wager even money and columns. Consequently, we were free to choose the combination that we wanted to utilize. In the figure below, you can observe the outcomes:

- After 500 spins, Player 1 had accumulated $1098. Earnings: $98
- The second player finished 500 spins with $1020 in their account. Making $20
- The third player finished the 500 spins with $858 in their account. Down $142
But the first results were intriguing: all three players turned a profit in the first fifty spins. Therefore, they would have all benefited if they had ceased playing. But we stuck it out for 500 spins since we were interested in the big picture as well as the short term; after all, the smart thing to do when you hit it big is to walk away from the table when you win. For the simple reason that every player loses in the end due to the inevitability of the math.
The 3/2 System's Drawbacks
In short-term game sessions, the 3/2 approach can be surprisingly effective and has no specific downside. The combination you use will determine how successful it is, though. Based on the parameters we set up for this simulation, we were able to determine:
- Our balance would be deducted by 5 units for every one of the fifteen eventualities that would lead to a loss.
- Our payouts increased by 7 units because 8 fields intersected.
- We achieved +1 unit payouts with 14 regular fields.
- In the first fifty spins, we turned a profit.
Changing the even money + column combination will yield various outcomes. Using the red + second column combo, for instance, would increase our winning frequency but decrease our profit. Any way you slice it, the 3/2 system is easy enough for a child to utilize, and it usually works.
In summary
The betting selections and bet amount remain constant in this flat betting system. You can increase your odds of winning from 59.46% to 70.27% by covering more or less of the table. Because of the variety of possible wagers, it can accommodate players with varying skill levels and financial resources. Plus, it's one of the simplest roulette strategies to implement.
Keep in mind that the RTP and house edge values will remain unchanged, despite these substantial benefits. Since this is a short-term strategy, you should cash out as soon as you start making money. If you keep playing after you've made a profit, you'll lose in the end since you can't beat the house edge. You may adjust the system to suit your demands, which means you should only use it for short sessions. You have the option to increase your winning odds or reward potential.
