In roulette, a street bet is a bet of three numbers placed at the outside line at the edge of the row as shown in the image. It´s also called Transversale Plein in French roulette and also known as a Row Bet or a Line Bet (but not to be confused with the Six Line Bet). If one of the numbers in the street bet comes up, the player gets 11:1 for the win. If you place a Street Bet on a European Wheel, you have a 3:37 chance of winning (8.1%) or 1:12.3. Of course you can bet on more than one Street at a time up to as many as you wish.

All of the following data refers to Single Zero Roulette. In our first Analysis we want to know how many streets we can expect to hit in 12 consecutive spins. According to the Law of the Third which of course can be applied to the Street Bet too, we would expect that on average 2/3 of the 12 Streets get hit and about one third does not get hit. That is eight Streets get hit and four Streets do not get hit. We are not only interested in the average hit ratio but also in the distribution of the actual results. In the table and the graph you can see how often a certain number of Streets get hit or not hit in 12 consecutive spins in 60.000 trials.

It does not happen that only 1, 2 or 3 Streets get hit within 12 spins. But in 0,1% of the trials only 4 different Streets get hit within 12 spins. In 2,1% of the trials 5 different Streets get hit and so on. Mostly, that is in 33,9% of the trials, 8 different Streets get hit within 12 consecutive spins. On the other hand we see in the 3rd column of the table and displayed in red in the chart that in 33,9% of the trials 4 Streets do not get hit in 12 spins. Of course a perfectly mirrored match of the data in the 2nd column and blue line in the chart.

No of Streets | Hit [%] | Not hit [%] |

1 | 0,0 | 0,3 |

2 | 0,0 | 3,7 |

3 | 0,0 | 17,6 |

4 | 0,1 | 33,9 |

Now we want to see how often the Street with the highest hit score in 12 consecutive spins gets hit. Again we test 60.000 trials of 12 Live Dealer spins and get the following results. It does not happen, that the maximum hit score is 1 hit (1x) only. In 34,6% of the trials the maximum hit score of one or more Streets is 2x. Mostly, in 50,6% of the trials, the maximum hit score of one or more Streets is 3x. The highest hit score of a certain Street in 12 consecutive spins is 6x. That happens in 0,2% of the trials only.

Since most of the time we see at least one Street that gets hit 3x in 12 consecutive spins we want to know how many consecutive cycles of 12 spins we can fail to see a Street to hit 3x. The test results show that it can happen up to 11 cycles of 12 spins. But mostly, in 66,06% of all trials, we will fail to see one or more Streets to get hit 3x for 1 cycle only. In 21,79% of the trials we have 2 losing cycles before we see a 3x in the very next 12 spins again.

Length of Losing Streak | Count | Occurance [%] |

1 | 8979 | 66,06 |

2 | 2960 | 21,79 |

3 | 1048 | 7,71 |

4 | 403 | 2,97 |

5 | 123 | 0,91 |

6 | 53 | 0,39 |

7 | 11 | 0,08 |

8 | 5 | 0,04 |

9 | 3 | 0,02 |

10 | 1 | 0,01 |

11 | 1 | 0,01 |

In our next test we want to check when we can expect to see a Street to get hit 3x. That is in other words: At which spin does any Street get hit for the 3rd time (3x). In this test we cycle through as many spins as necessary to get the first 3x Street in 1 Million Live Dealer spins. The results form a nice bell curve with its peak at spin 10. We see that the first Street gets hit 3x for 4015 times (in 10,4% of the trials) at spin 10. In 3987 trials (also 10,4%) the first 3x hit Street occurs in spin 11. In only 1 trial it takes 24 spins for a Street to get hit 3x and in 271 trials it takes only 3 spins for a Street to get hit 3x.

Spin | Occurance | Occurance [%] |

1 | 0 | 0,0 |

2 | 0 | 0,0 |

Now we want to know how often the first 3x hit Street arises out of how many 2x hit Streets in 12 consecutive spins. The results show that mostly (37,0% of the trials) there are 2 Streets that have hit 2x before one of them gets hit a 3rd time. In 31,7% of the trials the first 3x hit Street requires only 1 Street to have hit 2x and in 23,9% of the trials it takes 3 Streets to hit 2x before one of them gets hit 3x.

In our last test we check the amount of 2x hit Streets in case there is no 3x hit Street in a 12 spin cycle. We test 60.000 trials of 12 consecutive spins again. The results show that mostly, in 8498 cycles without any Street hitting 3x (40,9%) there are 3 Streets that hit 2x. In 31,3% of the cases without a 3x hit Street there are 4 Streets that hit 2x and so on.

Amount of 2x Hit Streets | Occurance | Occurance [%] |

0 | 22 | 0,1 |

1 | 574 | 2,8 |

2 | 3757 | 18,1 |

3 | 8498 | 40,9 |

4 | 6486 | 31,3 |

5 | 1386 | 6,7 |

6 | 30 | 0,1 |

Based on that knowlege you can create several systems for Street Bets.
