The 6 Line Bet or Transversale Simple is an Inside Bet like the Single Number Bet or the Corner Bet (Square Bet). It's got nothing to do with the number 6 (although a 6 line bet can cover this black number).They are called Inside Bets, because of the layout of a roulette betting table. They all lie inside the main betting area (as opposed to outside bets like dozens and columns that lie (yes, you guessed it), outside! This bet is used in a number of roulette staregies like the Shotwell System. If you like this bet, you should also take a look at the Six Line Quattro roulette system which plays 4 of these bets.
This bet is made on two lines of three numbers each that lie next to each other: a total of six numbers. This bet is made by putting your chips on the intersection between the two lines along the side of the betting area. If any of these numbers hit, the the pay off is 5-1.
For example, above, we have 4 Six Line Bets above, covering 64.8% of the table (the same as 2 colums or 2 dozens. Don't confuse the 6 line bet with the Five Number Bet, which has the worst odds on the table. The 6 Line is a totally different animal.
If you place one 6 line bet on European Roulette, you have a 6:37 chance of winning (16.2%). 1 in 6.2 in other words.
If you play American Roulette, your odds are 6:38 for each 6 number bet or 15.8%. 1 in 6.3 is another way of putting it.
The House Edge on this bet is 5.26% for American Roulette (2 zero pockets) and 2.63% in European Roulette.
Roulette Strategies that Use the Six Line Bet
There are lots of strategies that use the six number bet. The simplest one, is a way of getting a bit of variation on the even money bets, which many systems like the Martingale and the Guetting Progression use. Instead of playing red/black, odd/even etc, you cover 50% of the table using 3 out of the 6 available 6 line bets. You can either overap them to reduce your table coverage, or play exclusive 6 line bets (that don't overlap) to get the full 50% coverage. Sometime we like to cover the table this way, as it allows you to vary your coverage bet by bet. It doesn't improve your odds (still the same house edge and chance of winning), but it does "randomize" your play.
You can also just bet on 2 six-liners to cover the same as a column or dozen, of course. This allows you to vary some of the systems that use these bets like the Law of The Third for example. If you want to mix it up even more, use Street Bets which is a bet on one row of 3 numbers, rather than 2 rows.
This is a bet that every casino should have available. Play it on a European Roulette Wheel as the odds are better. We'd recommend European Roulette Gold. Get a £100 bonus at Bet365 at the moment on this variant.
