The Street Bet in roulette is an Inside Bet on 3 numbers which pays out 11 to 1 if you win (you also get your original bet back). It’s also called Transversale Plein in French roulette. This is an “Inside Bet” (like the Split Bet and the Corner Bet) because you place your chips “inside” the number zone on a roulette table.
Well, it’s on the edge really, but it is categorised as an Inside Bet. It’s also known as a Row Bet or a Line Bet (but not to be confused with the Six Line Bet). A “street” is a line of 3 numbers on roulette tables.
An example would be a bet on 10,11,12 or 28, 29, 30. To place a Street Bet, place your chip at the end of a row of 3 numbers as shown above. You can use these kinds of bets in the 3 Quadrant Strategy. (資料來源 )
Bet on multiple streets to cover more table. This will allow you to mix it up a bit, rather than always betting on larger outside bets like Red or Black. If you bet on 6 streets, you will cover just under 50% of the table (remember there is also a zero pocket), and this will allow you to randomise your bets from spin to spin. If you place a Street Bet on a European Wheel, you have a 3:37 chance of winning (8.1%) or 1:12.3. On an American Wheel, your odds are 3:38 for each Street Bet (7.9%) or 1:12.7.
The difference between the odds and the payout is the house edge. If you want to cover more numbers, but don’t want to go up to a six-line bet, you can cover 4 with the Finales en Plein bets. or make a Corner Bet. (資料來源 )
