Double Street Quad Roulette System Explained

The Double Street Quad System is a betting strategy that covers 17 numbers on the roulette wheel.

It initially sounds like a complicated approach, but it is actually very simple. Read on to learn how the Double Street Quad System works and why it is popular with roulette players.

What is the Double Street Quad System?

The Double Street Quad System is a roulette strategy for betting that requires you to place four separate bets before spinning the roulette wheel:

  • Two double street bets (2 units each)
  • A corner bet (1 unit)
  • A straight-up bet on a single number (1 unit)

That means you wager 6 units in total. This approach covers 17 numbers, which gives you a 17 in 37 chance of success when you play European Roulette or French Roulette. It goes down to 17 in 38 if you play American Roulette, which has a double zero.

However, the bets—double street, corner, and single number—have different payout rates, which adds a degree of volatility that some players find appealing.

This betting system works in any roulette format. Whether you are playing in person, betting with an online real money casino, experiencing roulette in a live dealer setting, or simply playing roulette for free.

What are the payout rates when using the Double Street Quad?

The Double Street Quad roulette betting system breaks down into three parts.

Double Street Bet

A street bet covers three numbers. They go across the board, such as 1-2-3, 4-5-6, or 7-8-9.

A double street bet requires you to lay your chips over two adjacent streets, meaning you cover six numbers. For example, you could bet on the numbers 1-6 or the numbers 4-9.

Place two separate double street bets on separate parts of the board, covering 12 numbers in total. Each double street bet should be for 2 units.

If a double street bet wins, it pays out at 5:1. That means you will win 10 units from a 2-unit bet. That provides a net gain of 4 units, as you wagered 6 units on the Double Street Quad.

Corner Bet

A corner bet simply requires you to lay your chips on the corners of four numbers clustered together on the board. Place a 1-unit bet on the corner.

If the ball lands on one of the four numbers you have covered, you will be paid out at 8:1. It will earn you 8 units, resulting in a 2-unit gain.

Single Number Bet

Lay your chips down on any single number that you have not yet covered with your double street or corner bets. This is another 1-unit bet.

If the ball lands on that number, you will be paid out at 35:1, resulting in a 29-unit gain.


Let’s say you have a $500 bankroll, and you make 2% your base unit ($10). You might then place these bets:

  • $20 on a double street covering 1-6
  • $20 on a double street covering 16-21
  • $10 corner bet on numbers 8, 9, 11 and 12
  • $10 bet on number 36

That means you have covered 17 numbers in total: 1, 2, 3, 4, 5, 6, 8, 9, 11, 12, 16, 17, 18, 19, 20, 21, and 36. There are four potential outcomes:

  • The ball lands on 1, 2, 3, 4, 5, 6, 16, 17, 18, 19, 20 or 21, and you earn a $40 profit.
  • The ball lands on 8, 9, 11, or 12, and you earn a $20 profit.
  • The ball lands on 36, and you earn a $290 profit.
  • The ball lands on any other number, and you lose $60.

You can repeat this process as many times as you like. Most online roulette games offer a “Repeat Bet” option, so you will not need to go through the rigmarole of laying all your chips down before each spin.

Why you might like the Double Street Quad System

  • It may appeal to players who want to cover lots of potential outcomes while also offering the possibility for a big win if the straight-up single number pays off.
  • There are several different potential outcomes when you follow this approach, which may attract players who grow tired of the binary side bets like red/black and odd/even.
  • You will never run up against table limits, as you only place 6-unit bets each time.

Drawbacks to the Double Street Quad

  • It can require a large bankroll.
  • Your net gain will only be 67% of your 6-unit risk amount if a double street pays off and 33% of your risk amount if the corner bet pays off, whereas you double your money on successful red/black, odd/even, or high/low bets.
  • You only earn the maximum benefit if your individual number bet pays off.
  • Roulette has a house edge, and the Double Street Quad strategy for roulette cannot overcome that.

Other Roulette Betting Systems

The Double Street Quad System for roulette is a fine system to use, but it is far from the only one out there. Some of the more famous ones include:

Like many casino game strategies, the Double Street Quad System doesn’t guarantee success, as it cannot change the fact that there is a house edge built into the roulette wheel. It can lead to short-term success if you are lucky and the ball lands on the individual number you have selected, but the results are random, and the Double Street Quad cannot influence them. This is true for any roulette system.

The Double Street Quad requires two double street bets, a corner bet, and an individual number bet. Place 2 units on each of the double street bets and a single unit on the other two bets, resulting in a total risk of 6 units.

Absolutely—both for online and land-based roulette.

This system requires you to place two double street bets and a corner bet, which is also known as a quad bet. It features a single number bet, too, but the creator may have decided that “Double Street Quad Single” was too much of a mouthful.

The Double Street Quad is a reasonably appealing approach for players who want to spread out their risk. However, it requires a reasonably large bankroll, and it does not guarantee you will win.
