A historic roulette player named Charles Wells developed a betting system called the Wells Pendulum system, otherwise known as the swing betting system. This particular system works best when applied to even money bets in the game of roulette.
Swing betting is one of the oldest betting systems out there and its complex nature doesn’t exactly make it as popular as some of the other betting systems out there. But, we believe it’s still worth knowing about so we’ve dedicated this guide to discussing all there is to know about this betting system. So, if you would like to know more about the system and how it works, continue reading.

Swing Betting in Roulette
This theory compares the probability of even money bets occurring in roulette to a swinging pendulum. Wells suggested that even money bets in roulette i.e. red/black, odd/even, and high/low would hit more or less the same number of times on either side of the pendulum.
Imagine a pendulum placed in the middle of two sets of coloured numbers that include red on the one side numbered 1-10 and black on the other side numbered 1-10. During a perfectly controlled experiment you would expect the pendulum to hit red, then swing to black and back to red and so forth. This kind of experiment is most likely to produce equal results for both red and black. Meaning the pendulum hit either side the same amount of times during a specific spin round.

How Swing Betting Works
In a real-life roulette game, the results aren’t likely to be as constant as in the controlled experiment above. How the ball rolls is based on chance which makes it unpredictable. So, during a round of roulette, one colour is likely to come up more than the other. So, red might have come up 7 times while black only came up 3 times during a specific round or time frame.
How you record this information also works a little differently. Using the example of 7(black) and 3(red) during a 10-spin round, the score for this experiment would be recorded at 4 (black) because that’s the difference between the two. If black hit again then that would raise the score to 5(black). But, if red hit twice consecutively after that then the 5(black) score would drop to 3(black) and the new score would be 3(black), 2(red). The score is recorded like this until the round is over.
To effectively use the swing betting system, Wells suggested that your bankroll be as big as 145 units, and suggested that each bet amount consist of 10 units on whatever even money bet. How you carry out this system is similar to the D’Alembert betting system where you decrease your wager by one unit after every win and increase it by one unit after every loss.
Modified Version of The Pendulum System
To prevent the loss of units, the Wells Pendulum system was divided into two separate strategies overtime. The first strategy suggests that you begin by wagering 5 units and hope to secure five consecutive wins to take home a profit of 15 or more units. Thereafter the scheme will start over. Essentially this means that once you secure your number 5 win, you must reduce your bet amount to 4 units, then three, then two, then one provided you win each time. Once you get to zero you must quit. This strategy only needs a bankroll of about 45 units.
Alternative Betting Systems in Roulette
Swing betting is but one of the probable systems that you can use when playing online roulette. Many other systems exist and they include:
- The Paroli System
- Martingale System
- Fibonacci System
- James Bond
- Labouchere System
Play Casino Games for Real Money
Playing roulette for real money can be a risky ordeal which is why players resort to strategies and systems like this. But, despite the massive risk attached to it, using systems and strategies is the better way to play because you are making calculated moves instead of random moves just to get by.
When you are ready to play for real money you can visit any of the online casinos that we list in our table above. You can play roulette for free or real money, and every game is accessible on mobile and desktop.
