The Kavouras Roulette System, first introduced as the Four Pillars strategy, is a betting system devised by Ioannis Kavouras. This strategy, whose exact year of publication is not specified, involves a unique betting scheme that adds variety to gameplay and prevents boredom at the table.

The system is simple and easy to understand. Players place chips according to a specific scheme: 1 chip on the corner 0-1-2-3, 2 chips on the street 31-32-33-34-35-36, and 1 chip on each of the splits 8-11, 13-14, 15-18, 17-20, 27-30. It is important to note that this system does not affect the house edge.

One of the appealing aspects of the Kavouras System is that it can be tried for free in free games. Moreover, it can be used in real casinos and online roulette games, including Casino Bonuses, Vavada Casino, PlayFortuna casino, Riobet Casino, Jozz Casino, Booi casino, Cat Casino, Joycasino, Casino X, and Champion casino.

It is crucial to mention that the Kavouras System is not considered the key to beating roulette. When one of the numbers hits, the win is between one to ten chips. The system can be combined with any negative or positive progression system, but this doesn't increase its effectiveness.

Another advantage of the Kavouras System is that it doesn't raise suspicions with pit bosses, even those with acute paranoia. Furthermore, the system isn't tied to sectors and appears quite random, making it less likely to attract unwanted attention.

However, it is not recommended to play the American version of the Kavouras system due to the additional zero pocket. The author of the system seems to no longer be active on Roulette30.com, but the information for this article was taken from the site, as well as several international gambling forums.

In conclusion, the Kavouras Roulette System is a simple, easy-to-learn betting strategy that can add an element of excitement to your roulette gameplay. While it doesn't guarantee any specific wins or bonuses, it does provide some financial control and prevents boredom at the table.
