How to Use the Kavouras Betting Strategy

Ioannis Kavouras a Greek mathematician designed the “Kavouras betting strategy”.

To use the Kavouras betting system in online roulette, follow these steps:

  • Place 20 chips on 20 different numbers.
  • Bet 1 chip on the following numbers: 0, 8, 11, 23, and 30.
  • Place a split bet (2 chips each) on the following splits: 31/32, 19/22, 18/21, and 8/11.
  • Place a corner bet (2 chips each) on the following corners: 25/26/28/29 and 17/18/20/21.

I keep my sessions short when playing roulette for real money. That ensures I don’t “overstay your welcome” because it’s a game of chance.

Results Over 10 Spins?

Over 10 individual spins using the Kavouras system, results will vary due to the random nature of roulette. Here’s what to expect:

  • Wins: You have a higher chance of hitting winning numbers because of the wide coverage. On average, you might win 3-5 spins out of 10.
  • Losses: Expect to lose on some spins, as no strategy can guarantee consistent wins in roulette.
  • Payouts: Wins will be moderate due to the balanced betting approach, which offers steady, smaller payouts.
  • Overall Outcome: You may experience a mix of small gains and losses. There is potential to break even or to make a small profit.

How Did It Go?

Bet Type Numbers Covered Odds of Winning Payout Results
Single Number 0, 8, 11, 23, 30 1 in 37 (2.70%) 35:1 Hit rate: 5 times
Split Bet 31/32, 19/22, 18/21, 8/11 2 in 37 (5.41%) 17:1 Hit rate: 5 times
Corner Bet 25/26/28/29, 17/18/20/21 4 in 37 (10.81%) 8:1 Hit rate: 5 times

The results from previous simulations encouraged me to test the Kavarous system by playing roulette for free.

My bankroll was £1000 and my average bet per spin was 1 unit over 50 spins.

I placed 20 chips on each spin, betting on various single numbers, splits, and corners.

The hit rate was 30% winning 15 of the 50 spins, resulting in returns of around 315 units. Given the total bet of 1000 units, I had a net loss of £685.

Thus leaving me with 315 units from the original 1000 units after 50 spins. As you can see, despite covering many numbers I “lost a lot of money”.

Pitfalls of the Kavouris Bet System?

The Kavouras betting strategy has several pitfalls. Despite broad coverage, my net loss was 685 units over 50 spins.

The house edge in roulette means no strategy can consistently overcome it. The game’s randomness can also result in unpredictable outcomes.

Placing 20 chips per spin depletes your bankroll quickly, especially during losing streaks.

Therefore, the strategy’s wide coverage might give a false sense of security without ensuring adequate returns.

Which Roulette System is Better: Kavouras or Martingale?

The Martingale system might be better if you play roulette for high stakes.

A larger bankroll can handle the risk of doubling bets after each loss which could recover losses quickly.

The Kavouras betting strategy offers a more moderate approach with lower risks per spin but doesn’t guarantee significant returns.

No matter how good both systems look on paper they’ll never overcome the house edge in the long run.


The Kavouris is not the best betting system for playing roulette because it favours the house the longer you play.

Despite playing with free credits I still lost £685 which is a large chunk of cash. Based on my playing experience, the Kavouras offer a 54% chance of winning.

That means you can still make a small profit if you use it over the short term. The longer you play the more money you’ll lose.

Aside from the Martingale, it’s better to use the 3/2 betting strategy as it offers 59.46% to 70.27% winning chances.

Even the Makarov-Biarritz offers odds of 62% to hit your winning number.

The Kavouras didn’t earn me a profit it’s still a popular system. Would I use it to play roulette for real money?

No, I won’t because other roulette betting systems offer me better odds of winning.


Which roulette variant is the best to use the Kavouras?

Use the Kavouras betting system to play European Roulette. It has a single zero, resulting in a lower house edge of 2.7% compared to American Roulette’s 5.26%.

For best results how long must I use the betting strategy?

The testing phase pointed out that even 50 spins is too long. To give yourself a chance of winning use the Kavouras system for at least 20 spins.
