James Bond Betting System for Roulette

Last updated: 03.13.2023 by Andrew Shepard

We can roughly divide roulette strategies into two groups: those that focus on bankroll management and those that want to increase your chances of winning. Bankroll management strategies do not care about how lucky you are and aim to make profits at a certain point by placing your wagers according to a certain system. Strategies for the chance to win try to cover as many outcomes as possible and some of these may seem quite logical at first glance.

James Bond betting strategy is one of them. It first appeared in Ian Fleming's book 'Casino Royale' published in 1953. Fleming wanted to develop a system that readers could easily understand and follow. Using this strategy, James Bond managed to defeat the 'bad guy'. But what made this strategy famous was the 1971 Bond movie ‘Diamonds are Forever.’ In the movie, Sean Connery used this system to leave the roulette table with a bag full of money. And no, the 2006 movie ‘Casino Royale’ didn't use the roulette game: Daniel Craig preferred to play poker against the villain, unlike in the book. We can say that it was Sean Connery who made the James Bond roulette system famous.

So, it is not surprising that James Bond roulette strategy has seriously interested many inexperienced players or those who have not played roulette at all. It is logical to assume that the author and the film directors who invented this system had only a symbolic meaning, and its real effectiveness is doubtful. However, let's all understand how the James Bond strategy works, conduct a test and formulate the final verdict.

How James Bond Strategy Works

So, the idea behind the James Bond roulette system is quite simple. It is not a progressive system, and the same combination is put on each move:

  • 14 units at 19-36(high)
  • 5 units per six-line (13, 14, 15, 16, 17, 18)
  • 1 unit per 0
James Bond Strategy

Thus, there are 4 possible outcomes of each round in the James Bond method:

  • The 19-36 bet wins: the profit will be +8, and the probability is 48.65%
  • The six-line bet wins: profit +10, probability 16.22%
  • Zero Wins: profit +16, probability 2.7%
  • Not a single bet wins: profit -20, probability 32.43%

Our test of the James Bond System

Finally, we will demonstrate the effectiveness of James Bond betting strategy in the long run. To do this, we will build a game simulation based on a given mathematical model: we know 4 possible outcomes of each round and the probabilities of these outcomes. Thus, we can simulate a game with a duration of 1.000 spins. Let the starting bankroll be $1,000, and for the purity of the experiment, let's add 5 players. We will build a graph of changes in their bankrolls over 1.000 spins.

Fisher system to the Test

According to the James Bond strategy, this graph shows that the course of the game can take a very different approach. Take, for example, the most successful case - Player №1 - his bankroll peaked on the 387th move and amounted to $1,454. The rest of the players turned out to be less lucky and only went into a small profit at the beginning of the game.

Previously, we tested various more or less well-known strategies, and it cannot be said that the James Bond roulette system is somehow superior to them. Also, it should be reiterated that the James Bond method is only part of the scenery for the film's plot, and it doesn't have to be effective. While the strategies invented by the players have at least some rationale.

Pitfalls of the James Bond Method

Why this system cannot be profitable can be easily proved mathematically. Above, we have described the possible outcomes of each game round. So, for 1,000 spins, according to statistics, the profit will be:

486*8 + 162*10 + 28*16 -324*20 = -524

Thus, this system does not break the house's edge.


First of all, people who are interested in the James Bond strategy should not take it seriously, as it was made up by the filmmakers for a beautiful movie and has no mathematical justification for success.

There are many other roulette strategies that are much more logical and effective. We have tested some of them and recommend that you familiarize yourself with them.

Like it or not, you can't fool house edge, and the James Bond scheme is no exception. So, for 1000 moves, on average, your loss will be -524 units.
