Fractional Betting System

Introduction to the Fractional Betting System

The Fractional betting system is a strategic approach to gambling that can be applied to games of chance like Blackjack, Baccarat, and Roulette. It’s designed to capitalize on the natural ebb and flow of winning and losing streaks, allowing players to adjust their bets dynamically.


How the Fractional Betting System Works

At its core, the system is straightforward:

  • Two consecutive wins or losses signal the start of a trend.
  • Adjust your next bet based on this perceived trend.
  • Maintain a mix of chip denominations for flexible betting.


Adjusting Your Bets

Here’s how to modify your wagers:

  • After 2 wins: Increase your wager by 1/3 of the last bet.
  • After 2 losses: Decrease your wager by 2/3 of the last bet.
  • Continue this pattern, adapting to the game’s momentum.


Betting in Action: A Practical Example

Consider this betting sequence to understand the system better:

  1. Start with a bet that’s three times the table’s minimum.
  2. After a win, increase the next bet by one-third.
  3. Following a loss, increase the next bet by one-third, anticipating a win.
  4. If another loss occurs, decrease the next bet by two-thirds.
  5. Continue with these adjustments as the game progresses.


Personal Insights and Alternative Strategies

While the Fractional betting system has served me well, particularly in Blackjack, it’s not a one-size-fits-all solution. Some may find it less effective, and in those cases, exploring other strategies like the Small Wins system, Stan’s system, or the Star Alternative progression system could be beneficial.



The Fractional betting system is a nuanced approach that requires discipline and attention to the game’s flow. It’s not about chasing big wins every time but rather maintaining a steady course and capitalizing on the right moments. As with any betting strategy, it’s essential to understand that results can vary, and what works for one may not work for all.
