The Fibonacci betting system is your secret weapon for determining how much to stake in popular casino games like online blackjack, roulette, baccarat, and more. As a negative progression strategy, it’s designed to increase your stake after each loss, but don’t worry—it’s safer than other high-risk systems like Martingale, with plenty of room for big rewards.

About the Fibonacci Betting System

Leonardo Bonacci, otherwise known as Fibonacci, was an exceptionally brilliant mathematician from the Middle Ages who is famous for bringing the numeral system to Europe and establishing the so-called Fibonacci sequence.
His sequence, used to model rabbit population growth, forms a series where each number is the sum of the previous two, starting with 0 and 1 (0, 1, 1, 2, 3, 5, 8, 13, and so on).
Fast-forward to today, and the Fibonacci betting system is sitting pretty among the most popular casino betting systems! In this strategy, you apply the sequence in determining how much to bet on even-money bets, such as red/black or odd/even in roulette.
Here’s how:
- Start by setting aside a bankroll (preferably no more than 5% per base unit). For example, with $500, you’d bet $10 (2% of your bankroll) on your first wager.
- If you win, start over with $10. If you lose, move up the sequence: 1-1-2-3-5, etc.
- Keep climbing the sequence after each loss, and after a win, move back two numbers.
Repeat this pattern as you play, and soon enough, you’ll be using Fibonacci’s legendary sequence to level up your betting game!
How to Use the Fibonacci Betting System in Casino Games
Fibonacci Blackjack Betting System

- Set your bankroll: Choose a base unit based on your Blackjack bankroll. For example, if you have $250, you might pick $5 as your base unit.
- Start betting: Place your first bet with $5 (1 unit). If you win, go back to the starting point and bet $5 again.
- Move up with losses: If you lose, move forward in the sequence. The sequence is: 1-1-2-3-5-8-13-21… So if you lose your first bet, bet $5 again. If you lose again, bet $10, then $15, $25, etc.
- After a win: Once you win, move back two places in the sequence. For example, if you won at $40, your next bet would be $15.
12BET Casino Tip: For huge profits using the Fibonacci betting system for Blackjack, land five consecutive wins, especially when deep in the sequence!
Fibonacci Roulette Betting System

- Focus on 50/50 bets: Stick to bets like red/black, odd/even, or 1-18/19-36. These Roulette bets offer the best odds for applying the Fibonacci betting system.
- Choose your base unit: Decide how much you want to risk per spin. For example, you might choose 0.33% to 5% of your bankroll. If your bankroll is $200, your base unit could be $1 or $10, depending on your risk tolerance.
- Bet and move up: Place your first bet on, say, red. If it wins, go back to the beginning of the sequence. If it loses, move to the next step in the Fibonacci sequence (1 unit → 2 units → 3 units → etc.).
- Adjust for losses: Keep ramping up your bet with each loss until you win, at which point you move back two steps in the sequence.
12BET Casino Tip: Make sure to check the betting limits before starting. Some games have maximum bet limits that might prevent you from following the sequence after a losing streak.
Fibonacci Betting System for Baccarat
- Select your bet: Baccarat offers two main betting options with low house edges: banker (1.06%) and player (1.24%). Stick to these bets for the best results.
- Set your base unit: Choose a base unit based on your bankroll. If you have $200, you could bet $2 to $5 per round.
- Follow the sequence: Start with your base unit bet. If you lose, move forward in the Fibonacci sequence (1-1-2-3-5-8-13…). For example, if your first $2 bet loses, your second bet would still be $2. After another loss, increase to $4, then $6, and so on.
- After a win: When you win, move back two steps in the sequence. For example, if you win at $6, your next bet will be $2.
12BET Casino Tip: Avoid betting on the tie bet, as it has a much higher house edge (14.4%) and doesn’t fit well with the Fibonacci betting system.
Fibonacci Craps Betting System

- Pick 1:1 bets: Craps has many betting options, but the Fibonacci system works best with 1:1 bets such as pass, don’t pass, come, or don’t come.
- Choose your base unit: Let’s say you have a bankroll of $10,000 and decide to use 2% of it as your base unit, which would be $200.
- Bet and move up: Place your first bet (e.g., $200 on pass). If you win, restart the sequence with your base unit. If you lose, move to the next number in the sequence (1 → 1 → 2 → 3 → 5…).
- After a win: When you win, move back two steps in the sequence. For example, if you win after betting $400, your next bet would be $200.
12BET Casino Tip: Like roulette, make sure you’re comfortable with the limits of the game when using the Fibonacci betting system. If your bets grow too large, you may hit the table’s max bet.
