The Martingale is the most popular betting system in the world. It is also called the “doubling-up system” and can be applied to any even money bet. When playing a casino game, the amount of the first bet is simply doubled after each successive loss, until one wins. After each win, the bet is reduced to its initial value and remains there until the next loss. When one wins, one wins one unit. For example, an 11-step martingale would be : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 = 2047 units. That is a large amount to risk simply to win one unit ! Read More about Martingale System Here
If you use this strategy for a casino game such as roulette, craps or at sports betting, the danger is that eventually a long string of losses will keep increasing the amount of your bet until the table limit or the betting limit is reached.
Even with a low winning percentage of 30% and a long losing streak of 10-15 in a row, you’ll still be a winner! That is why I call it “the unbeatable sports betting system”.
We will use a modified martingale. We will start by betting the amount to win our target. We will be doing this until a win. If we win our first bet, we start over again. If we don’t win our first bet, we will bet the sum of the first 3 bets. So a win will erase 3 loses. Every time we lose, we keep betting for the same target. Only when we win, we will bet the sum of the first 3 bets (remaining bets). With this system, when we lose, we go one step backwards, and when we win we go 3 steps ahead.
Bankroll: I can’t tell you exactly what bankroll you need because the odds are changing everyday. But I think that a bankroll of 200 units would be reasonable.
The bet size will be calculated with the odds offer by the bookmakers.
The formula is: B = T / (IT-1)
- B = Amount to bet
- T= Target (amount you want to win)
- IT= International odds
Let’s say you want to win $50 at 2.20. $50 / (2.20-1) = $50 / 1.20 = $41.66 L-L-L-W-L-L-W-W
Here’s how it works: You need to bet $41.66 to win $50. $41.66 X 2.20 = $91.66 – $41.66 = $50
Let’s see what happen with a 37.5% winning rate and a target of $50.
Write down your target of $50 you want to make. You bet $54.95 to win $50 The odds are 1.91 You lose. Write down the $54.95 bet next to the $50 you had written down. It should look like this. $50 + $54.95 Day 2
The odds are 2.15 When you lose, your target still the same. So, here it’s $50 again. Your next bet is TARGET / (2.15 – 1). So it’s $50 / 1.15 = $43.48 You should bet $43.48 You lose.
Write down the $43.48 bet next to the previous two bets. Now it looks like this. $50 + $54.95 + $43.48 147
The odds are 1.83 You lose. Write down the $60.24 bet next to the previous three bets. Now it looks like this. $50 + $54.95 + $43.48 + $60.24 Our target is the same until a win. Your next bet is TARGET / (1.83 – 1). So it’s $50.00 / 0.83 = $60.24 You should bet $60.24
The odds are 2.10 Your next bet is TARGET / (2.10 – 1). So it’s $50.00 / 1.10 = $45.45 You should bet $45.45 You win. Cross out the first target you have written down. You do this (cross out the target) only after a win. That leaves you with the $54.95 bet, the $43.48 bet and the $60.24 bet. Now it looks like this. $50 + $54.95 + $43.48 + $60.24
The odds are 1.99 After the first win, the new target is the sum of the first three numbers we have written down. In our case we have $54.95, $43.48 and $60.24. So, our next target is $158.67. The next bet is TARGET / (1.99 – 1). So in our case it’s $158.67 / 0.99 = $160.27 Your next bet should be $160.27 You lose. Write down this bet next to the previous three bets. It looks like this. $54.95 + $43.48 + $60.24 + $160.27 148
The odds are 1.75 Your next bet is the TARGET / (1.75 – 1). So it’s $158.67 / 0.75 = $211.56 Your bet should be $211.56 You lose. Write down this bet next to the previous four bets. $54.95 + $43.48 + $60.24 + $160.27 + $211.56
The odds are 2.45 Your next bet is the TARGET / (2.45 – 1). So it’s $158.67 / 1.45 = $109.43. Your bet should be $109.43. You win. Cross out the first three bets (OUR TARGET). That leaves us with… $54.95 + $43.48 + $60.24 + $160.27 + $211.56 Day 8 The odds are 1.90 You win. The session is over. You have recovered from all your loses and made a $50 profit. Your next target the sum of the two remaining bets / (1.90 – 1). Since we don’t have 3 numbers written down, we bet on only the sum of the two remaining bets. So it’s $371.83 / 0.90 = $413.14 You should bet $413.14
You won 3 bets and lost 5 bets. Winning rate: 37.5%
