‘High-Low Bet’ Meaning | Casino & Gambling Terms Explained

A High-Low Bet is a type of outside bet in roulette that covers either the low numbers (1-18) or the high numbers (19-36) on the wheel. It is also known as a Manque Bet (low) or a Passe Bet (high) in French roulette. A High-Low Bet pays 1:1, which means you win the same amount as you bet. The probability of winning a High-Low Bet depends on the variant of roulette you are playing. In European roulette, the chance of winning is 48.6%, while in American roulette, it is 47.4%. This is because the American wheel has an extra 00 pocket that reduces the odds of landing on a low or high number.

High-Low Bet in Roulette

A High-Low Bet is a simple and popular bet that appeals to many players because it covers half of the numbers on the wheel (except the zero or double zero). It is also easy to place on the table, as it has a designated area for each option. A High-Low Bet can be combined with other bets, such as red/black or odd/even, to increase the chances of winning or to create a more complex betting pattern.

However, a High-Low Bet also has some disadvantages and risks. A High-Low Bet has a low payout compared to other bets, such as a single number bet that pays 35:1. A High-Low Bet also has a high house edge, which means the casino has a greater advantage over the player in the long run. A High-Low Bet can also be affected by the rules of the game, such as the La Partage or En Prison rules in French roulette, that can either benefit or harm the player depending on the outcome.

A High-Low Bet is a basic but effective roulette bet that can be used with different strategies and systems. Some of the strategies that can be applied to a High-Low Bet are:

  • The Martingale System: This is a progressive betting system that involves doubling your bet after every loss until you win. The idea is to recover all your previous losses and make a profit equal to your initial bet. For example, if you bet 10 GBP on low and lose, you bet 20 GBP on low and lose again, you bet 40 GBP on low and win, you get back 80 GBP, which covers your 70 GBP loss and gives you a 10 GBP profit. However, this system is very risky, as it requires a large bankroll, a high betting limit, and a lot of patience. It can also lead to huge losses if you encounter a long losing streak.
  • The Fibonacci System: This is another progressive betting system that involves following a sequence of numbers that is based on the Fibonacci sequence. The Fibonacci sequence is a series of numbers that starts with 1 and 1, and each subsequent number is the sum of the previous two numbers. For example, 1, 1, 2, 3, 5, 8, 13, 21, and so on. The idea is to move one step forward in the sequence after every win, and two steps back after every loss. For example, if you bet 1 GBP on low and win, you bet 1 GBP on low and lose, you bet 1 GBP on low and lose again, you bet 2 GBP on low and win, you bet 1 GBP on low and win, you bet 2 GBP on low and so on. This system is less aggressive than the Martingale system, as it increases the bets more slowly, but it still requires a large bankroll and a high betting limit to work effectively.
  • The D’Alembert System: This is a balanced betting system that involves increasing your bet by one unit after every loss, and decreasing it by one unit after every win. The idea is to reach a point where your wins and losses are equal, and you make a profit equal to the number of bets you placed. For example, if you bet 10 GBP on low and lose, you bet 11 GBP on low and lose again, you bet 12 GBP on low and win, you bet 11 GBP on low and win, you bet 10 GBP on low and lose, you bet 11 GBP on low and win, you have placed 6 bets and won 3 of them, and you have made a profit of 6 GBP. This system is less risky than the progressive systems, as it does not require a large bankroll or a high betting limit, but it also has a lower potential for profit.
