This article gives you a quick overview of the most well-known Roulette systems. Followed by a brief introduction of each system; click the link at the end to continue exploring it in a separate, more in-depth article.

Despite being an unbeatable game, Roulette systems exist because people think there are winning strategies out there that work. Roulette is a game of chance structured to ensure the house always has a long-term mathematical edge, also known as an advantage, over its' players by at least 2.70%.

## What is a Roulette system?

Also called a strategy, a Roulette system consists of three things; 1) An idea behind the system. 2) How to place your bets. 3) How to manage your bankroll.

*Although there is a logic behind any idea for a Roulette system, the math demonstrates that none can make you a winner long-term.*

European and American Roulette odds pay 35:1 when you hit a straight-up number. Still, the Roulette wheels have 37 (European variant) and 38 (American variant) pockets, giving the house a mathematical edge of 2.70% and 5.30% over you and an expected value of -€0.027 and -€0.053 per €1 you wager.

## The Martingale strategy

The Martingale system is a class of several betting strategies. The most famous among gamblers is the simplified Martingale, where you, after each loss, double your stake in hopes of winning the next round and recovering previous losses plus winnings equal to your last stake.

## The Oscar's Grind strategy

The concept of Oscar's Grind is that there are losing and winning streaks when playing even-money bets. The goal of Oscar's Grind is to either profit from a short winning streak immediately or hit a winning streak after a losing one, where the win compensates for losses. Like the Labouchère- and the Martingale systems, Oscar's Grind assumes you have infinite time and money when wagering to ensure profitable sessions.

## The Kavouras Bet

The Kavouras bet is a system made specifically for Roulette, making use of three different bets; "Corner," "Split," and "Six Line." The thought behind the Kavouras strategy's goal is to bet on as many numbers as possible for the least amount of units. Specifically, the combination of the different roulette bets covers 20 numbers and guarantees a minimum and a maximum profit of 1 and 10 if you hit.

## The Tier et Tout strategy

The Tier et Tout strategy aims to have a winning bet within two bets. The system plays out by starting with a predetermined amount you want to bet and one that can be divided by three. You start with a new amount if you lose two bets in a row. If you win the first or the second bet, you add the winning number to your starting amount and divide it by three. You repeat the sequence continuously by placing one-third of the starting amount on the first bet. If you lose the first bet, you place the remaining two-thirds on the second bet.

## The Labouchère strategy

The Labouchère system is a gambling strategy for even money games where you decide how much you want to win and write down a sequence of numbers. Whenever you win, you remove the left-most and the right-most numbers. When you lose, you add a number equivalent to the amount lost to the right of the number sequence.

## The reverse Labouchère strategy

The reverse Labouchère plays the exact opposite of the original Labouchère system. The difference is that when you win, you add the winning number to the right-most end of your sequence, and when you lose, you remove the left-most and right-most numbers.

## The four pillars strategy

The four pillars strategy is a high coverage system where you bet six units and cover 24 numbers. The name comes from a player who built this system, where the 14, 15, 17, and 18 corner bet is the centerpiece of it. Playing the four pillars, you can lose a maximum of 6 units per round or win a maximum of 12 units per round.

## The Hollandish strategy

The Hollandish strategy is a negative progressive roulette system where you wager on even-money bets. It's similar to the Martingale strategy, where your stake increases if you lose and reset when you win. The critical difference is that you make bets in rounds of three (instead of one), and your base unit bets increase by two units for each losing round.
