The so-called Paroli strategy is one of the most popular strategies in roulette. Basically, it is the opposite of the also very well-known Martingale strategy. If you follow the Paroli strategy, you increase your Bet after you have made a win in the previous game. Originally, the "Paroli" meant a card in the so-called Pharaoh's game, which is marked by the respective owner, after he has won, by bending one corner upwards. With this upward bending is meant that the actual win is used again together with a new bet.
If you, as a Player in Roulette, want to bet your won chips a second time on the original chance, you can announce this to the Croupier with the word "paroli". The Paroli strategy is basically considered to be capital-saving, since the player starts again with a small bet amount in the event of a loss and does not double the stakes - as is the case with the Martingale strategy. Experienced players often set a goal in advance when using the Paroli strategy, for example, triple Paroli. Since the Paroli strategy is straightforward and thus easy to understand, it is also popular among roulette beginners.
Basically, gambling fans can apply the Paroli strategy to other types of gambling as well. So, theoretically, players can also play Paroli on Slot machines or blackjack. By the way, there is also a saying"to parry someone".
