Winning Bet Leads to Doubling the Next Stake / Losing Bet Retains the Same Stake


Assume you have £100 to bet on a live Premier League game between Arsenal and Manchester United. Your first wager could be on which team scores first. If you place a £2 bet on Arsenal and they score first, your next bet will be doubled to £4. (However, if Manchester United scores first, your subsequent wager remains at £2.) If your next bet is that “both teams will score” by halftime and it happens, the third bet will be raised to £8.

Paroli Betting System Variants

As experts continue to analyze the Paroli system, they’ve developed variations that offer unique approaches to the original method. Two such versions are the Extended Paroli and the Inverted Paroli, which are described below.

Extended Paroli

This version highlights the advantages of the system, focusing on maximizing profits while minimizing losses. The staking strategy hinges on your total betting budget. With each win, the stake is doubled, while a loss prompts the bettor to maintain the same stake. After securing three consecutive victories, the bettor should cease betting, as the chances of winning again diminish.

Inverted Paroli

The Inverted Paroli resembles the Martingale betting system in the structure. It concentrates more on managing losses rather than maximizing wins; if you lose a stake, you double the next one to recoup the initial loss. A win implies a profit, therefore, there’s no necessity to boost the stake size.
