For example, you have selected five wagers, you may choose to bet on the system 4/5 . This means that you will receive your winnings if at least four of your five wagers are correct. The same principle applies if you choose a system 3/5 ; you will receive your winnings if at least three of your wagers are correct.
What is a system 2/3 (3 bets)? A 2/3 system consists of 3 bets which transpire from 3 picks -- three 2-pick multis (parlays). At least two of the three picks must be correct to gain some winnings - the exact amount of the winnings depends on how many of the predictions prove correct.
