What is a Lucky 63 system?

A Lucky 63 system consists of 63 bets which transpire from 6 picks. One single bet per pick, fifteen 2-pick multis (parlays), twenty 3-pick multis (parlays), fifteen 4-pick multis (parlays), six 5-pick multis (parlays) and one 6-pick multi (parlay). At least one of the six picks must be correct to gain some winnings - the exact amount of the winnings depends on how many of the predictions prove correct.
