A progressive parlay is a joint wager on multiple events, for example team sports or horse races, however, unlike a regular parlay, if some of the individual bets lose, but most win, the bettor still wins, although with a much smaller payout, what is called, an accumulator, or combo bet is a single bet that links together two or more individual wagers and is dependent on all of those wagers winning together?
Progressive parlay A progressive parlay is a joint wager on multiple events, for example team sports or horse races. Generally a progressive parlay involves a joint wager on four to twelve separate events. Should all the selected bets win, the bettor receives a relatively large payout, because of the sizable odds against this happening. However, unlike a regular parlay, if some of the individual bets lose, but most win, the bettor still wins, although with a much smaller payout. Several sites use a schedule where the bettor can lose one bet on a 4-6 event progressive parlay, can lose up to two bets on a 7-9 event progressive parlay, and up to three bets on a 10-12 event progressive parlay.
Matching pennies Matching pennies is the name for a simple game used in game theory. It is played between two players, Even and Odd. Each player has a penny and must secretly turn the penny to heads or tails. The players then reveal their choices simultaneously. If the pennies match (both heads or both tails), then Even keeps both pennies, so wins one from Odd (+1 for Even, −1 for Odd). If the pennies do not match (one heads and one tails) Odd keeps both pennies, so receives one from Even (−1 for Even, +1 for Odd).
