Take for example US sports such as basketball and football where both point spread bets and total bets are 50/50 propositions offered at risk $11 to win $10. True odds does not mean “actual true odds” but it means the parlays pay the same amount regardless if a bettor used a parlay/accumulator or straight bets. I’ll cover these but first I’ll explain how parlays are calculated using true odds. There are exceptions, primarily with US friendly betting sites offering fixed odds that short the payout, and a couple sites that offer promotions that make the odds better. The vast majority of internet betting sites offer true odds parlays. In this article I’ll discuss parlay (accumulator) betting in great depth including their dynamics, warnings about short pays, who offers the best odds, and then conclude with parlay betting strategy. If all are correct a payout is issued for the accumulated odds. If at least one selection is incorrect the entire wager is a loss. In sports betting, a parlay (also known as an accumulator) is a wager that combines multiple individual wagers into a single bet and requires all those wagers are successful for the single bet to win.
