Bettors prefer DNB accumulator bets to the classic 1X2 bet type because they’re safer. Suppose you place a 4-fold ACCA with one draw and no bet included; if your pick is voided, the accumulator doesn’t fail. Your bet becomes a treble, and the other parts remain active. The total payout is affected because the odds of the voided pick are deducted from the ACCA odds.
