Log into Ladbrokes with your account, and open the sports betting section. If the feature is available, check out the markets you can use. Select Accumulator as bet type, and add the markets you want from the list of valid options. Set the stake and place your accumulator bet. The Accumulator feature, while only available for certain events and specific situations, is a very popular feature. Placing an accumulator bet is just as simple as placing a regular sports bet. The only difference is that you need to select Accumulator, and meet the requirements of the bet type.
