A Block consists of 9 or more selections taking part in different events. The selections are combined to produce a Full Cover bet, comprising a straight Accumulator, and perms of all lesser Accumulators (4-Folds, 5-Folds, etc), down to Trebles and Doubles.
The Block Bet Calculator allows you to calculate the stake, return and profit for Blocks of up to 12 selections if required, with the same comprehensive range of options available to the Free Bet Calculator.
Note: Bet365 is the only online bookmaker that currently accepts a straight Block bet, although it can be emulated with other bookmakers by staking all of the component parts individually (i.e. Doubles, Trebles, 4-Folds, etc).
