Definition of Soccer Accumulator Bonus

What does the term "soccer accumulator bonus" mean? What is meant by a "soccer accumulator bonus" in the world of sports betting?

Some sportsbooks, in an effort to attract new business or say thanks to their most loyal customers, will offer something called a Soccer Accumulator Bonus.

This bonus applies to soccer accumulators that:

1) Involve certain leagues (usually English Premier League and other major leagues)
2) Involve certain types of bets (Full Time Result, Both Teams to Score)

The more selections you have in your accumulator, the bigger your potential bonus.

Here is how one major sportsbook structures their bonus:

Treble - 5% bonus
4-Fold - 10% bonus
5-Fold - 12% bonus
6-Fold - 15% bonus
7-Fold - 20% bonus
8-Fold - 25% bonus
9-Fold - 30% bonus
10-Fold - 35% bonus
11-Fold - 40% bonus
12-Fold - 50% bonus
13-Fold - 60% bonus
14-Fold and Up - 70%

So, if you were eligible for a soccer accumulator bonus and hit your 4-fold for a total profit of £100, you would receive an extra bonus on top of that of £10.
