Sporting Index: Boost Your Acca Offer Explained

Top online betting site Sporting Index has long been the biggest player in the spread betting gaming. Nothing has changed in that regard, but many don’t realise this widely respected company also offers an equally excellent traditional betting arm of the site. The Sporting Index sportsbook offers odds and markets on 25 sports and events, including the most popular betting pursuits of Horse Racing, Football, Golf, and the major US Sports.

Offering competitive odds across the board, Sporting Index also provides an array of attractive deals and promotions. New Fixed Odds Players can take advantage of a Bet £20 Get 2 x £10 Free Bets Sign-Up Deal, whilst existing customers benefit from great value offers across Horse Racing and Football.

Here, we look at the hugely popular Boost Your Acca offer, which grants additional winnings on successful football accumulator bets containing three or more selections. With the Premier League season reaching its climax and much to play for at both ends of the table, what better time to seek out a company which offers an additional reward for your winning wagers?

How Does the Boost Your Acca Offer Work?

Taking part in this promotion couldn’t be easier. Simply place a football accumulator containing three or more selections from the following markets:

Match Odds
Total Goals Over/Under
Correct Score
Double Chance
Half Time/Full Time
Half Time Result
Half Time Goals Over/Under
Both Teams to Score

If your bet wins, you will receive a percentage boost to your winnings. The more legs contained in your acca, the bigger the boots, as follows:

Legs	Bonus
3	5%
4	10%
5	15%
6	20%
7	25%
8	30%
9	35%
10	40%
11	45%
12	50%
13	55%
14	60%
15	65%
16	75%

All additional winnings are withdrawable as cash. As with all offers, certain terms and conditions are in place, with the following, in particular, worth being aware of.

The maximum winnings boost per bet is capped at £25,000
The maximum daily cumulative winnings boost across all bets is capped at £50,000
Accumulators containing boosted single selection do not qualify for this offer
Cash-Out Values are calculated using the original odds of the accumulator – not the boosted odds
If any legs are postponed or void, the Winnings Boost for the number of completed winning selections will apply
Bets placed using a Free Bet do not qualify for this offer
