Accumulator free bets are free bets that you can only use on an acca. Typically, the bookmaker sets a minimum number of legs, often three or four. It also sets minimum odds for each leg or the whole bet. So you need to plan your selections before you place the free bet.
How accumulator free bets work
First, you claim the welcome offer by placing a qualifying bet. Then the bookmaker adds the free bets to your account, usually with an acca-only restriction. When you build your acca, each leg must meet the rules. Otherwise, the site won’t let you use the free bet. If the acca wins, you keep the winnings but not the free bet stake.
Common acca conditions
Minimum legs, minimum odds per leg and total odds limits appear most often. Some offers also exclude certain markets, such as bet builders or in-play bets. In addition, the free bets usually expire within seven days. Our guide to acca and bet builder free bets covers each rule in detail.
What accumulator free bets are really worth
The bookmaker’s margin builds up with every leg you add, so the expected return falls as the acca grows. For instance, a £10 free bet on a five-leg acca is usually worth noticeably less than £10 on average. That is why our estimated value score sits below the headline figure. We also score difficulty, which shows how hard the offer is to complete. In addition, our risk score shows how much of your own money you stake. See how we rate offers for more.
Tips for using acca free bets
Stick to the minimum number of legs, because each extra leg adds more margin. Also, choose markets you understand and check kick-off times so every leg settles before the free bet expires.
