A fourfold bet combines four separate selections into a single wager, and all four selections must win for the bet to pay out in full. The odds of each selection are multiplied together to calculate the total payout, which can produce a sizeable return from a small stake.
How a fourfold works
A fourfold typically combines wagers of the same bet type from different events, such as four different match results, but punters can also mix market types. The overall price is the product of each selection's odds, and there is a natural trade-off: if just one of the four selections loses, the entire bet loses, with no partial return for three winning picks.
Bettors can reduce risk by adding trebles, doubles, and singles alongside the fourfold, but this increases the total stake significantly because of the number of bets involved. The all-or-nothing structure makes fourfolds higher risk than a single bet or a smaller accumulator like a double or treble, yet it also offers greater potential for a large payout from a relatively small stake.
Worked payout example
In an example using match results (1x2), four home teams are selected to win in four different games, all priced at 1/1, with a £10 stake. The returns from each leg roll into the stake for the next: £10 becomes £20, then £40, and finally £80 on the last selection if the first three win.
Thanks to compounding odds, a £10 wager would return £160, providing £150 in total profit after subtracting the original stake.
Fourfolds vs other accumulators
Doubles and trebles offer smaller returns but lower risk because they feature fewer selections. Accumulators can also extend beyond four legs, with fivefolds, sixfolds, sevenfolds, and eightfolds common among punters. Every added leg must win, and a fourfold is often seen as a middle ground: a realistic number of selections that could win on a single day while still offering a meaningfully bigger payout than a treble.
Some bookmakers run accumulator offers, including insurance, acca boosts, and acca clubs.
Responsible gambling and FAQs
Bettors are reminded to gamble responsibly, using safer gambling tools available on betting sites, setting a budget, taking regular breaks, and not chasing losses. Betting should be viewed only as entertainment, not as a reliable income. More information is available via GambleAware, GamCare, Gamblers Anonymous, and the NHS.
A fourfold bet wins when all four legs land; usually, even one losing leg means no returns. Bettors can include trebles, doubles, or singles to mitigate the risk. The four selections do not need to come from the same sport or event, as long as the outcomes are unrelated—for example, combining horse racing and football bets in the same fourfold.
