A treble bet is a single wager based on three different selections, all of which must win in order for the bet to be successful.
It is a form of accumulator bet, in which the winnings from one successful selection are placed on the second and then the combined winnings of selections 1 and 2 are placed on the third selection.
If any one or more of the selections loses, then the bet is a loser.
This is the simplest definition of what the treble is. However, there is more to understanding it than backing three selections and hoping they all win.
So, we need to answer a couple of key questions:
Let’s now answer these questions and go into more detail about what a treble bet is, by giving you a clear example of one, exploring which sports are good options for trebles and how easy or difficult it is to place these bets with most online bookmakers, such as bet365 Sport.
In answer to the query of what a treble bet is, we explained that it is a three-selection wager on which the winnings of each selection are placed onto the next, provided each selection is a winner.
At the end of the outcome of all three selections, if all three have won, then you have won the wager and will earn a return.
However, you don’t have to wait until the bet is complete because you can see the effective odds for your treble using a simple calculation.
Firstly, we recommend using decimal odds for this calculation as it makes things much easier.
Let’s say that a punter places a £10 treble bet on three selections:
Using the decimal odds, the calculation to work out the effective odds of this bet is simple. You just multiply the decimal odds together:
5.00 x 2.00 x 4.00 = 40.00 (= 39/1)
So for a £10 stake, you multiply the decimal odds by the stake to get your total potential return.
40.00 x £10.00 = £400.00
£390 of which is profit and £10 of which is your stake money returned.
You use this same calculation using decimal odds for any Treble Bet selection. Simply substitute in the decimal odds for each selection A, B and C into the formula:
A x B x C = Total Decimal Odds.
Then it is Total Decimal Odds x Unit Stake to see your total potential return.

In betting, the term ‘trebles’ or ‘treble’ usually refers to a the treble bet outlined above. The Treble bet is one of the most common and popular forms of accumulator bet, so it is a term in common usage across betting sites and within the industry.
The only times the term Trebles may not apply to a three-selection, single-line bet is in the context of darts betting, where there may be a market on how many trebles will be scored in a match. That’s because on a dartboard, there are single, double and treble segments for each of the 20 numbers around the board.
It can also be applied to football bets where you are placing a bet on one team winning three major trophies, such as the Premier League, FA Cup and Champions League. While winning three trophies is called a ‘treble’ if you bet on this outcome, it is still a three-selection bet of a single line. It is just a wager on one team winning all three tournaments named as part of the bet.
Here’s a good example of a £5 Treble Bet taken from horse racing markets available on the 26th of February 2025 at bet365 Sport.
Let’s now transfer those decimal odds into the A x B x C calculation:
5.00 x 7.00 x 5.00 = 175.00 (174/1)
Then to work out our potential return from the bet, you multiply the total decimal odds by the £5 stake.
175.00 x £5.00 = £875.00
You can see here that even a relatively small initial wager of £5, with three middle value odds selections, can still generate a massive potential return.
Many punters will back treble bets rather than three single bets as it is a lower initial bet cost per unit stake, and offers a significantly higher return.
For example, if you backed the three selections above with one single £5 bet on each. Then your maximum win would be £120, £15 of which would be your stake money returned.
With the treble, not only do you risk just £5, as opposed to £15, but your total potential return is £755 MORE than what you would get if all three singles were winners.
However, the one benefit of backing the options singly as opposed to a treble, is that if just one or two selections win, then you generate a return (and profit), whereas if one or two selections win with a treble, the bet is a loser.
The good news is that it is easy to place treble bets on a massive range of different sports. In fact it is hard to think of a sport where it may not be possible to formulate a treble bet!
Certainly, they are a popular option on horse racing, greyhounds, tennis, football, basketball, American football, darts, snooker and many other sports besides.
Trebles can be comprised of selections from one sport, such as putting three football full time results into a treble bet, or a mix of sports (picking a horse to win a race, a football team to win a match and a darts player to win their match, for example).
Furthermore, features on sites such as bet365’s Bet Builder+, allows customers to make even more choices to add to their bet slip from a wider range of sports and markets than ever before.
Yes, it is very easy to place a treble bet with a bookmaker. Simply follow the process below:
That’s all you need to do to place a treble bet!
A. A treble bet is a single wager of three selections, all of which must win in order for the bet to be a winner.
A. An each-way Treble is a bet which covers all three selections in the treble bet as both a winner of the event, but also covers a place finish too. Not all treble bets can be made into each way bets (for example, a treble bet on the outcome of three football matches cannot be made into an each way treble, but a treble bet on three horses to win their respective race can). With an each way treble you place one bet on the three horses to win and another on the three horses to win or place. This means an each way treble costs two-times the standard bet amount.
A. No. Treble bets, even those comprising of those with selections of lower value odds, are not easy to win. The higher the odds on each selection, then the more difficult it is likely to be for the bet to win. However, the upshot is that the return on a successful treble bet will be greater.
A. A treble bet has three selections. A double bet has two and four-fold accumulator has four. In all cases, the bet type (an accumulator) is the same. It is merely the number of selections that differentiates the different types of bet.
A. No. A Treble Bet is a single line, single stake accumulator bet of three selections. A Trixie bet also includes backing each of the three selections as a series of three double bets (A&B, A&C and B&C) as well as a standard Treble (A, B & C to win). A Trixie bet is a type of wager called a full cover bet and requires 4x your unit stake to place.
