Trifecta Bet Explained: How the Tote Trifecta and Exacta Work

A trifecta asks one question about a race: which three horses finish first, second and third, and in what order? Get it exactly right and you share the trifecta pool with every other ticket that did the same. Get two of the three right, or all three in the wrong order, and a straight trifecta loses.

It is a tote bet, so there is no price when you place it. That makes it a different kind of bet from almost anything a bookmaker sells, and it is worth understanding how the pool works before looking at the ways of covering more than one order.

How does a trifecta work?

Every trifecta stake on a race goes into one pool. After the race, a deduction is taken from the pool and the rest is divided between the winning tickets, in proportion to what each staked on the winning line. The result is published as a dividend to a £1 stake.

So the size of the return has nothing to do with odds agreed in advance. It depends on two things: how much went into the pool, and how many people named the same three horses in the same order. A popular order, such as the first three in the betting finishing as expected, is usually shared by many tickets. An order that includes an outsider in the frame may be held by very few, which is when a trifecta pays a large sum for a small stake.

The practical difference from fixed odds is that you can’t know in advance what a winning trifecta will be worth. You can only judge whether the order you like is one many other people are likely to have.

Straight, combination and banker trifectas

A straight trifecta is one line: horse A first, B second, C third. It is the cheapest version and the hardest to win, because the three horses have to finish in exactly that order.

A combination trifecta covers every order of the horses you choose. Three horses can finish in six orders, so a combination on three is six lines. Four horses make 24 lines, and five horses make 60. The count is the number of horses multiplied by one fewer, multiplied by two fewer.

A banker trifecta is a middle way. You name one horse you are confident will win, and cover the others in every order for second and third. With the banker and three others, that is 3 × 2 = 6 lines. With the banker and four others, it is 4 × 3 = 12 lines. It costs far less than a full combination on five horses, and it asks you to be right about only one position for sure.

The same banker idea works in other positions. Some bettors fix a horse to finish second or third rather than first, or fix two horses and leave the third place open. What matters is the count of lines, because every line costs a stake.

Costing a trifecta

Multiply the number of lines by the line stake and you have the cost of the ticket. A 50p combination trifecta on four horses is 24 lines at 50p, which is £12. A 50p banker trifecta with four others is 12 lines, £6. A 20p combination on five horses is 60 lines at 20p, £12 again.

Those three tickets cost roughly the same and cover very different ground. The five-horse combination is the widest net: any three of your five in any order. The four-horse combination needs three of four. The banker needs your banker to win and two of the four others to follow it home. Which one is right depends on how strongly you rate a single horse.

Minimum stakes for tote bets are set by the tote and differ between betting on course, in a shop and online, so check the rules where you are betting. The dividend is always to £1, so a line staked at 50p receives half the declared dividend.

A trifecta settled, with an invented dividend

Suppose three of your four horses fill the first three places, and the race declares a trifecta dividend of £212.60 to a £1 stake. That figure is invented for the example.

The 50p combination on four horses has exactly one winning line, the order that happened. It returns half of £212.60, which is £106.30, from a £12 stake. The 50p straight trifecta, had you named that exact order, would also have returned £106.30, from 50p. The difference between those two stakes is what you pay for not having to know the order.

It helps to think of the combination as a price you set yourself. Here, the combination on four horses cost 24 times the straight ticket. It pays back only if the dividend is more than 24 times the line stake, and in this example it was: £106.30 against £12. On a race where the first three are the three shortest in the betting, a dividend of under £24 to £1 is entirely possible, and the same four-horse combination would then return less than it cost, even though it won.

If your banker had won and two of your others had finished second and third, the banker ticket would also have held one winning line and returned £106.30, from £6. That is the case for a banker when you really do trust one horse: half the cost of the full combination for the same return.

The exacta: the first two in order

The exacta is the trifecta’s shorter version. You pick the first two in the correct order, and share the exacta pool if you are right. A straight exacta is one line. A reverse exacta covers both orders of two horses, two lines. A combination exacta on three horses covers every pairing in every order, six lines, and on four horses it is 12.

It is the tote’s version of the straight forecast, and the difference is the same as for the trifecta and the tricast. The bookmaker’s forecast is settled on the computer straight forecast, a dividend calculated from the starting prices. The exacta pays a share of its own pool, so its dividend depends on what everyone else backed. On a given race, the two can come out quite differently.

Which is better? There is no general answer, because it depends on the race and on what the public backs. A pair of well-backed horses is often found by many exacta tickets, which pulls the dividend down. A less obvious pair, backed by few, can pay more in the pool than the calculated forecast.

Non-runners, favourites and the rules

The tote’s rules for trifectas and exactas are strict about naming. Every horse has to be named on the ticket, and there is no unnamed favourite option like the one that catches a Placepot non-runner.

If a horse on your ticket doesn’t run, the lines that include it are void and their stakes are returned. On a straight trifecta, that is the whole bet. On a combination or banker ticket, the lines that don’t involve the non-runner carry on as normal. A four-horse combination that loses one horse becomes, in effect, a three-horse combination, with the other stakes refunded.

Small fields change the pools too. The tote sets a minimum number of runners for these bets and can void the pool, or pay only part of it, if a race falls below the level set in its rules. That is worth checking on a day of heavy ground and a lot of withdrawals.

Where the trifecta fits

A trifecta is a bet for races where you have a real view on more than the winner. That usually means a big-field handicap, where the form points to a small group of horses and the rest look out of their depth. In a small field with a strong favourite, the likely orders are so obvious that the pool is shared many ways.

It also rewards being selective. Every extra horse in a combination multiplies the lines, and a ticket that covers most of the field has bought itself a near-certain small loss: the one winning line rarely pays for all the ones that lose. The tickets that pay well tend to be small, with a clear opinion about the race.

A useful way to build a ticket is to start from the positions rather than the horses. Ask which horse you are most confident will win, which two or three can finish second, and which wider group can fill third. Say the banker is A, the horses for second are B, C and D, and the horses for third are B, C, D, E and F. That is an unusual combination, but it is a clear opinion, and its lines can be counted: three choices for second, and for each of them four choices left for third, so 3 × 4 = 12 lines. Writing the count down before you place the ticket is the easiest way to avoid a bet that costs far more than you meant.

For the bookmaker’s version of these bets and how the CSF and CT are calculated, see forecasts and tricasts. For how the tote pools work across a whole meeting, including the Jackpot and the Scoop6, see tote betting. And if you want the whole card rather than one race, the Placepot spreads the same pool idea across six races, asking only for a placed horse in each.

One last detail that trips up new tote players: the published trifecta dividend and your return are not the same number unless you staked £1 a line. Scale the dividend to your line stake first. A 10p line on a £212.60 dividend is £21.26, not £212.60.
