Definition

Parimutuel betting differs from fixed-odds betting in that the final payout is not determined until the pool is closed – in fixed odds betting, the payout is agreed at the time the bet is sold.

Parimutuel gambling is frequently state-regulated, and offered in many places where gambling is otherwise illegal. Parimutuel gambling is often also offered at "off track
Off-track betting
Off-track betting refers to sanctioned gambling on horse racing outside a race track.-US history:...

" facilities, where players may bet on the events without actually being present to observe them in person.

Example

Consider a hypothetical event which has 8 possible outcomes, in a country using a decimal currency such as dollar
Dollar
The dollar is the name of the official currency of many countries, including Australia, Belize, Canada, Ecuador, El Salvador, Hong Kong, New Zealand, Singapore, Taiwan, and the United States.-Etymology:...

s. Each outcome has a certain amount of money wagered:
1 $30.00
2 $70.00
3 $12.00
4 $55.00
5 $110.00
6 $47.00
7 $150.00
8 $40.00


Thus the total pool of money on the event is $514.00. Following the start of the event, no more wagers are accepted. The event is decided and the winning outcome is determined to be Outcome 4 with $55.00 wagered. The payout is now calculated. First the commission or take for the wagering company is deducted from the pool, for example with a commission rate of 14.25% the calculation is: $514 × (1 - 0.1425) = $440.76. The remaining amount in the pool is now distributed to those who wagered on Outcome 4: $440.76 / $55 ≈ $8 per $1 wagered. This payout includes the $1 wagered plus an additional $7 profit. Thus, the odds on Outcome 4 are 7-to-1 (or, expressed as decimal odds
Fixed-odds gambling

, 8).

Often at certain times prior to the event, betting agencies will provide approximates for what should be paid out for a given outcome should no more bets be accepted at the current time. Using the wagers and commission rate above (14.25%), an approximates table in decimal odds would be:
1 $14.69
2 $6.30
3 $36.73
4 $8.01
5 $4.01
6 $9.38
7 $2.94
8 $11.02

, the pool size often extends into millions of dollars with many different types of outcomes (winning horses) and complex commission calculations.

, 10¢ intervals are used. The rounding loss is sometimes known as breakage and is retained by the betting agency as part of the commission.

The above description of the mechanics of parimutuel wagering would suggest that it is impossible for the wagering company (the "house") to lose money, as the commission is deducted before the payouts are calculated. However, in rare circumstances, it is possible for the house to lose money on an event. This situation can occur when there are legal requirements for minimum winning payouts (for example, there may be a legal requirement to pay at least $1.10 on a winning one dollar wager). If the minimum legal winning payout exceeds the payout computed by the standard parimutuel mathematics by a sufficient amount, the house might lose money on this set of wagers.

In horse racing, a practical example of this circumstance might be when an overwhelming favorite wins. The parimutuel calculation results might call for a very small winning payout (say, $1.02 or $1.03 on a dollar bet), but the legal regulation would require a larger payout (e.g., $1.10 on a dollar bet). In North America, this condition is usually referred to as a minus pool.

Algebraic summary

In an event with a set of n possible outcomes, with wagers W1, W2, …, Wn the total pool of money on the event is


After the wagering company deducts a commission rate of r from the pool, the amount remaining to be distributed between the successful bettors is WR = WT(1 − r). Those who bet on the successful outcome m will receive a payout of WR / Wm for every dollar they bet on it.

, the most common types of bet on horse races include:
  • Win – to succeed the bettor

  • Place – the bettor must pick a horse that finishes either first or second
  • Show – the bettor must pick a horse that finishes first, second or third
  • Exacta, perfecta, or exactor – the bettor must pick the two horses that finish first and second, in the exact order
  • Trifecta
    Trifecta
    In horse racing terminology, a trifecta is a parimutuel bet in which the bettor must predict which horses will finish first, second, and third in exact order. The word comes from the related betting term, "perfecta". A trifecta is known as a tiercé in France and Hong Kong and as a tris in Italy.It...

    In mathematics, the notion of permutation is used with several slightly different meanings, all related to the act of permuting objects or values. Informally, a permutation of a set of objects is an arrangement of those objects into a particular order...

    s of the numbers in the box. An exacta box with 2 numbers, commonly called quinella or quiniela, is a bet on either of two permutations: A first and B second, or B first and A second. A trifecta box with 3 numbers has 6 possible permutations (of the horses in the 'box' 3 can finish first, 2 can finish second, and one can finish third, 3 × 2 × 1) and costs 6 times the betting base amount. A trifecta box with 5 numbers has 60 possible permutations and costs 60 times the betting base amount (5 × 4 × 3). In France, a 'box' gives only the ordered permutations going along an ordered list of numbers such that a trifecta box with 6 numbers would cost 20 times the base amount
  • Any2 or Duet – The bettor must pick the 2 horses who will place first, second or third but can finish in any order. This could be thought of as a double horse show key (see below)
  • Double – the bettor must pick the winners of two successive races (a 'running' or 'rolling' double); most race tracks in Canada and the United States take double wagers on the first two races on the program (the daily double) and on the last two (the late double)
  • Triple – the bettor must pick the winners of three successive races; like doubles, many tracks offer 'running' or 'rolling' triples. Also called pick three or more commonly, a treble
  • Quadrella or Quaddie – The bettor must pick the winners of four nominated races at the same track
  • Sweep – the bettor must pick the winners of four or more successive races. In the US, this is usually called pick four and pick six, with the latter paying out a consolation return to bettors correctly selecting five winners out of six races, and with "rollover" jackpots accumulating each day until one or more bettors correctly picks all six winners


Win, place and show wagers class as straight bets, and the remaining wagers as exotic bets. Bettors usually make multiple wagers on exotic bets. A box consists of a multiple wager in which bettors bet all possible combinations of a group of horses in the same race. A key involves making a multiple wager with a single horse in one race bet in one position with all possible combinations of other selected horses in a single race. A wheel consists of betting all horses in one race of a bet involving two or more races. For example a 1-all daily double wheel bets the 1-horse in the first race with every horse in the second.

People making straight bets commonly employ the strategy of an 'each way' bet. Here the bettor picks a horse and bets it will win, and makes an additional bet that it will show, so that theoretically if the horse runs third it will at least pay back the two bets. The Canadian and American equivalent is the bet across (short for across the board): the bettor bets equal sums on the horse to win, place, and show.

In Canada and the United States bettors make exotic wagers on horses running at the same track on the same program. In the United Kingdom

 bookmakers offer exotic wagers on horses at different tracks. Probably the Yankee occurs most commonly: in this the bettor tries to pick the winner of four races. This bet also includes subsidiary wagers on smaller combinations of the chosen horses; for example, if only two of the four horses win, the bettor still collects for their double. A Trixie requires trying to pick three winners, and a Canadian or Super Yankee trying to pick five; these also include subsidiary bets. The term nap identifies the best bet of the day.

A parlay or accumulator
Parlay (gambling)

  • Quadrella or Quaddie – The bettor must pick the winners of four nominated races at the same track
  • Big 6 – The bettor must pick the winners of six nominated races, which can be at the same track or split over two or more tracks


In Australia, certain exotic bet types can be laid as "flexi" bets. Usually the price of an exotic bet is determined by a set multiple of the outcome, for example $60 for a five horse boxed trifecta at one unit ($1) - or $30 at half unit (50c). If the bet is successful, the bettor will get either the full winning amount shown on the board, or half the winning amount. Under a flexi system the bettor can nominate their desired total wager, and their percentage of payout is determined by this wager's relationship to the full unit price. Using a five horse box trifecta, the bettor may wish to lay only $20 on the outcome. Their percentage of winnings is now calculated as $20/$60 = 33.3%. If the bet is successful, the payout will be 33.3% of the winning amount for a full unit bet.

In recent times the 'Roving Banker' variant for Trifecta and First4 betting is now offered. For a Roving Banker First4 select one, two or three runners that you believe will definitely finish 1st, 2nd, 3rd or 4th. Choose up to 3 selections as Roving Banker(s) with other runners to fill the remaining place(s). A Roving Banker Trifecta is where you believe that one or two runners will definitely finish 1st, 2nd or 3rd. You can place your bet by picking your favourite runner to finish in any place within your bet and complete the Trifecta with any number of other runners to fill the other placing(s).
