Quinella

A quinella is a bet on the first two finishers of a race, taken in either order. One combination covers both sequences, and that single feature is what separates it from an exacta.

The definition holds across racing codes and jurisdictions. Almost everything attached to it does not. Commission, scratched runners, dead-heat division and the fate of an unbacked pool sit in operator rulebooks rather than in the bet type, so two quinellas settled under different rules can pay differently on identical results.

What a quinella is

A quinella qualifies for a dividend when the two selected runners fill the first two placings, whichever of them crosses the line first. TAB states the rule without qualification: selecting the first two runners past the post in any order, with no requirement to nominate which finishes where. The Hong Kong Jockey Club defines its Quinella pool on the same basis — first and second in either order.

The wager is a totalisator product at most operators rather than a fixed-odds one. Stakes enter a pool dedicated to that bet type in that race, and no price is locked in at placement — any figure displayed beforehand moves while betting remains open. TAB runs quinella pools across thoroughbred, harness and greyhound racing.

A worked example

In a race with eight declared starters, a backer takes runners 3 and 7 in a straight quinella for one unit.

The bet qualifies on two results: 3 first and 7 second, or 7 first and 3 second. Every other finish returns nothing, including 3 first and 7 third.

How the dividend is calculated

The pool determines the payout in two steps: the operator deducts its commission from the gross pool to leave the net pool, then divides the net pool by the number of winning unit bets.

Published rates make the arithmetic concrete. TABtouch applies a commission of 17.50% to quinella pools combined with SuperTAB or run on a Western Australian standalone basis, and the host’s rate when a pool is commingled internationally [3]. On a gross pool of $100 000 at that rate, the net pool is $82 500; against 5 000 winning $1 unit bets, the dividend is $16.50 per $1.

Rounding is also a rulebook matter: HKJC declares quinella dividends in multiples of 50 cents and pays none below the unit bet plus 50 cents. Rates differ by operator, pool and jurisdiction, so no single figure describes the bet type.

Quinella against exacta

An exacta requires the correct order, and TAB lists the two as separate bet types. HKJC runs the ordered equivalent as its Forecast pool.

The structural difference is combination count. Two runners produce one quinella combination and two exacta combinations, so covering both orders through exactas takes twice the outlay of the equivalent quinella at the same unit stake.

Dividends are not comparable in advance. Each bet type funds its own pool, so quinella and exacta dividends on the same finishing order come from separate distributions of stakes, and neither can be derived from the other.

Straight, boxed and banker quinellas

Three staking structures appear in operator rulebooks, and the labels vary more than the mechanics.

A straight quinella carries two selections and one combination. TAB’s Victorian retail betting card requires a minimum of two selections.

A boxed quinella carries three or more selections and covers every pairing among them. Harness Racing New Zealand sets out the cost at a $1 unit: three runners boxed cost $3, four cost $6 and five cost $10

A banker quinella nominates one runner to finish first or second and pairs it with a group of others. The same structure appears as anchor or standout depending on the rulebook, and TAB lists Standout among the options available on a quinella.

Flexi staking sits across all three. The backer sets a total outlay and receives that proportion of the declared dividend, with TABtouch requiring the resulting percentage to exceed 1% for the bet to stand.

How many combinations a selection covers

The combination count for n selections is n(n − 1) / 2, because a quinella pairing is unordered.

Three selections give 3 combinations, four give 6, five give 10 and eight give 28, matching the Harness Racing New Zealand costs above. Outlay is the combination count multiplied by the unit stake unless flexi staking applies.

Scratchings, dead heats and refunds

This is where rulebooks separate, and the differences are not cosmetic.

On scratchings, HKJC refunds bets involving a withdrawn runner, while TABtouch refunds every eliminated combination, and in full if the race is abandoned or postponed [3]. HKJC also closes the quinella pool and refunds all bets if withdrawals leave fewer than three starters.

Dead heats split the dividend by combination. TABtouch states that a two-way dead heat for first leaves the dividend on those two selections unaffected, while a dead heat for second produces two winning combinations, each paying 50% of the full dividend HKJC divides the net pool into as many parts as there are backed winning combinations. Canada’s Pari-Mutuel Betting Supervision Regulations define a winning quinella, where two or more horses dead-heat for first, as any two of those horses in either order.

Unbacked winning combinations are handled in opposite directions. HKJC pays the first and third horses, then the second and third if that is also unbacked, then refunds all bets. TABtouch carries the net quinella pool forward to a later race. HKJC applies a further rule to insufficient finishers, paying all bets including the single finisher when one horse completes and refunding everything when none do.

FAQ

Bottom line

The definition of a quinella is one sentence and travels everywhere: the first two finishers, either order. What a winning ticket is worth does not — commission, rounding, carryover, dead-heat division and refund thresholds are set in each operator’s rulebook, and that document settles the number rather than the bet type.
