Selections
A quick tour of the exotics
There is a distinction worth keeping straight from the off. A Trixie, Yankee, Canadian, Heinz, Super Heinz and Goliath all contain only the multiple bets — doubles, trebles and upwards — but no singles. A Patent, Lucky 15, Lucky 31 and Lucky 63 are the same bet plus singles on every selection, which is why they cost you one, four, five or six extra unit stakes respectively. The trade is that you need only one winner to get something back.
In descending order of size: Goliath (8 selections, 247 bets) and Super Heinz (7, 120) are the big-field specials, typically run on Saturday accumulator cards. A Heinz is 57 bets across 6 selections. Lucky 63 is the same six selections but with singles included. Below that, the Canadian (also called Super Yankee) and Lucky 31 cover five selections. A Yankee covers four, a Lucky 15 the same four with singles. Trixie and Patent cover three. Everything smaller is a named double or treble.
Most British bookmakers pay bonuses on Lucky bets: commonly a treble the odds for a single winner in a Lucky 15, and a 10% or 25% bonus on all-winner bets. These vary by firm and are not included in the figures above — check the shop rules before claiming. Each-way multiples stake is doubled (one bet to win, one to place) and the place returns are calculated at the place fraction of the odds for every placed leg, which is why a partial result can still return something meaningful even if the win side collapses.
A word of honest caution. Exotic multiples look romantic on the slip and pay out rarely. A Goliath with six winners and two losers from reasonably priced selections will often return less than the stake — the arithmetic simply does not stretch far enough to cover the bets that failed. Run as a regular strategy they tend to bleed. They are best treated as occasional flutters, or as a structured way of coupling a genuine punt with some downside protection.
Worked example
You have four selections: a 2/1 shot, a 5/2 shot, a 7/2 shot and a 4/1 shot. You place them in a £1 unit Lucky 15 — that is £15 total stake (four singles, six doubles, four trebles, one fourfold, being fifteen lines of £1 each). Say two horses win (the 2/1 and the 5/2). The two winning singles pay £3 and £3.50. The one winning double (2/1 × 5/2) pays £10.50 — from a £1 stake at combined decimal odds of 10.5. The trebles and the fourfold all lose because at least one leg in each is a loser. Total return £17, profit £2 on a £15 stake. Had all four won, the fourfold alone would have paid 3 × 3.5 × 4.5 × 5 = £236.25 on £1, and the full Lucky 15 would have returned more than £300.
Common mistakes
The most persistent confusion is about what the numbers in the bet names mean. A Lucky 15 is fifteen bets from four selections, not fifteen selections. A Heinz is fifty-seven bets from six selections, named after the 57 varieties. The Goliath is 247 bets from eight selections — hence the name. The second confusion is that each-way multiples double everything: a £1 each-way Lucky 15 costs £30, not £15, because every one of the fifteen lines is a pair of bets. The third is that "Patent" and "Lucky 15" sound similar but are not the same — a Patent is three selections and seven bets with singles; a Lucky 15 is four selections and fifteen bets with singles.
What to watch for
Non-runners in a multiple reduce it by one leg. The Lucky 15 versus Yankee piece explains when each is the better structure — short version: Lucky 15 wins when your four selections include longer prices and you want the single-winner bonuses most firms pay; Yankee wins when you genuinely fancy all four at shorter prices and want to concentrate the stake on the multiple legs. The Rule 4 calculator handles the case where one of your winning legs is affected by a late withdrawal — the deduction propagates through every multiple that leg is part of.
Frequently asked questions
What's the difference between a Lucky 15 and a Yankee?
Both are built on four selections. A Yankee is 11 bets — six doubles, four trebles and one fourfold. A Lucky 15 is 15 bets — the same 11 multiples plus four singles. The Lucky 15 pays out on any winner; a Yankee needs at least two winners for any return. The longer piece on Lucky 15 versus Yankee explains when each is the better structure.
How many bets is a Goliath?
A Goliath is 247 bets from eight selections — all possible multiples from doubles up to the eight-fold, with no singles. At a £1 unit stake, a Goliath costs £247. As an each-way Goliath it costs £494. It is the largest named multiple bet offered by most UK firms.
What happens with a non-runner in a multiple?
A non-runner reduces the multiple by one leg. The stake on all bets involving that leg is refunded, and the remaining bets settle at the original stake.
Do bonuses apply to my Lucky 15?
Most UK firms pay bonuses on Lucky 15, 31 and 63 bets — typically a single-winner bonus that doubles or triples the odds of one winning selection, or a four/five/six-winner bonus of a fixed percentage. Bonus structures vary by bookmaker and this calculator does not apply them by default; check your firm's rules and add the bonus manually to the displayed return if relevant.
