Full-cover bets are the oldest system bets in the book: pick three or four selections and bet every combination of them at once. Irish punters have been writing Lucky 15s on race days for generations. This guide gives the honest arithmetic — how many bets you’re really placing, what it costs, and when full cover genuinely beats a straight acca.
The family tree
Every full-cover bet is defined by two things: the number of selections, and whether singles are included. Without singles: a Trixie on 3 selections is 4 bets (3 doubles + 1 treble); a Yankee on 4 is 11 bets (6 doubles + 4 trebles + 1 four-fold); a Canadian on 5 is 26; a Heinz on 6 is 57; a Super Heinz on 7 is 120; a Goliath on 8 is 247. Add the singles and the names change: a Patent is a Trixie plus 3 singles (7 bets), a Lucky 15 is a Yankee plus 4 singles, a Lucky 31 a Canadian plus 5, a Lucky 63 a Heinz plus 6.
Cost: the stake multiplies, quietly
The quoted stake is per line. A “€1 Lucky 15” costs €15; a €2 Goliath costs €494. Each-way doubles it again: a €1 each-way Lucky 15 is 30 bets and €30 off your balance. This is the first honest check before placing one — divide what you’re happy to risk by the number of lines, and that’s your unit stake, not the other way round. Our Lucky 15 calculator does the returns arithmetic for any result pattern.
What one winner actually pays
The “Lucky” families exist because the singles mean one winner still returns something. The maths deserves daylight: in a €1 Lucky 15 (€15 staked), one winner at 4/1 returns the €5 from its single — a €10 overall loss. The marketing framing is “you still collect with one winner”; the arithmetic framing is “you collect a third of your outlay”. With a Trixie or Yankee, one winner returns nothing at all, because every line needs at least two selections to land.
The bonuses bookmakers attach
Because these bets stake many lines at multiplied margins, bookmakers like them — and many sweeten them with concessions such as enhanced odds on a sole winner in a Lucky 15, or a percentage bonus when all selections win. The exact offers vary by bookmaker and change often, so treat them as advertised promotions to verify in the terms on the day, not as fixed rules. The sweeteners are real value when they apply, but they exist because the underlying product carries the margin of every combination inside it.
Full cover vs the straight acca
A €15 four-fold acca beats a €1 Lucky 15 when all four win — the acca concentrates the whole stake on the best-paying line. The Lucky 15 wins the comparison when results are mixed: two or three winners pay the doubles and trebles while the acca pays nothing. So the choice is really a probability statement: full cover is insurance against near-misses, and like all insurance you pay for it — here, by spreading stake onto lower-odds lines. If your selections are short-priced favourites, the doubles pay pennies and the insurance is poor value; full cover suits genuine prices (around 2/1 and up) where a double is worth collecting.
Honest conclusions
Know the line count before you write the slip, set the unit stake from total outlay, expect one winner in a Lucky 15 to mean a loss, and read the day’s bonus terms rather than assuming them. Full-cover bets are a legitimate, sociable way to bet a race day — just price the insurance honestly. 18+ — Gambling Awareness Trust, 1800 753 753, gamblingcare.ie.
Frequently Asked Questions
A Trixie is 4 bets on 3 selections; a Patent adds the singles to make 7; a Yankee is 11 bets on 4 selections; a Lucky 15 adds the singles to make 15. The quoted stake is per line, so a €1 Lucky 15 costs €15.
Yes — the winner’s single pays. But it rarely covers the outlay: one 4/1 winner in a €1 Lucky 15 returns €5 of the €15 staked — a €10 loss overall.
They answer different questions: the same total stake on a four-fold acca pays far more if all four win, while the Lucky 15 pays something on mixed results where the acca pays nothing. Full cover is insurance against near-misses — best value on selections at real prices rather than short favourites.
