Every Irish betting site on Tablet Betting accepts accumulator bets across football, horse racing, tennis, golf, cricket, and more. Use this guide to understand exactly how each type works before you place one, and pair it with our betting odds calculator to see what a given combination returns on any stake.

What Is an Accumulator Bet?

An accumulator is a single bet made up of four or more selections, where every selection must win for the bet to pay out. If one leg loses, the whole bet loses. The appeal is the odds: each selection’s price multiplies into the next, so a four-fold acca at average odds of 2/1 returns 81/1, while a five-fold at the same average returns 242/1. Small stakes can turn into four-figure returns, which is why accas feel like the lottery of sports betting.

Accumulators work on essentially any sport. Football is the most common, especially the Saturday 3pm kick-offs. Horse racing accas are also big, particularly on festival days like Cheltenham, Galway, Punchestown, and the Leopardstown Christmas festival. You can build accas across tennis, golf, cricket, rugby, darts, snooker, and any other sport your bookmaker covers. Some punters mix sports within one acca, combining a Premier League winner with a Formula 1 podium finish and a cricket match result.

How Accumulator Odds Are Calculated

The maths behind acca odds is multiplication, but you work in decimal odds rather than fractional. Convert each fractional price to decimal by calculating (X ÷ Y) + 1, multiply all the decimals together, then subtract 1 for the profit per €1 staked.

A quick worked example. Say you pick four teams at the following odds:

• Arsenal to win: 4/5 (decimal 1.80)
• Liverpool to win: 1/2 (decimal 1.50)
• Manchester City to win: 2/5 (decimal 1.40)
• Chelsea to win: Evens (decimal 2.00)

Multiply the decimals: 1.80 × 1.50 × 1.40 × 2.00 = 7.56. A €10 stake returns €75.60 in total, or €65.60 profit plus the original €10 stake. You can see why short-priced favourites accumulate quickly: four near-certainties at short odds still combine into a 6/1 shot.

The Tablet Betting odds calculator handles the conversion and multiplication for you, showing fractional, decimal, American, and implied probability for any single leg. For full acca calculations including Yankees and Lucky 15s, most bookmakers have a free bet calculator in their betting slip.

Types of Accumulator by Size

Accas are named by the number of selections:

• Double: 2 selections – technically a multiple, not an acca, but works the same way
• Treble: 3 selections – again technically a multiple
• Four-fold: 4 selections – the minimum “true” accumulator
• Five-fold: 5 selections
• Six-fold: 6 selections
• Seven-fold: 7 selections
• Eight-fold and beyond: 8+ selections, where most bookmakers apply their largest acca bonuses

Every extra leg multiplies the odds further but also multiplies the chance of the bet losing. A 10-fold acca of 2/1 shots returns roughly 59,000/1, but each leg has only a one-in-three chance of winning, so the probability of all 10 landing is under 0.002%. That is the trade-off accumulators live and die on.

Full Cover Bets: Lucky 15, Yankee, Heinz and More

A standard accumulator wins only if every leg wins. Full cover bets take the same set of selections but cover every possible combination of doubles, trebles, and accumulators within them. You can still get a return even if some legs lose, though you pay multiple stakes because each combination is a separate bet.

The main full cover bet types:

• Trixie (3 selections, 4 bets): 3 doubles + 1 treble. At least 2 winners needed for a return.
• Patent (3 selections, 7 bets): Trixie plus 3 singles. One winner pays out. Effectively a Trixie with insurance.
• Yankee (4 selections, 11 bets): 6 doubles + 4 trebles + 1 four-fold. Two winners minimum.
• Lucky 15 (4 selections, 15 bets): Yankee plus 4 singles. One winner pays out. Many bookmakers pay bonus returns if all four win or if only one wins.
• Canadian / Super Yankee (5 selections, 26 bets): 10 doubles + 10 trebles + 5 four-folds + 1 five-fold. Two winners minimum.
• Lucky 31 (5 selections, 31 bets): Canadian plus 5 singles. One winner pays out.
• Heinz (6 selections, 57 bets): 15 doubles + 20 trebles + 15 four-folds + 6 five-folds + 1 six-fold. Two winners minimum.
• Lucky 63 (6 selections, 63 bets): Heinz plus 6 singles.
• Super Heinz (7 selections, 120 bets): All doubles, trebles, four-folds, five-folds, six-folds, plus the seven-fold.
• Goliath (8 selections, 247 bets): Every multiple from doubles up to the eight-fold. No singles.

The stake multiplies with the number of bets. A €1 Yankee costs €11 (11 bets × €1). A €1 Heinz costs €57. A €1 Goliath costs €247. Each bet within the wager is priced separately, so a Lucky 15 where all four legs win often pays more than a straight four-fold acca at the same prices, because you also collect on the six doubles and four trebles.

Lucky 15, 31 and 63 Bonuses

Lucky bets are the full cover bets that include singles as well as the multiples. Most Irish bookmakers run two standard Lucky bet bonuses:

• One winner bonus: if only one of your Lucky selections wins, the odds on that single are doubled or tripled. This softens the blow when three of your four selections lose.
• All winners bonus: if every selection wins, bookmakers typically add 10-25% extra to your total returns.

The exact bonus terms vary by bookmaker and change over time. Check the specific terms before placing the bet, especially for Lucky 31 and Lucky 63 where the all-winners bonus can push the final payout well above what a standard calculation suggests.

Each-Way Accumulators

Each-way accumulators are particularly popular in horse racing. An each-way acca is essentially two accas stacked together: one for the win part (all selections must win) and one for the place part (all selections must finish within the advertised place terms, usually the top 2, 3, or 4 depending on field size).

The win part pays at full odds if every selection wins. The place part pays at a fraction of the odds (typically 1/4 or 1/5) if every selection places, including any that won. This means you can still collect something even if none of your horses actually win, provided they all place. Each-way accas are a favourite for festival meetings where fields are large and place terms are generous.

Stakes on each-way bets are doubled because you are effectively placing two bets. A €10 each-way four-fold costs €20 total (€10 win + €10 place).

Acca Insurance

Acca insurance is a promotion offered by many Irish bookmakers where, if your acca loses by a single leg, they refund your stake as a free bet. The exact terms vary:

• Minimum number of legs (typically 4 or 5)
• Minimum odds on each leg (often 1/2 or Evens)
• Maximum refund amount (often €10 or €25)
• Which sports qualify (football-only is common; some offer multi-sport)
• Refund as free bet or cash (almost always free bet)

Acca insurance only pays out when exactly one leg loses. If two or more legs lose, nothing is refunded. It also does not pay out on bet builders or same-game accas at most bookmakers, though this varies. If you place a lot of accas, the bookmaker offering the broadest acca insurance is often worth a second account specifically for that bet type.

Cash Out on Accumulators

Cash out lets you settle your accumulator early, either to lock in a profit before the final leg runs or to recover some stake when a loss looks likely. The cash out offer changes constantly based on the live odds of the remaining selections.

A typical scenario: you have a five-fold football acca and four legs have won. The final leg is Chelsea to beat Everton, and Chelsea are 1-0 up with 20 minutes left. Your bet currently sits at, say, €210 potential returns. Cash out might offer €170 to settle now, based on Chelsea’s in-play odds to hold on. Take the cash out and the bet is closed. Let it run and either collect €210 if Chelsea hold or nothing if Everton score twice.

Cash out is convenient but rarely pure value. Bookmakers build a margin into the offer, so the cash out figure is always slightly worse than the true implied odds of the remaining leg. It is a useful tool for protecting a big return when nerves get the better of you, less useful as a habit. Partial cash out, where you take half the stake and let the rest ride, is a middle-ground option some bookmakers offer.

Accumulator Bonuses (Acca Boosts)

Many Irish bookmakers run standing promotions that boost winning acca returns by a percentage based on the number of legs. Typical boost ladders look like this:

• 4-fold: 5% boost
• 5-fold: 10% boost
• 6-fold: 20% boost
• 7-fold: 30% boost
• 8-fold and above: 50% boost

Qualifying terms usually include minimum odds per leg (1/2 or Evens is common), a football-only restriction, and a cap on the maximum boost. These boosts stack meaningfully over time if you are a regular acca bettor, and they are worth checking before you decide which bookmaker to place a weekend acca with.

Non-Runners on Horse Racing Accumulators

Non-runners on horse racing accumulators are handled automatically: the non-running leg is removed from your bet and the remaining selections form a smaller acca. A five-fold acca with one non-runner becomes a four-fold. The odds recalculate to exclude the non-running leg, so your potential returns drop but the bet is not voided outright.

This also applies to each-way accumulators. If a non-runner comes from your Lucky 15, the bet reshapes around the remaining three selections – four singles, three doubles, three trebles, and one treble stays intact (becomes the new multiple). Always check the bet has recalculated correctly on your bet slip before the races run.

Max Payout Limits

Every bookmaker sets a maximum payout limit per bet. For football and most mainstream sports this is typically €250,000 to €1 million. For tennis, darts, and niche sports, limits can be lower. If your acca returns would exceed the cap, the bookmaker pays out the maximum and nothing more, regardless of what the actual calculated returns would be.

This matters most on very long accas (8 legs or more) and on full cover bets where the combined returns from dozens of separate bets can stack up. A €5 Goliath with 8 heavy favourites all winning can exceed the max payout at some bookmakers. If you regularly place big accas, check the small print on max payouts before betting, or split your stake across two bookmakers to get around the cap.

Example Accumulator

Here is a five-fold football acca to show how one loss breaks the whole bet.

Selection	Match	Result
Arsenal to Win	Arsenal vs Tottenham	Arsenal Win
Millwall to Win	Millwall vs Brighton	Millwall Win
Watford to Win	Derby vs Watford	Watford Win
Colchester to Win	Colchester vs Walsall	Colchester Win
Southend to Win	Southend vs Fleetwood	Southend Lose

Four of the five selections have come in. A Lucky 15 or Yankee on the same selections would pay out handsomely (six winning doubles, four winning trebles, and the four-fold accumulator with Arsenal, Millwall, Watford, and Colchester). A straight five-fold acca collects nothing. This is exactly the trade-off full cover bets are designed for: you pay more in stake up front to still get a return when a single leg fails.

Common Mistakes Acca Punters Make

• Adding too many legs: every extra selection feels like it improves the return, but each one cuts the probability of the whole bet winning. Four to six legs is the sweet spot for most accas; beyond that the odds look attractive but the strike rate drops off a cliff.
• Mixing heavy favourites with obvious long shots: the long shot usually loses, which breaks the whole acca. If you want to include an underdog, put it in a smaller acca or a separate bet.
• Ignoring kick-off times on cash out: you cannot cash out once a match finishes if all your other legs are still to play. Time your cash out for when the live odds are strongest, not at the last moment.
• Not checking max payout: nothing feels worse than a 20-fold acca landing only to find out your €50,000 return is capped at €10,000.
• Forgetting about acca boosts: the same bet at two bookmakers can differ by 10-20% on final return once boosts and bonuses apply. Pick the one running the best boost on your leg count.
• Chasing losses with bigger accas: after losing a seven-fold, doubling the stake on a nine-fold is not a strategy, it is a trap. The probability of the bet landing just got smaller.

Accumulator Tips

• Shop for prices on every leg. On a five-fold, a 10% better price per leg compounds into roughly 60% more total return.
• Pick selections you would bet on individually. An acca is only as good as its weakest leg. If you would not back a team at its current price as a single bet, it should not be in your acca either.
• Use acca insurance to your advantage. Stack your acca with five or six legs so that acca insurance covers any single-leg loss, rather than placing a safer four-fold without insurance.
• Consider Lucky bets instead of straight accas when you have strong feelings about 3-4 selections. The extra cover can be worth the bigger outlay.
• Set a stake budget. Accas should be a small percentage of your monthly betting, not most of it. The variance is high.
• Cash out partials on live accas. Taking half the stake out when you have four legs home protects the bankroll and leaves upside on the final leg.

Betting with Licensed Bookmakers

All the bookmakers we recommend are licensed to accept bets from Irish customers. Ireland’s gambling market is regulated, and reputable operators hold licences from Irish and international authorities. Always bet with a licensed bookmaker to ensure your funds are protected and you have access to dispute resolution if anything goes wrong.

Summary

A standard accumulator is a high-reward, low-probability bet where every leg must win. Four to six legs is the practical sweet spot. Full cover bets like Yankees, Lucky 15s, and Heinzes give you cover on partial wins for the cost of a larger stake. Each-way accumulators add a place component useful for horse racing. Acca insurance, acca boosts, and cash out are the three promotional tools worth understanding before you place a big acca.
