What is a Goliath?

A Goliath is the biggest standard full-cover bet: eight selections combined into 247 bets28 doubles, 56 trebles, 70 four-folds, 56 five-folds, 28 six-folds, 8 seven-folds and 1 eight-fold. There are no singles, so you need at least two winners to see a return.

It's the giant of the family — a step up from the Heinz (6 selections) and Super Heinz (7). With 247 bets the outlay is large, so a tiny unit stake is essential: even €0.10 per line costs €24.70.

Worked example

Eight selections, all at odds of 3.00, with a €1 unit stake (€247 total). If all eight win, the 247 combinations return a colossal €65,511 — a €65,264 profit. (That's why real Goliaths use tiny unit stakes.)

More realistically, tap a few selections to Lost and the calculator shows exactly what the surviving doubles, trebles and higher combinations return — the real strength of a Goliath is that partial winners still pay.

Frequently asked questions

What is a Goliath bet?
A Goliath is a full-cover bet on eight selections combining into 247 bets: 28 doubles, 56 trebles, 70 four-folds, 56 five-folds, 28 six-folds, 8 seven-folds and 1 eight-fold. It has no singles, so you need at least two winners for a return.
How many bets are in a Goliath?
247 bets - the largest of the standard named multiples. Because of that, a very small unit stake (e.g. EUR0.10) is common: EUR0.10 x 247 = EUR24.70.
How many winners do I need in a Goliath?
At least two, since there are no singles. With eight selections the returns can be enormous if most or all win, thanks to the huge number of combinations.
What is the difference between a Goliath and a Super Heinz?
A Super Heinz is seven selections (120 bets); a Goliath is eight selections (247 bets). Both are no-singles full-cover bets - the Goliath simply adds an eighth selection and more than doubles the number of bets.
Is a Goliath worth it?
It offers massive upside if several of your eight selections win, but 247 bets is a large outlay, so keep the unit stake tiny. It suits a confident eight-selection racing accumulator where you want partial winners to still pay.
