Frequently Asked Questions
What is a Goliath bet?
The Goliath is the biggest of the standard named system bets — 247 bets spread across 8 selections. It packs in every combination from doubles right up to an eight-fold accumulator, with no singles.
What does a Goliath cost?
A Goliath costs 247 times your unit stake. At £1 per bet, for instance, that’s £247. It’s a serious outlay, so you’ll want real confidence in your selections.
How many winners does a Goliath need?
At least 2 winning selections to return anything, since the smallest bets are doubles. In practice you’ll usually need 3-4 winners at decent odds to turn a profit against the large total stake.
Is a Goliath bet worth it?
A Goliath can pay off when you’re confident across several selections. The upside is you don’t need all 8 to land — even 4-5 winners at good odds can deliver a big return. That said, the 247-unit stake means you need substantial returns just to come out ahead.
