When a Goliath makes sense — honestly

Every bet inside a Goliath carries the bookmaker's margin, and combining selections multiplies that margin just as it multiplies the odds. A system bet never improves your expected value over the same stakes placed as singles — what it changes is the shape of the outcomes: nothing returns until two selections land, in exchange for cheaper cover than the version with singles. That is a variance choice, not an edge.

The honest way to use one: pick selections that are each positive value on their own (our screener ranks the board by exactly that), keep the unit stake small enough that 247 bets fit your bankroll rules, and check every price before placing — a leg that drifted past fair value weakens every combination it sits in, not just its own single.

Goliath FAQ

What is a Goliath bet?+

A system bet on 8 selections made of 28 doubles, 56 trebles, 70 four-folds, 56 five-folds, 28 six-folds, 8 seven-folds, 1 eight-fold — 247 bets in total, each carrying its own stake. 8 selections: every double through to the eight-fold — 247 bets.

How much does a Goliath cost?+

Your unit stake times 247. At 1 unit per bet the full slip costs 247 units — the calculator shows the exact outlay as you type.

Why doesn't one winner return anything on a Goliath?+

Because the smallest bet in a Goliath is a double, a single winner completes no bet. You need at least two winners for any return — that is the trade-off for spending nothing on singles.

What happens to void selections?+

A void (postponed match, non-runner) is not a loss: every combination containing it is settled at odds of 1.00 for that leg, so doubles become effective singles and so on. Mark a selection Void in the calculator to see the effect.
