Goliath calculator

A Goliath is 247 bets across 8 selections — every combination from doubles up to the eightfold. There are no singles, so at least two winners are needed.

How a Goliath works

Structure: 8 selections → 28 doubles + 56 trebles + 70 fourfolds + 56 fivefolds + 28 sixfolds + 8 sevenfolds + 1 eightfold = 247 bets. Total stake is your unit stake × 247 (× 2 if each-way).

The Goliath is the largest of the common full-cover bets — 247 unit stakes (494 each-way). Keep the unit small: at just £1 a line that is £247. One winner pays nothing; returns rise steeply as more selections land. Per-line detail is summarised by group here given the 247 lines.

This is a returns calculator, not a prediction. It shows what a Goliath would pay for the odds and results you enter — it does not forecast outcomes and we do not sell tips. A winning line's return is your unit stake × the combined decimal odds of that line.
