    What is a Goliath?

    A Goliath is the largest standard named full-cover bet — 247 bets across 8 selections covering every combination from doubles to the eight-fold. No singles. A £1 Goliath costs £247. Most are placed at very small unit stakes like 10p or 20p.

    Is a Goliath worth it?

    At £247 per unit, you need several winners at decent odds to recoup. With 4+ winners at 3/1+, doubles and trebles start generating meaningful returns. With 6+ winners, higher-order combinations produce substantial payouts. But 2–3 winners at typical odds rarely covers the cost.

    Why 247 bets?

    With 8 selections and bet sizes from 2 to 8, the total combinations are C(8,2) + C(8,3) + C(8,4) + C(8,5) + C(8,6) + C(8,7) + C(8,8) = 28 + 56 + 70 + 56 + 28 + 8 + 1 = 247. This is the largest standard named full-cover bet — anything larger uses custom round robin formats.

    Goliath returns by winner count

    With 2 winners: 1 winning double. With 3: 3 doubles + 1 treble. With 4: 6 doubles + 4 trebles + 1 four-fold = 11 winning bets. With 5+, returns escalate rapidly as higher-order combinations start paying out. The eight-fold accumulator alone can produce extraordinary returns if all 8 selections win at decent odds.
