Singles, Doubles and Trebles Explained

The short answer

A single contains one selection. A double links two selections; a treble links three. In an ordinary all-to-win multiple, every remaining leg must win for a winning return. Three singles and one treble are different bets with different costs and outcomes.

Count bets separately from selections

Three £2 singles cost £6. One £2 treble costs £2, even though it contains three selections. Three £2 doubles drawn from three selections cost £6 because there are three separate combinations.

The unit stake alone cannot tell you the total outlay on a combination bet. Read both the number of constituent bets and the total cost on the accepted receipt.

Worked example: all three selections win

Take hypothetical independent selections at decimal 2.00, 3.00 and 1.50. A £2 double on the first two returns £2 x 2 x 3 = £12. A £2 treble returns £2 x 2 x 3 x 1.5 = £18. These are ordinary cash returns including the original stake.

Three separate £2 singles on the same selections return £4 + £6 + £3 = £13 if all win, against £6 total cost. The treble and singles cannot be compared without acknowledging their different outlay and settlement conditions.

A losing leg changes the multiple

If the middle selection loses, the ordinary treble loses, even if the other two win. With the three singles, the winning first and third selections still return £7 in total against the £6 cost. Different combinations distribute outcomes differently; none removes exposure to loss.

For selections from the same event, outcomes can be related. A bookmaker may reject a conventional multiple or price it through a bet builder. Multiplying the displayed single prices is not a reliable way to calculate a builder quotation.

A void leg is not the same as a losing leg

Under common multiple settlement, a void leg is removed using a multiplier of 1.00, reducing a treble to a double. Read the operator’s rules for the actual market; specialist builders and promotions can use different treatment.

A reduced multiple may no longer meet a minimum-leg promotional condition. Settlement of the cash bet and entitlement to an extra reward should be checked separately.

Common questions

Does a treble require three winning selections?

For a conventional all-to-win treble with three valid legs, yes. Void legs and specialist products require the relevant settlement rules.

Can I multiply odds from the same match?

Not reliably. Related outcomes can be restricted or receive a combined price through a builder rather than ordinary multiplication.
