What is a treble?

A treble combines three selections into one bet. All three odds multiply together, and all three must win to pay. It offers a bigger return than a double but is harder to land — and if you'd like partial winners to still pay, the same three selections in a Trixie or Patent do exactly that.

Worked example

Three selections at 2.00, 2.50 and 3.00, staking €10:

  • Combined odds = 2.00 × 2.50 × 3.00 = 15.00
  • Return = €10 × 15.00 = €150 (a €140 profit)
  • But if any one of the three loses, the return is €0.

Frequently asked questions

What is a treble bet?
A treble combines three selections into a single bet. The three decimal odds multiply together, and all three selections must win for the bet to pay. If any one loses, the treble loses.
How is a treble bet calculated?
Multiply the three decimal odds, then multiply by your stake. Three selections at 2.00, 2.50 and 3.00 give 2.00 x 2.50 x 3.00 = 15.00, so a EUR10 treble returns EUR150.
What happens if one selection loses?
The treble loses entirely - all three must win. A full-cover bet like a Trixie or Patent would still pay on the doubles or singles, but a straight treble is all-or-nothing.
What is the difference between a treble and a Trixie?
A treble is one bet needing all three winners. A Trixie uses the same three selections but is 4 bets (3 doubles + 1 treble), so two winners already return something. The Trixie costs more but is more forgiving.
What is an each-way treble?
An each-way treble is two bets (a win treble and a place treble), costing twice the stake, and pays on the place part if your selections place rather than win.
