Single bets explained
A single bet is one selection on its own. How returns work, how it differs from doubles and trebles, and when a single is the clearer stake.
On this page
A single bet is one selection on its own. You pick a price, stake an amount, and settle that one outcome. If it wins, the return is stake × decimal odds. If it loses, the stake is gone. No other leg has to land.
How the return works
| Stake | Decimal odds | Result if it wins | Profit |
|---|---|---|---|
| 10 | 1.50 | 15 | 5 |
| 10 | 2.00 | 20 | 10 |
| 10 | 3.50 | 35 | 25 |
Profit is return minus stake. At even money (2.00) you double the stake when you win and lose the stake when you do not. That is the cleanest picture of risk in betting: one number, one outcome.
Singles versus doubles, trebles and accumulators
| Bet type | Legs that must win |
|---|---|
| Single | 1 |
| Double | 2 |
| Treble | 3 |
| Accumulator | 4+ (usage varies by bookmaker) |
Each extra leg multiplies the price and multiplies the ways to lose. A treble built from three 2.00 prices pays 8.00 and needs all three to land. Three separate 2.00 singles need only one win each to pay something, and they keep the losing legs visible. We walk through the multi maths in accumulator odds explained and treble betting explained.
When a single is the clearer stake
A single matches how BAI8 publishes research: one fixture, one chance, one best price, one edge. If our Desk card on Pau vs Nantes shows Pau at 48.5% with a 3.10 price, that is already a single-shaped claim. Folding it into a four-fold with three other edges hides which leg failed when the ticket loses.
Singles are not "safer" in the sense of rarely losing. A fair 2.00 single loses about half the time. They are clearer: the result maps to one estimate. Whether the price is worth taking is a separate question, covered in expected value in betting and what a positive edge actually means.
What this does not tell you
It does not say you should only bet singles. It does not size a stake for you. It explains the simplest bet type so the rest of the ladder makes sense.

Common questions
What is a single bet?
One selection settled on its own. If it wins, you are paid the stake multiplied by the decimal odds. If it loses, the stake is gone.
How is a single different from a double or treble?
A double needs two selections to win. A treble needs three. A single needs one. Combining legs multiplies prices and multiplies ways to lose.
Are singles safer than accumulators?
They expose you to one estimate instead of several. They are not safe. A 2.00 single still loses about half the time at a fair price.
Does BAI8 recommend singles?
BAI8 publishes one fixture at a time with a chance and a price. That shape matches a single better than a multi, but it is still an estimate, not advice to stake.
