Single
One outcome, one price. For example, €10 at 1.85 returns €18.50 if the outcome happens. The cost of the bet is the margin of that one market.
Accumulator
Two or more selections on one slip (in Greek, a «παρολί»). Every one has to come in. The odds multiply, e.g. 1.85 × 1.90 × 2.10 ≈ 7.38. The return looks big, but the chance of all three coming in is small, and the margin of each market stacks up.
| Selections (example) | Combined odds | Priced probability |
|---|---|---|
| 1 (1.85) | 1.85 | 54.1% |
| 2 (1.85 × 1.90) | 3.52 | 28.4% |
| 3 (1.85 × 1.90 × 2.10) | 7.38 | 13.5% |
System bet
A system bet plays many combinations of your selections, e.g. all the doubles from three matches (3 lines). You can miss one selection and still get a return, but you pay for every line: for example, at €2 a line the slip costs €6.
The bet type doesn’t change the uncertainty
Single, accumulator or system: in every case the result of the match stays uncertain. The Greek Commercial Communication Regulation (Ministerial Decision 79292/2020) bars ads from giving the impression that the result can be foreseen or controlled (Article 8.3.7), or that playing more often improves results (Article 8.3.8).
Frequently asked questions
Why do accumulators have such high odds?
Because every selection has to come in. The odds multiply, but so do the margins.
Does a system bet reduce the risk?
It lets you miss some selections and still get a return, but it costs you more lines. Your total stake goes up.
Which bet type costs the least?
A single, because you pay the margin of just one market. No bet type changes the fact that the result is uncertain.
