Bet types: what each bet actually buys
Before choosing an event, it pays to choose the type of bet. The same prediction can be cheap or expensive depending on how you play it. Here are the main types in our own words, with an eye on the margin the bookmaker keeps.
Online sports betting is licensed country by country. Whether you may bet with Woos depends on the law where you live and on whether the operator holds a licence that covers it: check before opening an account.
Single
A bet on one outcome. The margin is that of the chosen market and the result depends on one event. It is the most transparent bet: you know exactly what you risk and what you pay.
Accumulator
Several outcomes in one bet; it wins only if all are right. The odds multiply, and so do the margins. With three legs at a 5% margin each, the share the bookmaker keeps overall rises to about 14%.
| Legs | Margin per leg | Share kept overall (approx.) |
|---|---|---|
| 1 | 5% | 4.8% |
| 3 | 5% | 13.6% |
| 5 | 5% | 21.6% |
| 8 | 5% | 32.3% |
The table shows why long accumulators are tempting and costly: the advertised price is high, but the share kept grows with every leg.
System bets
A system splits several selections into many smaller accumulators: with four selections, for example, every double. You can win something with one wrong pick, but you pay for more bets. It reduces variance, not margin.
In-play and cash out
In-play bets are placed during the event, with prices updating constantly. Cash out lets you settle early at a price the bookmaker proposes, which includes a margin: closing means accepting a second bet the other way. Not every market or operator offers it.
Handicaps and lines
Handicaps and over/under turn lopsided matches into near-even choices, with prices close to 1.90 on both sides. They make margins easy to compare: two prices of 1.90 mean a margin of about 5.3%.
Specials and outrights
League winner, top scorer, non-sporting events: markets with many outcomes and often high margins, with money tied up for months. Treat them as an entertainment cost, not an investment.
