Find out how a combo bet works in sports

One of the most popular betting types among Portuguese bettors is the combined selection. Also known as multiples, combined bets link selections on the same ticket to increase the potential return. Currently, this option is available on most sports betting platforms, and some even offer ready-made combinations.

Especially in football, when there are many matches at close times, bettors like to combine predictions to get more return with a low investment. Depending on the size of the selection, it can be quite difficult to win, but that's exactly why the potential gains are high. Understand how they work and how to improve your results with combined bets in this guide.

Combined Bets: Definition

This type of bet involves not just one sporting event, but at least two to configure a combined bet. The name comes from the combination of odds, meaning all selections need to be victorious for there to be a profit. This feature is fully regulated by the SRIJ in Portugal, but it is recommended to always operate through licensed platforms.

The most relevant aspects of combined selections are:

Combination of odds: The selection involves more than one event or market on a single betting ticket;
Multiplication of odds: The odds are multiplied among themselves, thus generating the highest potential return;
Higher risk: Considering that all predictions must be correct at the end of the events for the bet to be successful, there is a high risk involved.
Different types: Combined bets can be doubles, triples, and multiples. The markets and sports do not need to be the same, nor the times.

It is also important to consider that platforms usually impose restrictions and limitations on combined bets. Generally, it is not allowed to exceed 20 selections, and some houses may limit access in case of many consecutive combinations. It is also worth remembering that events that contradict each other are canceled within the selection, as well as markets that repeat.

Examples of Combined Bets

Before providing examples of combined bets, it is worth remembering what constitutes the opposite of this. Well, the opposite of a combined selection is a single bet, where only one result matters. An example of this is a bet on Porto FC's victory against Gil Vicente in a particular game. If Porto wins, the bet is successful; in case of a draw or loss, the bet is lost.

The concept of combinations, however, involves more selections. So using the example, besides bets on Porto FC, it would also be necessary to place bets on other events. From the moment a bettor inserts two selections on the ticket, it already constitutes a combined sports bet.

See examples of combined selections below:

Victories of Porto and Sporting;
Victory of Porto, over 2.5 goals in the Estoril x Braga game, and a draw between Moreirense x Famalicão;
“Both score” or “Over 1.5 goals” in events A, B, C, D, and E.

Football is the favorite sport among Portuguese bettors, but combined selections can be made in any other sport. Bettors are making selections with multiple modalities, including.

Enter the amount. Through the betting ticket, enter the amount and confirm the bet.

To place a combined bet, you don't need to enter the amount and confirm; just keep selecting the events and markets you want to bet on. The selections are automatically multiplied on the betting ticket.

How are the Gains in Combined Bets?

To understand how to calculate combined bets, it is necessary to consider that it is a constant multiplication account. See a practical example below:

Example: Odd 2 in a draw; Odd 3 in a win; Odd 1.7 in both score;
Calculation: It is not a sum; in this case, it would be 2 x 3 x 1.7;
Final probability: The result of the combined odd, then, would be 10.2;
Potential profits: The investment would be multiplied by 10.2.

Considering a 4 3 2 betting method for combined selections, this multiplication would give 24 in odd. With a €10 bet, the potential return is €240.

What Predictions are Possible for Combined Bets?

The predictions available to compose a combined bet are not exactly the same on all platforms, varying according to the betting house and the type of sport. Still, there are markets that stand out for being widely accepted and frequently chosen by bettors, being present on the vast majority of sites.

Among the most common are:

Game result: bet on the outcome of the match, considering a win for one of the teams or a draw;

Both teams score: selection based on whether or not goals are scored by both sides;

Total goals/points: prediction if the final number will be above or below the defined line.

It is important to note that many betting houses impose specific rules for combinations with additional bonuses. In several situations, the odds boost is only applied when all choices belong to the same market. Thus, to benefit from an increase in odds, it may be necessary for all selections to be, for example, of the “both score” type.

What are the Different Types of Combined Bets?

In addition to the individual markets that make up a combined bet, there are different formats and variations of this type of ticket. Below are the main variations available at betting houses, explained simply and practically:

Triple: Includes three events on the same ticket, increasing the risk and also the possible return;

Multiple: Combination formed by four or more selections;
Different sports: Gathers events from different modalities on the same ticket;

Same market: All choices belong to the same type of market, such as final result or total goals;

Distinct markets: Combines selections from different markets, including statistics and other indicators.

Besides these variations, some platforms offer the option to create personalized bets. In these cases, the selections are made within a single event, maintaining the usual functioning of odds multiplication and gain calculation.
