In-play betting involves wagering on the outcome of a sporting event. The odds and probable outcomes are agreed upon by betting establishments. You can bet on the total number of goals scored, yellow cards thrown, and half-time scores. You can also bet on the player who scored the winning goal. The structure of in-play betting is different than conventional betting, but its features remain the same.

In basketball, the tempo of the game is very important. If a team is sluggish, the over/under will be higher. Likewise, the underdog will have a lower total if they are facing a left-handed pitcher. The weather can also affect the betting outcome, especially when outdoor sports like baseball and football are involved. If a team plays in an inclement weather, the total is likely to be lower than usual.

Spread betting is another type of wager that uses a point spread to even out an uneven game. This means that a favorite will have a negative spread, while the underdog will have a positive spread. A bettor will need to determine how strong each team is and decide whether to back a favorite or underdog. The favorite is expected to win by a certain number of points to win, whereas the underdog will be able to win even if it loses.

Betting odds vary between countries. In Europe, they are referred to as decimal odds and fractional odds. In the US, they are commonly referred to as money line odds. Decimal odds, on the other hand, are proportional to the stakes. They represent the amount won or lost for every dollar staked.
