What Does -0.5 Mean in Bets?

BET, short for “Betting and Gaming,” is the industry standard for reporting gambling activity. It is used widely across the industry and is supported by the vast majority of betting sites.

The most popular uses of BET are for placing bets on sports events, such as football, basketball, and hockey. In the UK, for example, you can bet on anything from horse races to who will be the next prime minister. In mainland U.S. wagering markets, you can typically place a sports bet, a casino game, or a combination of both. However, throughout the rest of the world, you can only place bets at designated sports bookies, which the government has deemed legal and regulated. The following explains the meaning of -0.5 in BET, along with several other common symbols used in gambling.

BET Code Meaning

The numerical codes of the various sports and gaming events are listed in a table that can be found here. The codes for each event correspond to the following list:

  • American Association of Advertising Agencies (4-Braille System)
  • American Advertising Federation (AAF)
  • Association of Advertising Agencies (4A’s)
  • Automobile Association of America (4O’s)
  • Brand Name Institute (BNI)
  • Canadian Advertising Association (4A’s)
  • National Association of Advertising Agencies (4A’s)
  • New Zealand Advertising Association (4A’s)
  • Royal Academy of Arts (KA)
  • Swedish Advertising Association (SSA)

BET stands for “Betting and Gaming,” as mentioned by Wikipedia. But what does that mean in English? The numerical codes listed above are used to identify particular sports or gaming events, and they all start with the letter “B”. Therefore, when you see “B” followed by a numerical code, that means the following:

  • Betting
  • Gaming
  • Events

For example, in American football you would use the code 15 as shorthand for the following:

  • Betting on the game
  • American Football
  • Events
  • in the U.S.

This would be represented in shorthand as follows:

  • B15
  • A14
  • S8
  • U.S.

Doing business in multiple countries means you would represent the above as follows:

  • B15
  • A14
  • S8
  • U.S.

When you see three sets of four numerals in a row, it is a representation of a wager. For example, in poker you would use the code 3, 3, 3, 3 to indicate a $3 ante, $3 blind, $3 three-wheel, and $3 royal pot bets. These are simply different representations of the same bet, and they all have the same dollar value.

This is also true of other betting and gaming codes, such as 1-2-3 for a $2 side bet in football, or 4-6-8 for a $6 top prize in a carnival game (although these are increasingly uncommon given the widespread use of number blocks).

What Is The Most Popular Use Of BET?

The most popular use of BET is for placing bets on sports events. It is typically used with odds that are adjusted by taking into account the point spread (the number of points by which one team is favored in a game) of the event. For example, if the spread for an American football game is 3.5 points, the odds of the home team winning would be 7/4 (1.75 to 1), and the odds of the away team winning would be 4/7 (1.33 to 1).

Placing a bet on an even number of points (2, 4, 6, or 8) would mean you are expecting the number of points to be even, and it would also mean you are assuming that neither team will have an outstanding performance. In that case, it would be safest to select the side with the worst record. This may not be the most exciting use of BET, but it is the safest.

The following table lists the various sports and gaming events covered by BET, along with their corresponding codes:

Basketball is another game that has been around for a long time and has been played internationally for many decades. In the U.S., college basketball and professional basketball are the most popular sports – and together they are often referred to as “the game.”

Basket-ball is particularly popular in the U.S., where the National Basketball Association (NBA) is considered to be the premier professional basketball league. The following codes are used to identify particular forms of basketball wagering:

  • NBA
  • WNBA
  • ABA
  • NBDL
  • ISBA
  • CBA
  • CPBA
  • PBA
  • BLBA
  • DBL

Many people also bet on the daily fantasy sports (DFS) that are becoming increasingly popular. Daily fantasy sports are basically like playing fantasy football or baseball, but with an additional element of daily betting. This is also reflected in the table above, where the DFS code is listed after the corresponding event. For example, on a fantasy football site you might see “Basketball – NBA” or “Basketball – NCAA” with odds that are adjusted based on the daily performances of the players in real life.


American football is one of the most popular sports in the world, and it has been played professionally for nearly a century. The International Federation of Football (FIFA) originally started tracking and reporting football world statistics in 1922. They started with 18 member countries and have since expanded to include over 200, with more countries applying to join every year. The following codes are used to identify football wagering:

  • NFL
  • NPL
  • AFL
  • CAFL
  • LFL
  • USFL
  • PSL
  • MLS
  • RNL
  • CTFL
  • Pegasus League
  • FSL

Many people also bet on the Premier League, La Liga, and other major soccer leagues around the world. Do keep in mind that the majority of bets are placed on games featuring teams from the U.S. As a result, the majority of codes listed above are associated with American football, baseball, and basketball. But that doesn’t mean you can’t find sports wagering options for other leagues as well.


Hockey is also another popular sport in North America and has been around for almost a century. The first hockey league, the National Hockey League, was founded in 1917 and has since expanded to include teams in many different cities across the country. The following codes are used to identify hockey wagering:
