What Does 21.5 Mean In Tennis Betting

21.5 is a type of bet that you could take for a tennis match. The number has to do with the over/under on the number of games that are played in a particular tennis match. In tennis, this bet is commonly referred to as a total games bet.

During any given tennis match, there will be an over/under number set on the number of games that will be played during a tennis match. Typically, if the feeling is that the match will remain close throughout, then the over/under number will be larger as the number of games will be higher in a close match. However, if the match is projected to be a blowout, then the over/under amount will be lower as the game would end quickly. 

The given 21.5 amount is the over/under for a specific match. If you were to bet on the over 21.5 for this match, then you would be saying that you think the number of games in this match will be 22 or more. However, if you were to place a bet on the under 21.5, you would be saying that you think that the number of games in this match would be 21 or less.

Examples

An example of a match game total going over 21.5 would be a score of 6-4, 3-6, 6-1. In this case, there are 26 total games played, so the over 21.5 games would be hit. Since the gamer total after the first two sets is 19 and a third set is being played, the over would automatically win before the third set even begins. This is because the minimum number of games played in a set is six, and six games would be enough to hit the over.

If the score was 6-2, 6-1, only 15 games would be played, making the under the winning bet. In a lot of cases, under and over bets are contingent on whether or not the match goes to a third set. In some cases, however, if the scores in each set are very lopsided, the under can still win in a third set.

Conclusion

There can only be a maximum of 13 games in a set if a tiebreak is played for a final score of 7-6 or 6-7 score. If two sets in a match go to a tiebreak, that would be well over 21.5 games.

If you believe the match will be close and there will be tiebreaks, you will want to take the over 21.5 bet. If you believe the match will end in straight sets, then take the under 21.5 bet.

FAQ

What does a total games bet mean in tennis?

In tennis, a total games bet is a bet where people can decide whether a tennis match will go over or under a certain number of games played. Matches that are expected to be competitive will usually have a higher game total, whereas an expected blowout will have a lower total. In many cases, the game's total bet will be decided based on whether a tiebreaker set is played. An example of a game's total bet may be 20.5, meaning a person can bet on whether they think the match will have over or under 20.5 total games.

What does over 36.5 mean in tennis?

In tennis, over 36.5 is a bet that would need the match to play 37 or more total games to win. While it is possible for a best-of-three match to reach 37 total games, it is very rare. Because of this, a game total of 36.5 would usually only be used in a men’s Grand Slam tournament where it is best-of-five. If the score was 6-4, 3-6, 7-6, 6-2, then the over 36.5 bet would win as there were 40 total games played. 

What does +4.5 mean in tennis betting?

In tennis betting, +4.5 would mean that a player must lose by four games or less. Similar to other sports, a bet with a “+” or “-” symbol indicates spread betting. In tennis, spread betting is mostly used for games, and a total of +4.5 would be given to a heavy underdog. If the score was 6-4, 6-4, the underdog would still only lose by four sets, meaning that the bet would hit. The player who is “+” games would not receive any better payout for winning the match outright. In many cases, sportsbooks will offer alternate game spread lines with varying odds.
