Bundesliga Betting Sites Overview

The Bundesliga has played a key role in German football since its creation in the second half of the twentieth century. Although the Bundesliga has faced its fair share of challenges throughout the years, it is now one of the largest leagues in the world.

Between its sheer popularity and the relatively inexpensive ticket prices of Bundesliga matches, the league enjoys excellent attendance at stadiums. Additionally, lots of fans tune in to enjoy the games on TV, radio, or over the internet, and many of the fans in question are passionate punters as well. Among these individuals are passionate Bundesliga bettors.

History of the Bundesliga

The creation of a proper national football competition in Germany took quite some time. The idea had been pitched multiple times, but to no success. A key figure who wished to see the creation of a national league was Sepp Herberger. He had suggested the league’s creation multiple times, including after his team’s victory in the 1957 FIFA World Cup. Unfortunately, it would not be until the 60s that things would finally take a turn for the better.

Creation and First Season

The year 1962 was somewhat polarizing for German football. The German National Team’s performance in the 1962 FIFA World Cup had been underwhelming at best, with the team only reaching the quarter-finals. The event was a sign that the semi-professional landscape of Germany’s football clubs would continue to be a problem, as players were simply not paid enough to dedicate themselves fully to the sport.

This very event, however, was the final push necessary to finally convince the DFB that the Bundesliga football league was an absolute necessity. Thus, the Bundesliga was born, and plans to turn German football into a true professional sport were set into motion.

Setbacks

Although its very creation was a feat in and of itself, the Bundesliga did have to face its fair share of challenges. A notable event was a scandal that occurred in 1965, when it was revealed that clubs were paying players more than what was permitted by the DFB. Another issue arose in 1971, although that situation was centered around match-fixing. In both cases, the perpetrators were punished swiftly. Although problematic in their own right, these occurrences highlighted that the DFB could still do better to improve the professionalism of the league.

Thankfully, neither event did much to harm the league long-term, and West Germany managed to win the 1974 World Cup. The two most prominent teams in the 70s and 80s were Bor. Mönchengladbach and Bayern München.

The Modern Bundesliga

The Bundesliga continued to prosper in the 90s, and in 1998, the 50+1 rule was introduced. It dictates that private investors cannot own more than 49% of a club.

As for the teams, Germany’s reunification led to an expansion of the league from 18 to 20 clubs. The East German teams that would participate in the Bundesliga during the 1991–92 season were Hansa Rostock and Dynamo Dresden, and the team that won that season was FC Kaiserslautern. Bayern München would win a total of four seasons in the 90s, but in general things were still fairly balanced back then, and the following teams would also come to win either once or several times:

• Werder Bremen
• VfB Stuttgart
• Borussia Dortmund

The Basics of Online Soccer Betting

Nowadays, the soccer betting landscape has changed quite a lot. We no longer live in times when land-based bookies are at the height of their popularity. Punters can now wager from the comfort of their own homes, and the plethora of information and sportsbooks on the web has made wagering a very accessible pastime even for the busiest of modern-day individuals.

Modern punters have an ample choice of bookies to pick from. Furthermore, they can also access information regarding all there is to betting on the web. The information is so plentiful, in fact, that things might be somewhat overwhelming, which is why we will guide you through the basics of Bundesliga betting.

The Bankroll

As entertaining as sports betting can be, it is no secret that it can pose a danger to a punter’s savings if they lose control. Something that can greatly help in combating the dangers of reckless betting is bankroll management. A punter’s bankroll is the budget they can work with when they wager on sports, and the amount of money you use as your bankroll must never exceed how much you can afford to lose.

As for how you can manage your bankroll beyond setting aside a given amount of money for betting, there are strategies that can make the task easier. These betting systems will never guarantee that you will win or profit off of wagering on football, but they will assist you in controlling your betting habits.

The Martingale and the Anti-Martingale are such strategies. The Martingale is a negative progression system that dictates that your stake must be doubled after a loss. When you win, the next bet must be halved, or it needs to return to being one base unit. As for the Anti-Martingale, it is in reverse, and you need to multiply your stake by two after you win.

The Paroli is a system that resembles the Martingale. The difference here is that if you win three times, you must return to your base stake. It is, all in all, a more conservative and safer strategy.

The final strategy we will look over is flat betting. It is the simplest and, thus, most effective option for the majority of bettors. As suggested by its name, the flat betting strategy involves wagering the same percentage of your bankroll each time you place a bet.

Soccer Bet Types

Punters should also be familiar with the bet types you can place at online bookies. Otherwise, the listings at sportsbooks will look incredibly confusing. The first types of bets that tend to be quite popular among punters are win bets or bets involving the moneyline. The most popular types are:

The three-way moneyline, for instance, is a wager where you have three bets to pick from. The first two outcomes involve either the first or the second team winning, while the last option is the draw. In contrast, the two-way moneyline does not give you the option to wager on a draw occurring. If the game does end in a tie, the sportsbook will refund you your stake.

Handicapping is another popular bet variation. Here, the underdogs are given an advantage, and wagering on them can be successful if they do not lose by more points than listed, while the favorites are handicapped and must cover the spread for you to win:

• Borussia Dortmund -1.5: 2.13
• Werder Bremen +1.5: 1.83

The Odds

The final aspect of Bundesliga betting that will allow you to view sportsbook listings with ease is the odds. They determine how much money you stand to win based on how much you wager:

1. Decimal odds are shown via decimals, and the team with the lower decimal number is the favorite. To know how much profit you could make from a $5 bet, you can use the following formula: Profit = (decimal odds x stake) – stake = 7.8 – 5 = $2.8
2. Fractional odds, on the other hand, how much you can win per $1. In the case above, fans of FSB Mainz will win $11 for every $20 wagered.
3. Finally, American odds make it exceptionally easy to see the underdog and favorite role of each team. If you bet on Mainz, you need to bet $180 to win $100, while betting $100 on Augsburg will net a $148 win.

FAQ

1. How many different teams have won the Bundesliga so far?

   At the time of writing, there are 12 different clubs that have become Bundesliga champions. Bayern München is the team that has won the most championships thus far, and they have won a total of 32 times.

2. What are accumulator bets?

   Accumulator bets, which are often referred to as accas, are multiple bets combined into one. The bets that make up an accumulator are referred to as legs or selections, and the legs in question must be from different matches. The odds of the selections are multiplied by one another, and all of the outcomes in question must come true for the acca bet to win.

3. What will happen if a Bundesliga match I had wagered on gets postponed?

   There are two common outcomes depending on when the game is rescheduled to take place. Typically, rescheduling that results in a delay longer than 72 hours will result in your bet being declared void, in which case you will receive your stake back.

   If the delay is less than 72 hours, the bet will usually stand and settle naturally when the game takes place. There are sportsbooks that will always void your bet when a postponement occurs, however, so when in doubt, look for this information on your sportsbook’s FAQ page.

4. Are proposition bets worth placing?

   This is strongly dependent on each individual punter’s preferences, what they aim for, and the prop bet in question. For instance, punters who like to test their knowledge regarding a matchup should only go for skilled props like goal to be scored in the first half, as these bets lend themselves well to analysis. For such a punter, a fun prop, that is, a proposition bet where the outcome is only a matter of luck, would not be worth it. As for recreational bettors who wager because it is exciting, both skilled and fun prop bets can be worth it due to the entertainment factor

5. Why do the odds of in-play bets change so quickly during live Bundesliga games?

   Odds change based on the expectations sportsbooks and punters have regarding the outcome of a specific bet. When a game is underway, every occurrence on the field can affect the odds, which is why the odds tend to fluctuate quite a bit during in-play.
