The crucial difference between sports betting and casino gambling is that no amount of knowledge about slot machines or the roulette table will allow you to always stay ahead of the house, unless you're some kind of gifted savant - and as soon as the casino realises you are, they'll ban you anyway. However, with sports gambling, you can bring to bear all your knowledge of the game, the teams and the players on making informed, calculated bets and thereby potentially make a considerable amount of money. For instance, thousands of people around the world stand to make some good money in Soccer World Cup Betting this year.

Whilst at a casino there are fixed betting rules, many sports bookmakers will along you to bet on just about anything. In roulette you can only bet on the numbers or color that the ball will land on, not how many times the ball will go around the wheel, for example. With a football game you can bet on the final result, the half-time result, who will score the first touchdown, and so forth. There are even a range of more outrageous proposition bets that you can make, such as how many times the head coach will throw his hands up in the air in despair! If it can be bet on, chances are there will be someone willing to take your bet.

You can also adjust your bets during the game, taking into account the action that has already occurred. Of course the odds will change accordingly, but the opportunity is available to you. At the roulette table, once the ball has entered the wheel, you cannot change your bets.

A final difference is that you can place sports bets remotely. You can be watching the game at home, while placing bets via the internet. This is illegal when it comes to casinos. You have to physically be on the casino property in order to place any bets.
