The Martingale Betting system is one of the most popular betting systems used in casinos. You may think that you haven't heard of it, but chances are someone told you about this at least once.

The Martingale system works best on Roulette or blackjack. It has the player double his bet each time he losses, until he finally wins, at which point he has recouped his losses and gained his first bet as profit.

This betting system has been popular in land based and online casinos alike, but it does have a serious flaw that players should be aware of. When this betting system became very popular in the 17th century, casinos were quick to respond by incorporating betting limits into the games. This is why there's a minimum and maximum bet limit on nearly all casino games.

Most betting system can 10/200, which may seem like a lot of breathing room, but it really isn't. In a minimum $10 and maximum $200 table, it would take only 5 consecutive losses until you hit the table limits, and then you've really lost.

If 5 consecutive losses seems like a lot to you, then you haven't been playing in casinos! This is a very likely possibility and if you play for a few hours, it happens at least once or twice.

On an added note, the Martingale betting system is a very obvious betting system that is easily spotted by casino employees. In general, land based casinos and online casinos don't like betting system users at all, with consequences varying from place to place.
