Like any other successful business, casinos also require profits and house edge is one of the sources of their income. House edge or house advantage can be defined as predetermined percentage of odds that every casino game provides in favor of the establishment providing such services.
In some games the house edge may be quite small while some are clearly loaded in the favor of casinos. Even the games which have insignificant house edge have the ability to slowly consume money from their players.
Some games like craps on the other hand has a huge range of house edge ranging from measly one percent to more than fifteen percent. Roulette meanwhile can be considered as one of the low house edge casino games. Depending upon the type of roulette you are indulging in, house edge can vary there too!
There are many roulette systems which can be used to take advantage in the game, but in the end it is the casino which remains in the profit.
