When you are playing in an online casino and place a bet on the flip of the coin, there will be a 50-50 chance of winning. In case you have put your bet with a dollar and get your dollar back, this means that you are paid in terms of true odds. But if the casino is paying only 95 cents instead of a dollar as promised it is getting a casino house edge of 2.5%. This is the way the casino earns the money. In broader terms, the house edge is nothing but the difference of true odds and the odds which is paid by the casino when a player wins.

Every casino has a house edge chart. In case of an online casino house edge you will notice that casino's advantage will be different for various casino games. But in case of video poker and blackjack, there can be a chance of positive payback. For an online casino, you may have the option of house edge calculator. This will help you to calculate the casino odds and accordingly you can place your bet. The calculator, in fact, makes your task easier.

For roulette, the house edge will be close to 5.26%. This is applicable only if it is a double zero game. In every game there will be 36 numbers along with 0 and 00. In that case the odds of winning become 37 to 1. In case of blackjack, when the card comes out, it will change the overall make up of the other cards. Therefore there are chances that the advantage will be shifting from one player to the house. However the shifting of advantage is largely dependent on the cards that are played along with the skills of the player.
