It is much more loyal to the player. In it there is one or more rules that reduce the casino advantage. For example, at a rate equal to the odds and roll of "zero", burns only half rates. Or, at the rate for a rare chance, bid fully preserved and proceeds to the next round. Through these rules the player's advantage is reduced to minus 1.35%.

In a typical embodiment, the  roulette house edge is 2.7%, the American - 5.3%.

Whether it is beneficial for the player. Sometimes yes, sometimes no. All depends on what stakes you play and how many spend time at the roulette table. Calculate the house edge in this case is not so simple as it seems.
