The roulette wheel has undergone considerable transformation before it reaches the game. We call it American roulette today - a wheel with 36 numbered slots plus two 0 and 00 green slots. For example, in the late 19th century, the most popular forms of roulette were numbers 1 to 28 plus 0,00, and there was an American Eagle slot. Since this roulette version only pays a bet of 27 times a bet on a number, the advantage of the house is huge.
About every 10 rotations end up at 0,00 or the eagle, which causes the house to linger in all the chips on the table. Therefore, in those days, few players can get out of the table to make a profit. Fortunately, the odds of players have improved since these early American roulette variants were developed in Louisiana and raised in Mississippi.
