BlueAngel,

Expected effect of variance on an even money game (simplified) = ( + or -) x (three standard deviations) x (square root of the number of spins)

Expected effect of the house edge on a double zero wheel = ( -5.26%) x (number of spins)

Now after, 5000 spins on the double zero wheel which has the bigger effect on your bankroll?

**Expected effect of variance** = (+ or -) 3 x (Square root of 5000) = winning or losing around** 212.13 units**

**Expected effect of the house edge **= -5.26% x 5000 = losing around **263 units.**

As you can see, the house edge is the main reason players lose after they've played enough spins.

It does not matter whether you play all of the spins in one setting, or whether you play them off and on over several days or weeks.

The house edge eats away at your bankroll, until you reach the point where even a three standard deviation fluctuation is not enough to climb back up to even.
