House edge is the percentage of each bet
that is expected to go to the online casino Singapore in the long run. Therefore
the higher the house edge the less favorable is the game to the player. It is
not always easy to calculate the house edge in singapore online casino games. Roulette
however allows easy calculation of house edges. This article describes the
process for some bets in roulette. The simplest bet in roulette is the single
bet. In European roulette it can be placed on any of the numbers 1 to 36 or on
0. A player who wagers $1 on this bet will get $35 if he wins. He will forfeit
the $1 if he loses. Out of 37 outcomes the player will win on one outcome and
therefore the probability of winning is 1/37 or 0.027. Out of 37 outcomes the
player will lose on 36 outcomes and therefore the probability of losing is
36/37 or 0.973. The players expectation
for the $1 wagered is calculated as (35 x 0.027) – (1 x 0.973), which is
-0.027. Hence for every $1 wagered on any single number the player will expect
to lose $0.027 or the house will expect to retain $0.027. Expressed as a
percentage this is 2.7%. The neighbors of zero bet, is one of the complicated
European roulette bets, that follows a continuous sequence of numbers on the
roulette wheel of which zero is at the center. The 17 numbers covered are 22,
18, 29, 7, 28, 12, 35, 3, 26, 0, 32, 15, 19, 4, 21, 2 and 25. The wager has to
be placed as multiples of $9. The minimum $9 wager is placed as follows. $2 are
placed on the 0, 2, 3 trio; $1 is placed on each of the 4, 7, the 12, 15, the
18, 21, the 19, 22 and the 32, 35 splits and $2 are placed on the 25, 26, 28,
29 corner. The calculations are as follows. If any of 0, 2 or 3 is called the
player will win $22 at a payout of 11 to 1. He will lose the remaining $7 and
hence his net win will be $15. The probability of this happening is 3/37 or
0.08. If any of 25, 26, 28 or 29 is called the player will win $16 at a payout
of 8 to 1. He will lose the remaining $7 and hence his net win will be $9. The
probability of this happening is 4/37 or 0.11. If any of the numbers from the
five splits are called the player will win $17 at a payout of 17 to 1. He will
lose the remaining $8 and hence his net win will be $9. The probability of this
happening is 10/37 or 0.27. If any of the 20 numbers not in the given sequence
are called then the payout is zero and the player loses $9. The probability of
this happening is 20/37 or 0.54. The players expectation for the $9 wagered is
calculated as (15 x 0.08) + (9 x 0.11) + (9 x 0.27) – (9 x 0.54), which is
-0.243. Hence for every $9 wagered on the neighbors of zero bet the player will
expect to lose $0.243 or the house will expect to retain $0.243. Expressed as a
percentage this is also 2.7%. In fact all singapore online casino bets in European Roulette have a
house edge of 2.7%.
