Quiz answers: (The questions are repeated for quick reference)

1. True or false?
On a double zero Roulette wheel if the Casino paid 37 to 1 for a straight up bet (single number win) there would be no Casino advantage despite the presence of the two zeros on the wheel. By paying 35 to 1, total 36 instead of 38, the Casino gains 2 units or 5.26% of your win.

Answer: True. Provided the casino also pays the outside bets accordingly. See next question.

2. True or false?
On a double zero Roulette wheel if you placed 18 units (chips):
a) All on Black, even money bet
b) 1 unit on each of the 18 Black numbers, straight up bets
And a Black number wins, you would collect 36 units including your winning bet, in either case.

Answer: True. They are two equal bets:
Case a) An even-bet win is paid an equal amount, that is 18 units, plus your winning bet 18 units = 36 units.
Case b) A straight-up bet is paid 35 units, plus your winning bet 1 unit = 36 units.
So, wherever you place your bet you are always betting on numbers. If you placed 12 units on a dozen-bet (outside bet) or placed 12 straight-up bets on each of the 12 numbers represented by that dozen, in either case you would still collect 36 units if any of those 12 numbers wins. The 'outside' bets are just short-cuts to betting on a group of numbers. When the casino pays a 1 to 1 'even money' bet, 5.26% of your win has been deducted. With no casino advantage, it should pay you 1 + 2/18 of your bet and you get to keep your bet, or 20 units in the example above (20 payout + 18 your bet = 38). The zeros are not the casino advantage. They are two playable [Green] numbers.

3. True or false?
On a double zero Roulette wheel in one cycle (38 spins) if you bet one unit on Black even-money-bet all the time, in theory:
a) You would win 18 spins and lose 20.
b) The Casino would gain its 5.26% advantage on the 18 winning spins only.

Answer: True. The 38 slots of the roulette wheel are made up of 18 Blacks, 18 Reds and 2 Greens (0, 00):
Case a) 18 Blacks = 18 wins, 18 Reds plus 2 Greens = 20 losses.
Case b) The casino gains the advantage by paying the winner less than what it should. Therefore, you need to win in order for the casino to deduct its 5.26% advantage thus the advantage gain can only take place on the 18 winning spins. On the losing spins there is nothing to pay, therefore no 5.26% deduction, no casino advantage gain.

4. True or false?
Adding zeros to the Roulette wheel is the only way for the Casino to gain an advantage and that is the reason they have been added.

Answer: False. The zeros have been added to the wheel to create a payout advantage without changing it at 35 to 1, total 36, because 36 is divisible by 2, 3, 4, 6, 12 and 18 (which are the possible betting combinations on the roulette table *) and therefore best suited to simplify the payout of all the winning bets. The casino could still gain an advantage by paying, say, 33 to 1 and use a wheel with no zeros, but they will need to use fractions of units when paying out splits and street bets and the outside bets. This would be time consuming and confusing.

* Except for the five-number bet: 1, 2, 3 and the two zeros.

5. True or false?
The Casino advantage at Roulette is in the reduced payout taken only when you win. When you win the Casino wins. The Casino takes 5.26% (or 2.7% for a single zero wheel) of your win each time you win and only when you win - wherever you place your bet.

Answer: True.

Tip: For an efficient betting strategy aim to win more money in fewer winning spins.

Big tip: Don't challenge the mathematical advantage of the casino. You cannot eliminate or change it and you don't need to. It is not your adversary unless you choose to make it that way and you will lose - slowly but surely. It is relatively small considering the sums of money that can be won or lost in a very short space of time. Think of it as a necessary and acceptable contribution or a tax towards paying the cost of the gaming equipment and salaries of the casino personnel. Remember, you pay it if and when you win only.
