# 2G'\$

## Introduction

2G'\$ is a simple roulette side bet that began a run at the Gold Coast on October 9, 2020. It is played on double-zero roulette only. The bet pays 350 to 1 if the ball lands in either green number (zero or double-zero) twice in a row after the bet is made.

## Rules

As stated in the introduction, 2G'\$ wins if the ball lands in a green number (zero or double-zero) twice in a row after the bet is made. Any combination of green numbers is allowed (0-0, 0-00, 00-0, or 00-00). It is offered on double-zero roulette only. Wins pay 350 to 1.

## Analysis

The following table shows my analysis of 2G'\$ at a win of 350 to 1. It shows the probability of winning is (2/38)^2 = 1 in 361 = 0.277%. The lower right corner shows a house edge of 2.77%.

### 2G'\$

Event Pays Probability Return
Win 350 0.002770 0.969529
Loss -1 0.997230 -0.997230
Total   1.000000 -0.027701

It should be emphasized the 2.77% house edge is lower than every other bet in double-zero roulette. If the player tried to accomplish the same thing by betting on the 0-00 combination, which pays 17 to 1, and let all winnings ride one more bet, then he would win 323 to 1.

Gaming literature from the owner of 2G'\$ mentions other pays are available from 270 to 350, by tens. The following table shows the house edge of each.

### Alternate Pays — Double Zero

Win House Edge
270 24.93%
280 22.16%
290 19.39%
300 16.62%
310 13.85%
320 11.08%
330 8.31%
340 5.54%
350 2.77%

As mentioned above, the player can achieve a win of 323 to 1 by parlaying after a first win. Thus, I would recommend doing that if a win pays 320 or less.

## Single Zero Rules

Game literature by the owner of 2G'S also mentions a version for single-zero roulette. The probability of a win in that game is (1/37)*(1/37) = 1 in 1369 = 0.0730%.

The literature says the casino many choose from a win of 1050 to 1350 to 1, by 25's. The following table shows the house edge of each available pay.

### Single Zero Version

Win House Edge
1,050 23.23%
1,075 21.40%
1,100 19.58%
1,125 17.75%
1,150 15.92%
1,175 14.10%
1,200 12.27%
1,225 10.45%
1,250 8.62%
1,275 6.79%
1,300 4.97%
1,325 3.14%
1,350 1.31%

By parlaying a first win on zero himself, the player can achieve a win for two consecutive zeros of 1,296 to 1. Thus, I would do that rather than accept a win of 1,275 or less.

The astute reader may wonder why the player should accept a win of 1,300, at a house edge of 4.97%, rather than parlay, when the house edge in single-zero roulette is 2.70%. The answer has to do with the way the house edge is defined. If the player parlays, his expected loss between the two bets is the sum of 1/37 = 0.0270 units from the first bet and an average of (1/37)*36*(1/37) = 0.0263 from the possible second bet for a total of 0.0533 units. Divide that by the one-unit original bet and you have a house edge of 5.33% by parlaying, relative to the initial bet.

## Taxes

Players should also be mindful that by law the casino will issue a W2-G form for a table game win, not counting the return of the original wager, that is both (1) \$600 or more and (2) 300 or more times the amount bet.
