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.
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.
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%.
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
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
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.
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.
