2G\"$

Introduction

The bet known as '2G' is a straightforward proposition in roulette, launched at the Gold Coast on October 9, 2020. This bet is exclusively offered on double-zero roulette, providing a payout of 350 to 1 if the ball lands on either of the green zeros consecutively after placing your wager.

Rules

To clarify, '2G' pays off when the ball touches either green zero (0 or 00) on two successive spins after the wager is made. Combinations such as 0-0, 0-00, 00-0, or 00-00 are all valid for this bet, which is available only on double-zero roulette, featuring the same payout of 350 to 1 for winning.

Analysis

In the following table, I've broken down the analysis of the '2G' bet, highlighting that the likelihood of winning stands at (2/38)^2, which translates to a 1 in 361 chance, equating to a probability of 0.277%. The table also indicates a house edge of 2.77%.

It's noteworthy that the house edge of 2.77% is the lowest compared to all other betting options available in double-zero roulette. If a player attempts to achieve a similar outcome by wagering on the combination of 0-00, which offers a 17 to 1 payout, and subsequently places all earnings on another bet, they would actually end up with a win of 323 to 1.

The gaming documentation provided by the originator of '2G' reveals other payout opportunities ranging from 270 to 350, in increments of ten. The table below displays the corresponding house edge for each payout level.

As highlighted earlier, by placing a bet after an initial win, a player can potentially secure a payout of 323 to 1. Thus, if a win offers 320 or less, I advise pursuing the parlay strategy.

Single Zero Rules

According to the owner of '2G', there's also a variant designed for single-zero roulette. The chances of winning in this game are calculated as (1/37)*(1/37), equating to a 1 in 1369 probability or 0.0730%.

The literature indicates that casinos may offer varying payouts ranging from 1050 to 1350 to 1, in increments of 25. The table below details the house edge associated with each available payout.

By leveraging a win on the zero, players can attain a payout of 1,296 to 1 for hitting two zeros consecutively. Hence, I'd favor this approach over accepting a payout of 1,275 or less.

The perceptive reader might question the rationale behind accepting a payout of 1,300 at a house edge of 4.97% instead of opting for a parlay, especially given the single-zero roulette's lower house edge of 2.70%. The difference in expected losses linked to both betting strategies provides the answer. If the player chooses to parlay, their anticipated loss from the initial bet amounts to 1/37 = 0.0270 units, plus an average of (1/37)*36*(1/37) = 0.0263 from the potential second bet, resulting in an overall loss of 0.0533 units when combined. Dividing this by the original wager leads to a parlay house edge of 5.33%, relative to the first bet.

Triple Zero Rules

A variant of '2G' is also available for triple-zero roulette, although the most common win remains unclear. The following return table illustrates the odds for a payout of 150 to 1, displaying a house edge of 10.65% in the bottom right cell.

Taxes

It's crucial to note that casinos are required by law to issue a W-2G form for any table game winnings that meet both (1) a threshold of $600 or more, and (2) an amount at least 300 times the initial bet.
