Snake Eyes

Introduction

Snake Eyes is a craps variant offered at the SkyCity casino in Auckland, New Zealand. It is pretty much the game of craps with all the best bets removed leaving only the sucker bets. To add insult to injury, they depress the odds on some of them compared to the normal stingy American rules. A few new sucker bets are added to the mix too. However, they do up the win on the Snake Eyes bet from 30 up to 32.

Rules



Following is a list of the bets available. All pays are indicated on a "to one" basis.

Footnotes:

* To roll a number the "hard way" means that both dice must land on the same number. For example, a hard 8 would be a 4-4.
** To roll a number the "easy way" means that both dice must land on different numbers. For example, a hard 8 could be rolled as a 2-6 or 3-5.
