We all know that No Limit Texas Holdem is the most popular poker game in the world. Sin City Holdem is a variation of this popular game in which the player gets one hole card down, then a round of betting. Then the community flop is dealt out, followed by the 2nd round of betting. At this point players are dealt their second hole card, creating the similar feel of Texas Holdem. There is now a turn card dealt, followed by betting and a river card followed by betting. This is a versatile game that can be played in many formats; though we envision its best fit is through the medium of online poker.
