Have you read much about variants? Most poker groups I’ve played with have a dealer’s chice rule, where the deal passes around, and the current dealer names the game.
There are infinite variations, but here are the major categories:
Draw Start with a number of cards (usually five), and bet on them. Then you can discard (sometimes any number, sometimes up to four is you are keeping a ace, etc.) cards and receive new ones from the deck. Bet again, and have a show down.
Stud Start with a card face down, and a card face up. Bet, starting with the highest showing value. You will get another face-up card each round, with betting in between. End with a face-down (or ‘hole’) card. Bet again, and showdown. This is often a seven card game, but can be five. With seven cards, you choose the five you want as the final hand.
Lowball This variant can be played as any style, but you are trying for the lowest hand possible. Wilds are not often used, for obvious reasons. The “best” hand in Lowball is 23457, with at least one a different suit.
High-Low split Similar to the above, but the highest hand and lowest hand split the pot. Wilds are good here, as sometimes the same peson can take both highest and lowest.
Shared cards Since there’s only 52 cards, larger groups can’t play some variants. What you can do is have some cards in middle of the table that used by all players. For instance, the classic Texas Hold’em uses two hole cards for each player, and five face-up cards shared by everyone. This is the game that is used for the World Championships.
Have a great time!
