Plenty of information has been displayed on this website about texas hold’em, but there are other variations of the regular game. You can make a choice on which one to play depending on what rules you prefer. You can play one over the other if you find it easier or you’re more successful at winning that particular version.
One of the variants is Royal hold’em, which is played pretty much the same, but the deck has only Aces, Kings, Queens, Jacks, and Tens. Another is Pineapple and ‘crazy pineapple’, which you can learn about by watching this Youtube video. Pineapple involves discarding before the flop and crazy pineapple is discarding after the flop. Omaha hold’em is also played the same as the regular version, but each player is dealt 4 cards, which they must use 2 of, along with 3 of the community cards to create their ideal hand.
There is also Double Texas Hold’em, where players are dealt 3 cards instead of 2, and must have a common card established to play with the other cards. However, the outer cards cannot be played with each other and each player is playing two hands of 2 cards at once. And lastly, there is Double-board hold’em, which is played with two sets of community cards.
