In the community poker card the players besides having the normal personal cards (not visible and usable to the other players)  can use them for getting a better score with the cards called  “community cards”, these cards are laid out on the table game, visible and usable for everybody.   

The number of personal cards and community cards to be used to get a good score varies from game to game.

Crazy Pineapple is a particulate variation of the Texas Hold'em.

The presence of two rows of community cards on the table game (called board).

Very similar to the Texas Hold'em but with some differences on the set of the community cards.   
After the first hand the dealer prepares 3 community cards, put in a vertical way on the table game, this operation also follows in the 2nd and 3rd hand. At the end of the third hand there is the showdown where each player will use the community cards to attain the best score, but following the rules of the three of a kind (also called the tic tack toe in the  Anglo-Saxon countries).
