Never played before? Start at the top and work down. Nothing here needs a password, an account, or an app — and you can stop and come back whenever you like.
You are trying to make the best five-card hand you can. You get two cards of your own, and five are turned face up in the middle for everyone to share. You can use both of your cards, one of them, or neither — whatever makes the best five.
Almost everyone at this table is learning too. Nobody minds a slow hand, and if you turn your cards over at the end and cannot work out what you have, just ask the table to read it for you. That is completely normal, even in a casino.
