There are a few poker variants where five cards are dealt face down, rather than four. These include Omaha and Razz.
In Omaha, each player starts with two cards face down and then three more are revealed one at a time. In Razz, each player starts with one card face down and then four more are revealed one at a time.
The key to winning in these games is to figure out what the other players have and how to use it to your advantage. For example, if you have a high card, you can try to bluff your opponents into thinking you have a lower card.
Or, if you have a low card, you can try to catch your opponents with weak hands and win with a good hand.
