These are Poker variants in which there is no draw.

There is one betting interval before the deal. The deal is normal, but the cards are dealt face up. The best hand dealt wins.

Each player receives five cards face down. Beginning with the player to the dealer's left, all the players then expose any one of their cards.

Betting intervals then alternate with further rounds of exposing one card each. On the fifth and final round of exposure, the best hand wins.

Each player receives three cards face down, with a betting interval after each round of cards is dealt.

The showdown follows immediately after the third interval.

The rank of hands (highest first) is:
1) Three of a kind.
2) Three-card straight flush.
3) Three-card flush.
4) Three-card straight.
5) Pair.
6) High card.

This game is usually played with wild cards.

There is a deal of two cards face down to each player, a single betting interval, and a showdown.

Pairs and high cards are the only hands.

Flat Poker

Originally Straight Poker, the basic game. Players are dealt five cards each; there is a betting interval, but no draw; and the winner takes the pot, either by having the best hand at a showdown, or by frightening the others into dropping.

The pot is won by either the lowest or the highest hand as follows. Minimum openers are specified — say, a pair of Jacks. If the game is opened, it proceeds as normal, the highest hand winning the pot. If no one can open, however, it changes to Lowball, and the lowest hand wins after a betting interval.
