a very simple game that we play is call 7s....
everyone ante's
everyone is dealth 7 cards face down (you cant look)
then one card is dealt face up. the key of the game game is to get the best hand, without flipping up a 7. the person to the left of the dealer has to beat that face up card.
IE: 8 on the open, the player has to get a card higher then 8. (but he cant look at his cards, he just flips one over)
here is a example of the game.
Player 1 is dealer, and deals 7 cards, then flips up a
5.
Player 2 flips up the first card, it is a
Player 3 flips up his cards. it is a

, he still needs to beat the 6, so he flips up another card.

, and another

. Player 3 now has a pair of 3s with a 4 kicker.
player 4 -

, 2nd card,

, 3rd card

. Player 4 has now bust out.
and it goes on till everyone but one person bust out, or the best 5 card hand wins.
very simple.
