Okay let me try.

Basic rules
-----------
up to 6 players allowed
Players start with a 0 score.
Lowest score posible is -1 and highest is 2. If a player excedes the 2 points he or she won the game, if someone has lower than -1
he or she is out of the next round, and enters back having 0 points.
It's played without jokers

Gameplay
--------
1.First, cards are shuffled..
2.Then, each player gets 2 cards that are showed to everyone and then are flipped so you can't see them anymore.
3.The cards that can't posibly a player get are taken out of the deck and put on the middle of the players, showing their value. Those cards are the lowest Xth cards where X = 52 - NumberOfPlayers x 8.
4.Each player gets one card that can't be seen by others and should be well hidden. This will be refered as the 'hidden card'
5.Players can exchange the first two cards with the players that are next to them, but can't exchange the one they can't show. If they exchange them, they have to show the cards. Two cards can not be traded for one card, players can exchange as many times they want.
6.The players can get another card if they want, or they can get two but they won't be able to exchange the next 2 times.
7.Players can exchange cards now. They can exchange one if they asked for a card, and two if they asked for none. They still have to show the cards they trade, can't trade two cards for one and this time they can only trade once.
8.Players can keep getting one or two cards like in 4, but only until one or more of the players has 7 cards in the hand. After the chance of getting new cards they can exchange, however if no one decides to get a card, everybody gets a card and there is no exchange.
9.When one or more players has 7 cards in the hand, they do the final exchange. In this one, they can trade two cards for one if both sides agree, but they still can only trade once.

Getting(or lossing) points
--------------
At any time before one or more players has 7 cards in the hand, any player can guess the hidden card of another player. If the guessing is right, that player gets +2 poins and everything should start from 1, unless the player that got his hidden cards guessed first guesses the one of the other player that guessed his. If so, the second guesser gets +3 points, and the first one doesn't gets his +2 points. If the first guesser does it wrong, he is out of that round, and his cards and hidden card can't be traded or anything.
If only one player is left in the round because the others are out because of wrong guesses, other players get -1. Players with a -1 score can't guess.

If a player guesses right someone else's hidden card when one or more players have 7 cards in the hand, that player gets +1 point and the owner of the hidden card gets -1 points. If after that someone guesses the hidden card of the one that guessed first, the first right guess is countered, meaning that no one got the +1 point or -1 point. If a player guesses wrong, he gets -1 point. A player can only try to guess once. Players with a -1 score can't guess.

If no player tries to guess after one or more players have one card, they show their hands and the hidden card. They should make pairs as they wish with all those cards they have. Each pair have their own value:
-Each club or hearth gives 1 point to the pair.
-Having both spades and diamonds gives 3 points to the pair.
-Having two 2's or 5's in one pair gives the pair 2 points.
-Having two K's in one pair gives the pair 1 point.
-Having a K and a Q in one pair gives 4 points.
-Having a K and a J in one pair gives 3 points.
-Having a Q and a J in one pair gives 2 points.
-Having a pair with K and Q, another with K and J and Q and J gives 5 points to the total.
-Having two pairs of the same value gives 6 points to the total.
-Having two pairs of the same value and another two pairs of the same value makes you the winner, unless it's a tie.
-Having an A in a pair gives it -1.
-Having more than one A couting all pairs give you -5 to the total pair value for each A.

If the player number of cards is odd, since there will be a card that won't be included inside a pair, if that card is a K, Q or J, it has a value of 1. If it's any other card it has a value of 3.

All the pair values are added up, and the one with more points gets +1 points added to the score. If two or more players are tied they all get +1. The player with the lowest total pair value gets a -1 point added to the score. All players that have a negative total get another -1, so if the one with the lowest pair also has a negative total pair value then he gets a -2 points added to the score instead.

Probably lots of room for improvement...

Links (no jokers )

Basic Concepts
- Maximum number of cards a player may have is 3.
- Play is comprised of two teams: the offense, and defense.
- The defensive team is currently playing the cards in the chain.
- The offensive team is trying to gain control of the chain.
- A chain is just a sequence of cards in order of face value (Ace = 11).
- A complete "chain" contains the card sequence ordered by face
value from 1 to King.
- A partial "chain" is any chain that doesn''t begin with a 1 card.
- "Breaking" a chain switches control of the current chain between
teams. Only the offensive team may break a chain by playing the
next card in chain.
- The offense can break a complete or partial chain by playing an
an Ace. The Ace will then be played as a 1 card.
- Points awarded are determined by the number of cards in the chain.
- A partial chain is worth at least 10 points.
- A complete chain is worth extra, 15 points.
- Once a chain has been completed, the cards are removed from play.

Object
- To earn the most points for your team before the deck of cards
runs out.

Flow of Play
- Each player initally draws a hand from the deck.
- The defensive team begins a sequence by placing a card on the play field. Then their partner
continues the chain placing a higher face card on the last card played. Team mates alternate
playing cards until they complete a chain, or their chain is broken by the offensive team.
- If a defensive player cannot play a card of a higher face,
they may return one card in their hand to the deck, shuffle,
and draw another. This counts as a turn.
- If a defensive player runs out of cards they may draw a hand,
this counts as a turn.
- As the defensive team is playing cards, the offensive team tries to gain control of the chain
by breaking the defense''s control of it. The offensive team always has the advantage to break
a chain before the next player on the defense plays their card.
- If a offensive player runs out of cards they may draw a card,
for each turn a defensive player plays. This can only be done
3 times.
- If the defense completes a chain the defense may break it by playing an ace, continuing the
chain in their control, and carrying over the points of the last chain.
- Whenever the chain is broken the teams switch roles, and the game continues.
- The team in control of the chain when it is completed earns the points for their team, and a
new chain is begun.
- The game continues until the deck has been exhausted.
