Oh okay. What are you working on, or is it a secret?

It's classical card game, of course online multiplayer. But the interface will be more similar to yahoo games than to what duelboard currently uses.  I will post the link when it's finished.

If it's Texas Hold'em, I'm going to be a happy man.

[Dodger]

What is Texas Hold'em??

Talk About Poker

Texas Hold'Em is the darling of pro Poker players, spectators, and the media. It's an aggressive, flashy, intense and unpredictable game that gets the dollars on the table and changing hands like no other contemporary form of Poker. All that and it looks deceptively simple to play. The old hard-nut players may prefer 7-Card Stud, but everyone else is in love with Hold'Em. It's no coincidence that Hold'Em is the game that players at the World Series of Poker play to determine who takes home $1,000,000 and the champion's custom 14-karat gold bracelet.

Hold'Em is clearly a descendant of 7-Stud in that players form a five-card hand from seven available cards, but that's where the similarity ends. In fact, only two cards are actually held by the player as pocket cards. The other five are open, dealt to the middle of the table and shared by all players. Of course this means there are less cards in play, which is why Hold'Em typically seats nine or more players at the table.

The dealer in Hold'Em is marked by a disk called the button. For each hand the button rotates to the left. Players are identified by their seat position. The dealer is seat one, the player to the dealer's left is seat two and so on, clockwise around the table to the player on the dealer's right which is typically seat nine.

In practice, casino Hold'Em has a fixed (house) dealer and the button rotates around the table simply to mark the rotation of theoretical dealer. Betting position significantly affects a player's opportunities so the button's position in not simply symbolic.

Hold'Em comes in many low-limit/high-limit forms. Beginner games are typically $1-$2 or $2-$5, but the high end can be as much as $300-$600, $500-$1000 or more. Regardless of the limits, Hold'Em is designed to be a money game. Instead of a small ante in 7-Stud, Hold'Em uses two forced bets, the blinds, to get Bets on the table right from the beginning of the game.
The Open

The first player to the dealer's left -- seat two -- is the small blind and must kick in half the lower limit ($5 in a $10-$20 game). Seat three is the big blind and must kick in the full value of the lower limit ($10 in a $10-$20) game.

The deal rotates clockwise around the table beginning with the player to the big blind's left. Each player is dealt their first pocket card in turn, then their second.

Since the blinds opened with their forced bets, seat four, the player to the big blind's left, bets first. They Call by matching the big blind ($10, the lower limit) and may also Raise by kicking in the big limit, $20 in our $10-$20 example game. In this round Checking is not permitted. If the player doesn't want to Call, they may Fold.

The blinds in Hold'Em are live in that they can Call (Check to seat three), Raise, or Fold when the betting has returned to them.
The Flop

Once the first betting round has completed, the dealer lays out the first three community cards in the center of the table. This is called the flop.

This betting round begins with the blinds, or the first remaining seat on the dealer's left. Checking is permitted now and for the rest of the hand. Bets are placed at the lower limit ($10 in our example).
The Turn

A fourth community card it dealt onto the table.

Betting begins with the blinds, as before. Now, and for the rest of this game, Bets and Raises are at the high limit ($20). As such, the turn is the first expensive street.
The River

The fifth and final community card is dealt.

This is also an expensive street: Bets and Raises are all at the high limit ($20).
The Showdown

As in 7-Stud, the best 5 card hand wins. Players may form their final hands from any combination of the table cards and their own pocket cards, even ignoring the pocket cards and using only the table cards if they wish.

One point on which Hold'Em departs from other poker games is the option for any player to see another player's pocket cards once they've been mucked. Provided the requesting player has Called or Raised the last Bet made, they simply ask the dealer and the mucked cards will be retrieved and shown. Since asking the dealer isn't generally possible online, sometimes, game logs will show the final mucked cards.

To the newcomer this move may seem incredibly invasive, especially if they come from a Draw poker background where such a move would be heresy. However, in the Hold'Em context, it's one of the few ways to gain insight into an opponent's play style. And how and when the pocket cards are played is a critical part of the game.

Texas Hold'em General Rules
   

In hold’em, players receive two downcards as their personal hand (holecards), after which there is a round of betting. Three boardcards are turned simultaneously (called the “flop�) and another round of betting occurs. The next two boardcards are turned one at a time, with a round of betting after each card. The boardcards are community cards, and a player may use any five-card combination from among the board and personal cards. A player may even use all of the boardcards and no personal cards to form a hand (play the board). A dealer button is used. The usual structure is to use two blinds, but it is possible to play the game with one blind, multiple blinds, an ante, or combination of blinds plus an ante.

Object: The best possible five card poker hand, using any combination of hole cards and community cards, wins the pot.

Betting Rounds
1.The dealer deals each player their own two cards face-down (pocket cards)
2.1st betting round
3.The dealer burns a card then turns over three community cards face-up
(the flop)
4.2nd betting round
5.The dealer burns another card then turns over 1 more community card (the turn,4th street)
6.3rd betting round
7.The dealer burns another card then turns over 1 final community card (the river,5th street )
8.Last betting round
9.Showdown (Every remaining player shows hand with bettor showing first)

All remaining players must use one of the following choices at the showdown:

   1. Two pocket cards & three boardcards
   2. One pocket card & four boardcards
   3. No pocket cards & five boardcards (called playing the board)

Texas Hold'em Rules

1. If the first holecard dealt is exposed, a misdeal results. The dealer will retrieve the card, reshuffle, and recut the cards. If any other holecard is exposed due to a dealer error, the deal continues. The exposed card may not be kept. After completing the hand, the dealer replaces the card with the top card on the deck, and the exposed card is then used for the burncard. If more than one holecard is exposed, this is a misdeal and there must be a redeal.

2. If the flop contains too many cards, it must be redealt. (This applies even if it were possible to know which card was the extra one.)

3. If the flop needs to be redealt because the cards were prematurely flopped before the betting was complete, or the flop contained too many cards, the boardcards are mixed with the remainder of the deck. The burncard remains on the table. After shuffling, the dealer cuts the deck and deals a new flop without burning a card. [See – Explanations, discussion #2, for more information on this rule.]

4. If the dealer turns the fourth card on the board before the betting round is complete, the card is taken out of play for that round, even if subsequent players elect to fold. The betting is then completed. The dealer burns and turns what would have been the fifth card in the fourth card’s place. After this round of betting, the dealer reshuffles the deck, including the card that was taken out of play, but not including the burncards or discards. The dealer then cuts the deck and turns the final card without burning a card. If the fifth card is turned up prematurely, the deck is reshuffled and dealt in the same manner. [See – Explanations, discussion #2, for more information on this rule.]

5. If the dealer mistakenly deals the first player an extra card (after all players have received their starting hands), the card will be returned to the deck and used for the burncard. If the dealer mistakenly deals more than one extra card, it is a misdeal.

6. You must declare that you are playing the board before you throw your cards away; otherwise you relinquish all claim to the pot.

Yes

[zzboots]

There are already a million and one websites (yes I counted) in which people can play texas hold 'em and other poker games.

Having more unique card games would be a better angle to take.

Along those lines, when I play euchre at yahoo games, people are always having special tournaments with variants on rules.  If you would feature euchre with several different game options, you could draw in a large crowd looking to play a particular style.  Of course this idea can be applied to all sorts of card games with options to change the rules.

Also http://spogg.com has a nice collection of unique online, multiplayer games such as tetris and pictionary in case you are looking for any ideas.

[SiR gUt]

OhhHhHHhhhhhhhh we can start tournaments for those too!!

[matlu]
