Texas Hold'em

Variant played: No limit · virtual chips · Version 1.0.0

Objective

Make the best five-card hand from seven available cards, or win the pot by forcing opponents to fold.

Setup

1. 2 to 9 players; the button, small blind, and big blind rotate each hand.
2. Each player is dealt two private cards.
3. Five community cards are dealt in three stages: flop (3), turn (1), river (1).
4. Chips are free, fictional, and non-convertible.

Turn or round flow

1. Preflop: action starts with the player to the left of the big blind.
2. Flop, turn and river: action starts to the left of the button among active players.
3. On each turn: check, bet, call, raise, virtual all-in, or fold.
4. After the river, reveal the cards at showdown and form the best five-card hand.

Legal actions and obligations

• A minimum raise must be at least equal to the last full raise.
• A player cannot bet more than their virtual stack.
• Side pots are split according to eligible contributions.
• An all-in player remains eligible only for the pots they contributed to.
• Private cards remain secret until showdown or an authorized voluntary reveal.

Score

• Same ranking as five-card draw poker; exactly five cards count.
• The main pot and each side pot are awarded separately; ties are split, with any odd chip going according to the defined position.

End of game

• The hand ends when everyone except one folds or after pots are awarded at showdown.
• Rooms may be limited by time or by number of hands; there are no withdrawals.

Locked special cases and variants

• If fewer than five community cards are needed after all active players are all-in, the server deals the remaining board without further betting.
• An incomplete all-in raise does not necessarily reopen the action under standard no-limit rules.
• Heads-up uses the button as the small blind and first preflop actor.

Artificial intelligence

The AI uses only its hand, public cards, the allowed history, and the legal actions sent by the server.

• Easy relies mainly on the immediate strength of its cards.
• Normal uses position, stack depth, pot odds, board texture, and simplified starting ranges.
• Hard estimates equity with Monte Carlo, keeps controlled bluff frequencies, and reads only public information.
