3. Five hole cards are dealt to each player.
4. Two fixed-limit betting rounds frame a draw.

Turn or round flow

2. Each active player exchanges 0 to 3 cards.
3. Second bidding round.
4. Showdown between the remaining players; the best hand wins.

Legal actions and obligations

• On your turn: check if there is no bet, call, raise within the limit, or fold.
• A raise must respect the fixed amount and the configured raise cap.
• Draw is limited to 3 cards; discarded cards stay out of the deck until the end of the hand.
• A folded player can no longer act or see opponents' private cards.

Score

• Order: high card, pair, two pair, three of a kind, straight, flush, full house, four of a kind, straight flush.
• Ties are broken by the values of the combination, then the kickers; the pot is split in a perfect tie.

End of game

• The hand ends when everyone except one folds or after showdown.
• The game ends after the configured number of hands, with no real-money loss.

Locked special cases and variants

• A-2-3-4-5 is the lowest straight.
• No suit ranks higher than another.
• Side pots are created if a virtual all-in mode is enabled; the fixed-limit MVP can disable them.

Artificial intelligence

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

• Easy bets with a pair or better and rarely bluffs.
• Normal evaluates the hand, position, number of opponents, likely draw, and pot odds.
• Hard combines opponent ranges, limited bluff frequency, and Monte Carlo simulation without access to hidden cards.
