[Showcase] Baccarat System

[Mice]

 

This is a Baccarat showcase. I saw a similar system a long time ago — it was the Thai version. A player once requested that I create something like it, so I decided to make my own version.

Note: Baccarat is a gambling game and is strictly not allowed for minors. Only individuals 18 years old and above are permitted to play.

 

SYSTEM MECHANICS

This is a fully-featured Baccarat mini-game scripted in rAthena, modeled after real-world casino rules. Players place bets, watch a live NPC-based card reveal animation, and receive payouts. It includes persistent rounds, SQL-tracked wagering, crash recovery, audit trails, and anti-abuse mechanisms.

Game Mechanics
Baccarat Core Rules Implemented
Two sides: Player and Banker

Bet options:
    Player
    Banker
    Draw
    Player Pair
    Banker Pair

Card draw rules are implemented accurately per real Baccarat regulations, including:
    Natural win (8 or 9)
    Player’s 3rd card rules
    Banker’s draw based on Player's 3rd card

Payout System
    Player bet: 1:1
    Banker bet: 0.95:1 (5% commission)
    Draw bet: 8:1
    Pair bets: 11:1 (if first two cards of side are identical)

Script Features
    Live Card Drawing
    Cards are drawn randomly from a 52-card deck (A–K of 4 suits).
    Each round, the system shuffles and draws up to 6 cards
        2 for Player (P1, P2), 2 for Banker (B1, B2)
        Conditional 3rd cards: P3 and/or B3

    Cards are shown using NPC representations:
        Hidden initially
        Revealed one-by-one with delays

Round Flow
    Start of Round: Players bet on options via menu.
    Timer-based lock: Betting ends after X seconds.
    Card Draw Logic: Random cards drawn, rules evaluated.
    NPC Animation: Card NPCs display sequentially with delays.
    Payout Calculation: All player bets are evaluated and rewarded.
    Wager History Logging: All results are logged to SQL.

Security & Reliability
    Bet Locking
        Players cannot place multiple bets in a single round.
        Betting only allowed during pre-draw phase.

Crash Recovery
    All bets are stored database (audit log).
    On crash or server restart:
        Unprocessed bets are logged as "Refund" in Baccarat Master NPC.
        Players can manually claim their refunds via NPC.

Persistent Tracking
    baccarat database tracks payouts with claimed flag.
    Players claim winnings from previous rounds.
    Claimed entries are logged into database history.

Zeny Overflow Prevention
    Before giving a payout, script checks if Zeny + reward exceeds Max_Zeny.
    If exceeded, reward is withheld and player is notified.

SQL Logging
    Full history in database
        Includes round ID, bets, results, payout, timestamp

    Used for:
        Wager audit
        Daily bet history per player
        Pagination & date filtering in NPC menu

Card Randomization Logic
    Deck is preloaded with all 52 unique cards (e.g., AH, 2D, KC)
    A card is selected randomly and removed from the deck to avoid duplicates.
    This ensures no duplicate cards, true randomness, and integrity.

Player Experience
    Main Menu
        Players interact with the NPC:
            Place Bet
            View Game Results (last 20 rounds)
            Check Bet History (by date)
            Claim Winnings
            View Game Rules

Visual
    Card reveals with animation and delays
    Color-coded results:
        Banker = Red
        Player = Blue
        Draw = Green
        Pair = Marked with BP / PP

Final Audit
    Rule-accurate Baccarat implementation
    Random, animated, NPC-based draw engine
    SQL-persistent and crash-resilient
    Security-audited with overflow protection
