Telegram Fast Three Dice Game Source Code Deployment Guide: Node.js Telegram Group Gambling System Setup

Recently I took on a Telegram group game project where the client wanted a fast-three dice system running inside a Telegram group, supporting manual top-up and withdrawal scoring. The system was developed with Node.js and integrated natively with Telegram. The entire setup took three days, with bot integration and odds configuration being the most time-consuming parts. This article documents the pitfalls I encountered and the key configurations, for anyone with similar needs.

1. Game Play Features Explained

This fast-three game system is not a simple web version but deeply integrates with a Telegram Bot for group play. Users place bets directly in the group by sending command messages, and the bot announces results in real time. The specific play modes are as follows:

1. Single Play Mode (2x Odds): Big (11-17 points), Small (4-10 points), Odd (5,7,9,11,13,15,17), Even (4,6,8,10,12,14,16). Command format such as “Odd 100” or “Big 200”. Triplets are excluded; single bet capped at 5000U.
2. Compound Play Mode: Big Odd (11,13,15,17, 3.4x odds), Small Even (4,6,8,10, 3.4x odds), Big Even (12,14,16, 4.4x odds), Small Odd (5,7,9, 4.4x odds). Triplets excluded; capped at 5000U.
3. Special Play Mode: Triplet bet (25x odds, capped at 600U), Pair bet (2x odds, capped at 5000U), Straight bet (6x odds, capped at 1000U).
4. Point Kill Play Mode: The sum of three dice is the point kill number. 4/17 points at 50x odds, 5/16 points at 25x odds, 6/15/7/14 points at 12x odds, 8/13/9/10/11/12 points at 6-8x odds. Capped at 10-500U.
5. Point Kill Triplet Play Mode: Designated point triplet (such as “1 Triplet 100”), 125x odds, capped at 10-100U.

2. Deployment Preparation and Environment Checklist

Although the game play is complex, the deployment environment requirements are actually modest. The following is the verified checklist:

• Server: Recommended 2 cores 4GB RAM minimum. Node service memory usage is not high, but Redis and database need some headroom.
• Runtime Environment: Node.js 16.x+, Redis 6.x, MySQL 5.7+, PM2 process manager.
• Telegram Bot: Apply for a bot in advance through @BotFather, obtain the Token, and disable privacy mode (otherwise the bot cannot see group messages).
• Domain and HTTPS: Webhook receiving Telegram callbacks must use HTTPS; SSL configuration is recommended.
• Payment Channel: Manual top-up and withdrawal mode requires a customer service account system. Automatic mode can integrate USDT-TRC20 payment interfaces.
• Group Settings: Make the bot a group administrator, otherwise it cannot read group messages or send draw results.

3. Common Issues and Pitfall Records

3.1 Bot Not Receiving Group Messages

The most common issue after deployment is the bot acting “dead” in the group. In 90% of cases, this is because privacy mode was not disabled in BotFather, or the bot is not a group admin. Fix path: BotFather → /mybot → your bot → Bot Settings → Group Privacy → Turn off.

3.2 Webhook Repeatedly Failing Causing Bet Unresponsiveness

Telegram has strict webhook validation. If the SSL certificate chain is incomplete or a non-200 status code is returned, the webhook is automatically deactivated. We recommend using certbot for a proper certificate, and implement error catching on the Node side to ensure it always returns 200 to Telegram.

3.3 Odds Calculation Precision Issues Causing Customer Complaints

In early versions, JavaScript default floating-point calculations were used. When betting 100U on a triplet and winning, the payout showed 2499.9999U instead of 2500U. After switching to the decimal.js library for precise calculations, all amounts are rounded to two decimal places, and complaints dropped to zero.

3.4 Concurrent Betting Causing Database Deadlocks

During peak times with 20 people betting simultaneously, MySQL deadlock errors appeared. The solution was to change the balance validation and deduction logic to Redis atomic operations (Redis transactions or Lua scripts), with the database only keeping logs, drastically reducing load.

4. Customization and Expansion Recommendations

Based on subsequent client requests, this source code supports several secondary development extensions:

• Automatic Top-Up and Withdrawal: Integrate Tron chain USDT listening addresses. Deposits auto-credit, withdrawals auto-transfer, reducing customer service workload by 80%.
• Agent Commission System: Give agents a separate backend to track subordinate betting volume and earn percentage commissions.
• Multi-Group Simultaneous Operation: One backend binds multiple Telegram groups. Different groups can have different odds and water levels.
• Anti-Cheat Risk Control: Record user betting IP and device fingerprinting. Trigger manual review for abnormal behavior (such as consecutive triplet wins).
• APP Packaging: Wrap the web version into iOS/Android apps using UniApp, distributed via TestFlight or enterprise signing.

Tip: Telegram gambling groups are in a gray area in some countries. Before operating, be sure to confirm local legal risks. We recommend only conducting business in jurisdictions that allow online gambling, and prominently display “This group is for entertainment only; please bet responsibly” within the group.

5. FAQ Frequently Asked Questions

Q1: How many groups can this system run simultaneously?

A single 2-core 4GB RAM server has been verified to run 15-20 active groups simultaneously (200 online users per group). If more are needed, scale Node processes horizontally. PM2 cluster mode supports multi-core utilization.

Q2: How long after recharge does it take to credit?

In manual top-up and withdrawal mode, a customer service agent performs the operation, usually completed within 5 minutes. In automatic USDT mode, after on-chain confirmation (about 1-3 minutes), the system auto-credits.

Q3: How does the triplet sweep rule work?

When a triplet is drawn, all players who bet on “Big/Small/Odd/Even/Compound/Pair/Straight” lose. Only players who correctly bet on the “Triplet Play” or “Point Kill Play” modes receive payouts at the corresponding odds.

Q4: Can other games like Beijing Racing or Lucky Airship be added?

Yes. The system uses a modular draw engine. Adding new games only requires configuring draw rules and odds in the backend, and the frontend bot automatically adapts to the new command format.

⚠️ Important Notice: This system is for technical learning and demonstration purposes only. Online gambling is strictly regulated in most countries and regions. Unauthorized operation may face legal risks. Please be sure to comply with the laws and regulations of your location, and never use it for illegal gambling business.
