Behind the Scenes of Prism - a Gambling & Economy Discord Bot

Why Build a Gambling Bot?

The inspiration for creating this bot came from user requests and my personal interest in working with probability and game theory — all without involving real money. I wanted to create something as realistic as possible, mimicking actual online casinos, complete with house edges, game balancing, and even loan systems.

The idea was to simulate a working casino economy, with built-in inflation control to ensure a stable in-game currency. While access has been limited to a closed group during development, I plan to make the bot public soon, depending on user feedback and further improvements.

Games & Features

One of the bot's core attractions is its wide selection of casino games, combining classic and modern gambling experiences. Here's a breakdown of some of the most popular games:

1. Blackjack

The classic card game where players aim to get as close to 21 as possible without going over. Players can hit, stand, double down, or surrender, with standard rules like the dealer standing on soft 17 and blackjack paying 3:2.

2. Crash

A high-risk, high-reward game featuring a rocket multiplier that increases exponentially but can crash at any moment. Players must cash out before the crash to win their wager multiplied by the displayed multiplier — waiting too long risks losing everything.

3. Diamonds

A simple slot game featuring different gem symbols.

4. Dice

Players wager on whether a random number between 0 and 100 will be above or below a target number. For example, betting on “above 90” has a 10% win chance and a x10 payout (before house edge).

5. Duel

A 1v1 wagering game where two players bet equal amounts of chips, and the winner takes it all. The house takes a small fee to prevent economy abuse.

6. HiLo

Players predict whether the next card drawn from a deck will be higher or lower than the current one. Streak-based multipliers increase payouts while making the game progressively riskier.

7. Limbo

Similar to Dice, but players wager on a multiplier rather than a number. The game's simplicity comes from choosing a payout multiplier target, and if the multiplier surpasses it, they win.

8. Mines

A 5x5 grid game where players reveal tiles, hoping to uncover gems while avoiding bombs. Revealing a gem increases the payout, while hitting a bomb results in losing everything.

9. Roulette

The classic wheel-based game, featuring both inside and outside bets just like in real casinos, offering a variety of payout options depending on risk.

10. Slide

A spinning wheel with multipliers like x2, x3, x5, and x50. Players can bet on one multiplier, and if the wheel lands on their chosen number, they win their wager multiplied by that amount.

11. Starlight Prism

A themed slot game with a gemstone design.

12. Towers

A game similar to Mines, but with rows instead of tiles. Players advance row by row on a 3-wide, 8-high field, avoiding bombs to increase their payout. Bombs are randomly placed and increase in number with each new row.

13. Wheel

Players spin a multiplier wheel with different values, including a x0 slot, risking their wager on where the wheel stops.

Key Economy & Features

The entire bot is built around a poker chip economy. Here's how its economic and social systems are designed:

1. Poker Chips & Currency Management

• In-Bot Currency: Chips are the core currency, represented with a poker chip icon.
• Bank & Transfers: Players can deposit and withdraw chips to and from their virtual bank accounts to manage spending and reduce loss risks. Players can also send chips to each other, but transfer amounts are capped based on the receiver's balance to avoid economy inflation.

2. VIP System & Rakeback

• VIP Tiers: Players can unlock higher VIP tiers by redeeming chips.
• Wager Limits: Higher VIP tiers increase max wagers and RTPs.
• Rakeback: VIP players earn back a percentage (e.g., 0.5% of all bets) as a bonus balance, which can be withdrawn later.

3. Loan & Credit System

• Loan Mechanics: Players can borrow chips with a minimum and maximum loan amount, depending on their balance.
• Interest & Repayment: Loans come with a 10% interest rate and are automatically repaid over time.
• Credit Scores: A credit score system limits loans for players with poor payment histories.

4. Leveling & XP System

• XP Gained: Players earn XP by playing games and sending messages.
• Level Rewards: Leveling up increases rewards, including bonus chips and leaderboard rankings.

Technical Details & Development

The bot was built using:

• Tech Stack: Node.js and JavaScript
• Database: A custom-built database for managing user data, wagers, balances, and game outcomes.
• Provably Fair System: Using server seeds, client seeds, and nonces like real online casinos. Every game result is provably fair and verifiable after the server seed expires every 15 minutes.

Lessons Learned & Future Plans

Building such a complex bot taught me valuable lessons about:

• Game balancing and economy design
• Database management for large-scale projects
• Ensuring fairness through cryptography-based RNG

Next Steps:

• Public Release: I plan to make the bot public soon and expand its features based on community feedback.
• Web Integration: A web-based version synchronized with the bot is already in the works.
