Online Bingo — Real-Time Gaming
Develone's real-time multiplayer online bingo platform: players buy credits, play cards in live rooms and compete for prizes that are paid out automatically when each game ends.
What it is
Real-time bingo over WebSocket with two game modes, configurable rooms and a full admin back-office. The engine synchronizes ball calling, detects the first winner and pays out prizes via database procedures.
Game modes
- 🇺🇸 American (75 balls) — 5×5 B/I/N/G/O card with a central free space; win by a configurable pattern (line, cross, corners, full card, etc.).
- 🇦🇷 Argentine (90 balls) *(just launched)* — 3×9 card (15 numbers), separate Line and Bingo prizes, a per-room configurable pool split and an animated ball drum.
Who it's for
Entertainment operators, clubs and communities that want to monetize live bingo, and hosts who create and run their own rooms.
Features
- Real-time gameplay: WebSocket-synchronized games (start → countdown → play → winner), ball calling, winner detection and a progressive jackpot per room.
- Configurable rooms: card price, call speed, win pattern, visual theme, jackpot, max cards per player, purchase countdown and public or private (invite-only) rooms.
- Fair in-game selling: cards are sold during the start countdown and a card cannot win with balls called before it was bought (retroactive-claim guard).
- Game recovery: if the service restarts, in-progress games are recovered without losing state.
- Host system: any user on a plan creates and monetizes their rooms, with a margin-based commission credited in real time at the end of each game (with a double-pay guard).
- Payments: credit purchases via MercadoPago (ARS, BRL, CLP, COP, MXN, PEN, UYU) and Stripe (USD, EUR), with idempotent webhooks.
- Subscriptions: monthly plans (Free, Host Starter, Host Pro) that credit credits automatically.
- Withdrawals: bank transfer, MercadoPago, PayPal and USDT, with manual approval and instant balance hold.
- Referrals: handle-based code with automatic role promotion (Community Manager at ≥10 verified referrals).
- Live chat, rankings, transaction history and profile with avatar.
Back-office
Full admin panel (own subdomain): players, rooms, hosts, games, patterns, themes, credit packages, plans, payments, withdrawals, reports (daily/weekly/monthly revenue, per room, top players), bans and referrals.
Business rules
- Configurable per-game split: prize, jackpot, host commission and platform.
- Fairness: Fisher-Yates shuffle for balls and cards; prize payout via PostgreSQL procedures.
- Critical logic in the backend; crediting via validated, idempotent webhooks.
- Audit of sensitive actions and concurrency control (anti-fraud).
