Building a Real-time, Multiplayer Poker Game: Phase 1 of 3

Building a Server‑Authoritative Poker Engine: Phase 1 of 3

I'm a high school student developer, and for the past few months I've been building a real‑time multiplayer Texas Hold'em game from scratch. This is Phase 1: a fully functional local prototype that runs on Node.js + Socket.IO.

Important: This is not deployable yet. It's a local‑only testing prototype. I have two more major phases planned before it's ready for public release on platforms like Itch.io, CrazyGames, and Poki.

🛠️ What's Built So Far

  • Real‑time multiplayer: up to 12 players per table
  • Full game logic: side pots, rebuys, all‑in, showdown
  • Spectator mode: watch games and request to join (host approved)
  • 20‑second turn timer: auto‑fold on timeout with visual countdown
  • Floating emojis: YouTube‑live style reactions
  • Sound effects: synthesised via Web Audio API (no external files yet)
  • Host controls: kick players, edit chips, change password, toggle rebuys, change max players
  • Responsive UI: works on desktop and mobile

🧠 Technical Highlights

The entire game state is managed server‑side to prevent cheating. Some of the more interesting parts I had to figure out:

  • Side‑pot algorithm: calculating multiple pots when players go all‑in
  • Hand evaluator: ranking 5‑card hands from 7 cards (with kickers)
  • Turn timer: server‑enforced 20s limit with auto‑fold
  • Spectator flow: separate chat, request‑to‑join with host approval

🔮 What's Coming (Phases 2 & 3)

  • Phase 2: major content and mechanics additions (the fun stuff).
  • Phase 3: complete aesthetic overhaul and UI polish, making it ready for public platforms.

💬 Why I'm Sharing Now

I want early feedback on the core logic, UX, and any bugs before I build more on top of it.

Since I'm a student doing this in my free time, I'll respond to feedback and fix reported issues within 2 weeks (best case). If I can't make that window, I'll reply to let you know when I can, and ping you again once the fix is live.
