Blockchain Multiplayer Game Suite (5 Titles)

Product Demo can't be shown due to strict NDA.

What it is

A comprehensive suite of blockchain-based multiplayer games including traditional board games (Backgammon, Poker, Verdict) and sports simulations (Table Soccer, 8-Ball). Each game features real-time multiplayer gameplay with server-authoritative architecture to ensure fair play and prevent cheating.

My role & ownership

Built all Unity clients; contributed maintenance across other backends; took full backend ownership for 8-Ball with an authoritative C# physics service.

Highlights

  • Built Unity clients for five multiplayer titles (Backgammon, Verdict, Poker, Table Soccer, 8-Ball Pool) under tight deadlines.
  • Server-authoritative gameplay over WebSockets (reliability, anti-cheat posture)
  • Deterministic (fixed-point) C# physics for 8-Ball as an authoritative service
  • Maintained client–server parity under fix-point physics to meet zero-latency input demands.
