Connect 4: Game Classification & Online Play Options

Classification Breakdown

• Combinatorial: Finite moves, zero-sum.

Online Implementations

• Discord Bots: !connect4 in many servers.

Why It's Not an MMO/RPG/etc.

No persistence, no character progression, no world, no economy. It's a session-based abstract game—like Chess or Checkers, but smaller state space.
