Arcade game machines have long been a hub for competitive multiplayer gaming, especially in fast-paced titles where split-second reactions matter. To ensure smooth synchronization between players, these machines employ several advanced techniques.

1. Frame Synchronization: Many arcade games use deterministic lockstep synchronization, where each player's inputs are synchronized frame-by-frame. This ensures all machines process the same inputs simultaneously, maintaining consistency.

2. Low-Latency Hardware: Arcade cabinets are optimized with high-performance processors and minimal input lag to reduce delays. Dedicated local networks or direct wiring between machines further cut down latency.

3. Rollback Netcode (for Online Play): Modern arcade systems may integrate rollback netcode, predicting player inputs to compensate for network delays and correcting errors if predictions are wrong.

4. Master-Slave Architecture: In local multiplayer setups, one machine often acts as the "master," processing all inputs and broadcasting results to "slave" units to keep gameplay synchronized.

5. Optimized Game Design: Fast-paced arcade games are designed with simplified physics and predictable mechanics to minimize synchronization challenges.

These methods ensure that even in high-speed competitive play, arcade games deliver a seamless and fair multiplayer experience.
