Arcade machines have long been a staple of gaming culture, and one of their most iconic features is the high score system. But how do these machines handle high scores and leaderboard functionality?

1. Score Tracking: Arcade games track player scores in real-time using internal memory. The game's software continuously updates the score as the player progresses.

2. Memory Storage: Classic arcade machines often use non-volatile RAM (NVRAM) or battery-backed RAM to save high scores even after the machine is powered off. This ensures that top scores remain intact.

3. Leaderboard Display: High scores are typically displayed on a dedicated leaderboard screen, showing the top players' initials and scores. This encourages competition and replayability.

4. Reset Mechanisms: Some arcade machines reset high scores after a certain period or when the machine is rebooted, while others preserve them indefinitely.

5. Modern Adaptations: Contemporary arcade systems may connect to online networks, allowing global leaderboards and cloud-based score tracking for a more competitive experience.

Understanding these mechanics highlights the ingenuity behind arcade gaming and its enduring appeal.
